I am going to write a small program that query Amazon web service for book information.
Given some sample I found online, I wrote;
namespace TestWCF
{
class Program
{
static void Main(string[] args)
{
Console.Write("Enter keyword: ");
var line = Console.ReadLine();
if (line == null)
{
return;
}
using (var svc = new AmazonSearchPortClient())
{
var keywordReq = new KeywordRequest
{
locale = "us",
type = "lite",
sort = "reviewrank",
mode = "books",
keyword = line,
tag = "associate-id",
devtag = "????????????"
};
var productInfo = svc.KeywordSearchRequest(keywordReq);
foreach(var detail in productInfo.Details)
{
Console.WriteLine(detail.ProductName);
}
}
}
}
This does not work as it returns authenticate failure at the line;
var productInfo = svc.KeywordSearchRequest(keywordReq);
I am not sure what information I should put into the tag and devtag fields. Someone says I should put associate ID but what I shall put into the devtag?
Many thanks,
Regards.

i'm trying to create an application where data in a list must be inserted into a database table at once. I made some research and found out that this is possible using user-defined table types where in c# a datatable is used and passed to a stored procedure that is executed. now my problem is that there are no data tables in Xamarin.Android. so I thought to use a list instead. my idea was to create a list in the application and pass it to the webservice method, and in my webservice method I receive the list and convert it to a datatable then pass it as a parameter to the stored procedure. I wrote the following codes:
in my webservice:
[WebMethod]
public bool insrt_dt(List<Class1> lst)
{
SqlParameter param;
SqlConnection conn = new SqlConnection(new DBConnection().ConnectionString);
DataTable dt = list_to_dt(lst);
SqlCommand cmd = new SqlCommand("Insert_Customers", conn);
cmd.CommandType = CommandType.StoredProcedure;
if (conn.State == System.Data.ConnectionState.Closed)
{
conn.Open();
}
param = new SqlParameter("#tblcustomers", dt);
param.Direction = ParameterDirection.Input;
param.DbType = DbType.String;
cmd.Parameters.Add(param);
cmd.CommandTimeout = 300;
int a=cmd.ExecuteNonQuery();
if (a > 0)
{
return true;
}
else return false;
}
}
Class1:
public class Class1
{
public int id { get; set; }
public string name { get; set; }
public string country { get; set; }
}
in my Xamarin.Android app
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.activity_main);
Button btn = FindViewById<Button>(Resource.Id.button1);
btn.Click += delegate
{
wr.WebService1 ws = new wr.WebService1();
wr.Class1 class1 = new wr.Class1();
List<wr.Class1> lst = new List<wr.Class1>(){
new wr.Class1() { id = 1, name = "hgf", country = "khg" },
new wr.Class1() { id = 2, name = "hgf", country = "khg"} };
ws.insrt_dt(lst);
ws.insrt_dtCompleted += Ws_insrt_dtCompleted;
};
}
private void Ws_insrt_dtCompleted(object sender, wr.insrt_dtCompletedEventArgs e)
{
bool l = e.Result;
if (l == true)
Toast.MakeText(this, "khh", ToastLength.Long).Show();
else
Toast.MakeText(this, "ijo'pioo", ToastLength.Long).Show();
}
}
but I keep getting this error:
Argument 1: cannot convert from 'System.Collections.Generic.List<app_dt.wr.Class1>' to 'app_dt.wr.Class1[]
so I used these lines instead
new wr.Class1() { id = 1, name = "hgf", country = "khg" },
new wr.Class1() { id = 2, name = "hgf", country = "khg"} };
wr.Class1[] class1s = lst.ToArray();
ws.insrt_dt(class1s);
now I don't get an error, but it doesn't work, I mean why does it say that the webservice method input must be an array and I've created it as a list. any suggestions for this?
As i know, Xamarin do not support System.Data.SqlClient. If you want to use the database for the Xamarin android project, you could use the SQLite.NET.
Install the package from the NuGet.
NuGet: sqlite-net-pcl https://www.nuget.org/packages/sqlite-net-pcl/
For the code sample about how to use the database in Xamarin, you could check the link below. https://learn.microsoft.com/en-us/xamarin/get-started/quickstarts/database?pivots=windows
For Xamarin.Android, you could check the sample code in the link below. https://learn.microsoft.com/en-us/xamarin/android/data-cloud/data-access/using-sqlite-orm
I am onboarding alone on an existing project that do not have any unit test. My first goal before any refactoring is to cover 100% of the code. I would like to avoid any regression.
I have read how do I mock sqlconnection or should I refactor the code? but my case as you can see below is quite different cause I need to do more than stub simply the sqlConnection. Basically, I need to mock the db. I would like to know the best approach to achieve it.
(By the way, I do not want to use any ORM such as Entity).
Below the code of the repository :
public class HotelRepository : IHotelRepository
{
private readonly IDbConnection _dbConnection;
private readonly ILogService _loggerService;
public HotelRepository(IDbConnection dbConnection, ILogService loggerService)
{
_dbConnection = dbConnection;
_loggerService = loggerService;
}
public HotelDo GetByRid(string rid)
{
return Find(rid).FirstOrDefault();
}
public List<HotelDo> Find(string text)
{
try
{
_dbConnection.Open();
var items = new List<HotelDo>();
using (var command = _dbConnection.CreateCommand())
{
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "dbo.HotelSearchByRidOrName";
command.Parameters.Add(new SqlParameter("#Text", text));
using (var reader = command.ExecuteReader(CommandBehavior.CloseConnection))
{
while (reader.Read())
{
items.Add(new HotelDo()
{
Name = SqlExtension.ReaderToStringConverter(reader["Name"]),
Id = SqlExtension.ReaderToIntConverter(reader["Id"]),
Rid = SqlExtension.ReaderToStringConverter(reader["RIDHotel"]),
IdPms = SqlExtension.ReaderToNullableIntConverter(reader["IdPms"]),
LinkResaWeb = SqlExtension.ReaderToStringConverter(reader["LinkResaWeb"]),
LinkPms = SqlExtension.ReaderToStringConverter(reader["LinkPms"]),
IdBrand = SqlExtension.ReaderToNullableIntConverter(reader["IdBrand"]) ?? 0,
IsOnline = SqlExtension.ReaderToBoolConverter(reader["IsOnline"]) ?? false,
CodeCountry = SqlExtension.ReaderToStringConverter(reader["CodeCountry"])
});
}
}
}
return items;
}
catch (Exception e)
{
var errorMessage = $"HotelRepository Find, text {text} ";
_loggerService.Trace(LogSeverity.Error, errorMessage, e);
throw new DalException() { Source = errorMessage, };
}
finally
{
_dbConnection.Close();
}
}
public List<HotelDo> GetAll()
{
try
{
_dbConnection.Open();
var items = new List<HotelDo>();
using (var command = _dbConnection.CreateCommand())
{
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "dbo.HotelGetAll";
using (var reader = command.ExecuteReader(CommandBehavior.CloseConnection))
{
while (reader.Read())
{
bool.TryParse(reader["IsOnline"].ToString(), out var isOnline);
items.Add(new HotelDo()
{
Id = SqlExtension.ReaderToIntConverter(reader["Id"]),
Rid = SqlExtension.ReaderToStringConverter(reader["RIDHotel"]),
Name = SqlExtension.ReaderToStringConverter(reader["Name"]),
CodeCountry = SqlExtension.ReaderToStringConverter(reader["CodeCountry"]),
LinkPms = SqlExtension.ReaderToStringConverter(reader["LinkPms"]),

IdBrand = SqlExtension.ReaderToNullableIntConverter(reader["IdBrand"]) ?? 0,
LinkResaWeb = SqlExtension.ReaderToStringConverter(reader["LinkResaWeb"]),
IsOnline = isOnline
});
}
}
}
return items;
}
catch (Exception e)
{
var errorMessage = $"HotelRepository GetAllHotels";
_loggerService.Trace(LogSeverity.Error, errorMessage, e);
throw new DalException() { Source = errorMessage, };
}
finally
{
_dbConnection.Close();
}
}
}
Thank you for your help
So based on what you've got I've set up a test frame for you to follow. I've removed less important components for breviety.
Before you you jump in I just want to give my 2 cents, if you don't know how to do this sort of thing you seem to be more or less in a junior position or less experiance with C# and also found your self in a more or less mature company that doesn't care about the development deparment, since an uncovered project just get's thrown your way says you don't have alot of resources to go about to imrpove the code base.
Test only the things that have business value (can you put a price on the piece of logic if it brakes)
Delivering stuff faster will make you look better as a programmer (noone in the business gives a damn about test covarage)
Study hard, get your experiance, good reputation and don't be afraid to get the hell out of there as soon as you start getting bored.

I need to get sitecore information that collected from anonymous users to give him availability to export it or opt out - [GDPR]
any idea about contact ID for anonymous !
The way of doing it is dependent on the sitecore version.
Sitcore 9 you can use right to be forgotten
Sitecore 8+ you have to implement the feature from scratch.
Regarding Anonymous user - If the user is really anonymous, then you done need to worry about the GDPR (my view). But sometimes we map user email and sensitive personal info to anonymous user by using forms or WFFM. You can use email address of that user to query xDB (Contact Identifiers) to get the contact and contactID. Then reset informations.
Also: please note that based on WFFFM save action config, anonymous user will store in Core DB and Contact List.
To forget a user, you can use the following code. It will execute the ExecuteRightToBeForgotten function on the contact and scrub their data.
Forget User
public bool ForgetUser()
{
var id = _contactIdentificationRepository.GetContactId();
if (id == null)
{
return false;
}
var contactReference = new IdentifiedContactReference(id.Source, id.Identifier);
using (var client = _contactIdentificationRepository.CreateContext())
{
var contact = client.Get(contactReference, new ContactExpandOptions());
if (contact != null)
{
client.ExecuteRightToBeForgotten(contact);
client.Submit();
}
}
return false;
}
Fake up some data
public void FakeUserInfo()
{
var contactReference = _contactIdentificationRepository.GetContactReference();
using (var client = SitecoreXConnectClientConfiguration.GetClient())
{
// we can have 1 to many facets
// PersonalInformation.DefaultFacetKey
// EmailAddressList.DefaultFacetKey
// Avatar.DefaultFacetKey
// PhoneNumberList.DefaultFacetKey
// AddressList.DefaultFacetKey
// plus custom ones
var facets = new List<string> { PersonalInformation.DefaultFacetKey };
// get the contact
var contact = client.Get(contactReference, new ContactExpandOptions(facets.ToArray()));
// pull the facet from the contact (if it exists)
var facet = contact.GetFacet<PersonalInformation>(PersonalInformation.DefaultFacetKey);
// if it exists, change it, else make a new one
if (facet != null)
{
facet.FirstName = $"Myrtle-{DateTime.Now.Date.ToString(CultureInfo.InvariantCulture)}";
facet.LastName = $"McSitecore-{DateTime.Now.Date.ToString(CultureInfo.InvariantCulture)}";
// set the facet on the client connection
client.SetFacet(contact, PersonalInformation.DefaultFacetKey, facet);
}
else
{
// make a new one
var personalInfoFacet = new PersonalInformation()
{
FirstName = "Myrtle",
LastName = "McSitecore"
};
// set the facet on the client connection
client.SetFacet(contact, PersonalInformation.DefaultFacetKey, personalInfoFacet);
}
if (contact != null)
{
// submit the changes to xConnect
client.Submit();
// reset the contact
_contactIdentificationRepository.Manager.RemoveFromSession(Analytics.Tracker.Current.Contact.ContactId);

How to get anonymous contact ID using Sitecore API?
I'm using this code but can't find the contact ID in xconnect DB.
using (XConnectClient client = Sitecore.XConnect.Client.Configuration.SitecoreXConnectClientConfiguration.GetClient())
{
try
{
// var enumerator = client.Interactions.Where(x => x.DeviceProfile.Id == contactId).GetBatchEnumeratorSync(10);
Event ev = new Event(Guid.NewGuid(), DateTime.UtcNow) { Duration = new TimeSpan(20) };
var reference = new ContactReference(contactId);
Contact contact = client.Get<Contact>(reference, new ContactExpandOptions() { });
if (contact != null)
{
client.ExecuteRightToBeForgotten(contact);
client.Submit();
}
}
catch (XdbExecutionException ex)
{
// Manage exceptions
}
}
You can get it with the code new IdentifiedContactReference(Sitecore.Analytics.XConnect.DataAccess.Constants.IdentifierSource, Tracker.Current.Contact.ContactId.ToString("N")) This is the xDB identifier which is the identifier anonymous contacts get.
Here is the code I use _contactIdentificationRepository is in a Foundation repository. _contactIdentificationRepository.GetContactReference() will get the anonymous or identified contact reference.
Call xConnect
var contactReference = _contactIdentificationRepository.GetContactReference();
using (var client = SitecoreXConnectClientConfiguration.GetClient())
{
// we can have 1 to many facets
// PersonalInformation.DefaultFacetKey
// EmailAddressList.DefaultFacetKey
// Avatar.DefaultFacetKey
// PhoneNumberList.DefaultFacetKey
// AddressList.DefaultFacetKey
// plus custom ones
var facets = new List<string> { PersonalInformation.DefaultFacetKey };
// get the contact
var contact = client.Get(contactReference, new ContactExpandOptions(facets.ToArray()));
.....

I have an app that allows users to log in via facebook, once user enters their credentials - My api request saves the user onto the database and auto-generates a user token(This is unique to each user). In order to display user specific details once user logs in - the token needs to be referenced. I am trying to get this token to the PCL project but it returns null just for the token. When I tried passing another string like name, it passes the correct value. Any help will be much appreciated.Thanks

You can use the MessagingCenter.
Messages may be sent as a result like a button click, a system event or some other incident. Subscribers might be listening in order to change the appearance of the user interface, save data or trigger some other operation.
More Info
I don't really now if its good idea use static fields in App class. Xamarin access all fields with service locator, App.Current.[property] I will suggest you try to change these fields to public
string _Token;
public string Token
{
get { return _Token; }
}
public void SaveToken(string token)
{
_Token = token;
}
and use it with App.Current.SaveToken(token) or App.Current.Token
