invoking wsdl operations through c# - web-services

Question

I need to create a win forms app in VS 2013, which will take a wsdl file as a webReference. It will invoke an wsdl:operation "Init" which will send the following xml to the web service :
The Wsdl contains the operation:
<wsdl:operation name="Init">
<wsdl:input message="wl:InitRequest"/>
<wsdl:output message="wl:InitResponse"/>
</wsdl:operation>
The Init SOAP xml
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://www.asdfgh.org/lala/log">
<soapenv:Header/>
<soapenv:Body>
<web:Init>
<web:Phase>`TST`</web:Phase>
</web:Init>
</soapenv:Body>
</soapenv:Envelope>
It will send a response back InitResponse:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://www.asdfgh.org/lala/log">
<soapenv:Header/>
<soapenv:Body>
<wl:InitResponse xmlns:wl="http://www.asdfgh.org/lala/log">
<Data>
<NUMBER>1234</NUMBER>
<TEXT1>ABCDEF</TEXT1>
<TEXT2>QWERTY</TEXT2>
</Data>
</wl:InitResponse>
</soapenv:Body>
</soapenv:Envelope>
How to I read the response back and show the ouput in a MessageBox.Show();
Below is the class formed by the wsdl on the Init.
public partial class Init {
private string phaseField;
/// <remarks/>
public string Phase {
get {
return this.phaseField;
}
set {
this.phaseField = value;
}
}
}
Below is the class formed by the wsdl on InitResponse(funny thing is, it did not create any class named InitResponse. It has created InitResponseData -- I wonder why)
public partial class InitDSDResponseData {
private string NUMBERField;
private string TEXT1Field;
private string TEXT2Field;
/// <remarks/>
public string NUMBER {
get {
return this.NUMBERField;
}
set {
this.NUMBERField = value;
}
}
/// <remarks/>
public string TEXT1 {
get {
return this.TEXT1Field;
}
set {
this.TEXT1Field = value;
}
}
/// <remarks/>
public string TEXT2 {
get {
return this.TEXT2Field;
}
set {
this.TEXT2Field = value;
}
}
}
On a button click event, I want to show the response xml in a Message Box as a string. How should I proceed? How do I invoke the Init operation through c#?
