c# For Each On object that it's Ienumerable - casting

Question

I have strange question but i hope someone can help me i have this vb.Net Code
For Each navigation In navigations
If obj.GetType().GetProperty(navigation.Name) IsNot Nothing Then
Dim childs = obj.GetType().GetProperty(navigation.Name)
Dim childValues = childs.GetValue(obj, Nothing)
If childValues Is Nothing Then
Continue For
End If
For Each item In childValues
If item Is Nothing Then
Continue For
End If
SetValues(item, entityState)
Next
End If
Next
childValues values is object but i know it's a list of navigation properties.
and i can do thi in vb.net
For Each item In childValues
' Do Stuff
Next
sometimes childValues is Entity collection of TEntity and sometimes it's FixupCollection. but in both scenario the above code works well.
now i want to change this code to c# and i don't know how can i do that
can please someone explain to me how vb works and how can i do this in c#?

To start off, you can replace the ifs with a .Where filter
navigations.Where(n => n.GetType.GetProperty(n.Name) != null) // nothing?
Then "convert" each Navigation into its children:
.Select(n => obj.GetType().GetProperty(navigation.Name))
.Select(n => childs.GetValue(obj, null)) // nothing?
Then replace the if with another .Where filter:
.Where(chVals => chVals != null) // nothing?
before iterating over them
.ForEach(chVals =>
chVals.Where(item => item != nothing) // Not sure what nothing means in VB...
.ForEach(item => SetValues(item, entityState))
);
