Foreach Variable in C# generated code
In C# a foreach variable can't be assignable, so to avoid a compilation error, the line must be commented. In VB.Net the iteration variable can be assigned so, this restriction is not applied.
Recommendations
Check the logic of the original VB6 function. In some cases the nothing assignation to the iteration variable is a way to stop the cycle. If this is the case use the break statement instead.For the given example, just remove the commented line and the EWI.
Sample VB6
Public Function TestCommentedLines(ByVal P() As String) As Integer
Dim S
Dim Count As Integer
For Each S In P
If Not S IsNothing Then
MsgBox(S)
Count = Count + 1
S = Nothing
End If
Next S
TestCommentedLines = Count
End Function
Target C#
public int TestCommentedLines( string[] P)
{
int Count = 0;
foreach (string S in P)
{
if (S != null)
{
MessageBox.Show(S, Application.ProductName);
Count++;
//UPGRADE_NOTE: (2041) The following line was commented.
//S = null;
}
}
return Count;
}
