Try the following. You will see that C# actually passes the out param value
into the function! As has been said, this is because it is a C# feature, not
a CLR/CLS feature.
--- VB.Net ---
Imports System.Runtime.InteropServices
Public Class TestServer
' Fool C# into thinking this is an out only param
Public Shared Sub DoStuff(<Out()> ByRef x As Integer)
Console.WriteLine("Out param is {0}", x)
End Sub
End Class
--- C# ---
using System;
namespace ThunderMain.Test {
class TestClient {
static void Main(string[] args) {
int y=42;
TestServer.DoStuff(out y);
Console.ReadLine();
}
}
}
