Override vb.net Function in C#

Question

I'm a little confused about this simply things. How Can I override vb.net Function in C#. I wrote this code in vb.net in vb.net class:

 Public Overridable Function Test1() As Integer
        Dim t1 As Integer
        Return t1
 End Function 

I want to override this in C# class which inherits through vb.net class. Method code below.

    public override  int Test1()
    {
        int t1 = 2;
        return t1;
    }

I receive error: No suitable method to override.

Answer 1

I just tested this and it seems to work. My code:

Public Class TestClass
    Public Overridable Function Test() As Integer
        Dim t1 as Integer
        Return t1
    End Function
End Class

C#:

using MyVBProject;

public class CSharpClass : TestClass
{
    public override int Test()
    {
       int t1 = 2;
       return t1;
    }
}

some things to check:

• The C# project has a reference to the VB project
• The C# file is using the vb namespace
• The C# class does actually derive from the VB class CSharpClass : TestClass

That can be because to put a public override, all class has to be public, instead, you can try to write "protected override" and not "public override". Otherwise, I think your question is alredy in stack overflow: link to question
