比较这个C#(小提琴)

public class Program
{   
    public static void Main()
    {
        IFoo test;
        test = new Impl();
        test = new NoImpl();                
    }
}
public interface IFoo {}
public class NoImpl {}
public class Impl : IFoo {}

到这个VB(小提琴).

Public Module Module1
    Public Sub Main()
        Dim test as IFoo
        test = new Impl()
        test = new NoImpl()
    End Sub
End Module

Public Interface IFoo
End Interface

Public Class NoImpl
End Class

Public Class Impl 
    Implements IFoo
End Class …
