Question

I have an interface defined in C# project:

public interface IForm
{
    bool IsDisposed { get; }
    void Show();
}

I implemen

Answer 1

Use the shadows keyword if you want to override the standard methods of the Form and replace them with the ones defined in your interface otherwise you are required to use a different name as they are treated as two separate methods.

Public Class Form1
    Inherits Form
    Implements IForm

    Public Shadows Property IsDisposed As Boolean Implements IForm.IsDisposed

    Public Shadows Sub Show() Implements IForm.Show
        ' replaces original method in Form class
    End Sub

End Class

Alternative:

Public Class Form2
    Inherits Form
    Implements IForm

    Public Property IsDisposed1 As Boolean Implements IForm.IsDisposed

    Public Sub Show1() Implements IForm.Show
        Me.Show() ' Original method still exists and is accessible like this
    End Sub
End Class
