Interface problem

[John]

Hi

I have implemented an interface as below. I am getting a "Class
'HelloWordPlugin' must implement 'Sub PerformAction()' for interface
'IPlugin'." error. What is the problem and how can I fix it?

Thanks

Regards


Public Interface IPlugin
Sub PerformAction()
End Interface

Public Class HelloWordPlugin
Implements IPlugin

Public Sub PerformAction()
Console.WriteLine("Hello, World!")
End Sub
End Class

VB.NET doesn't determine which method in a class implementing an interface
implements a certain method of the interface by comparing the methods'
names. Instead, you will have to declaratively specify which method of the
interface the method implements.

Public Interface IPlugin
Sub PerformAction()
End Interface

Public Class HelloWordPlugin
Implements IPlugin

Public Sub PerformAction()
Console.WriteLine("Hello, World!")
End Sub
End Class

\\\
Public Class HelloWorldPlugin
Implements IPlugin

Public Sub PerformAction() Implements IPlugin.PerformAction
...
End Sub
End Class
