RaiseEvent in VB.Net

C# prefers a syntax more near to the actual implementation of events. VB is able to code in both ways.

So instead of

Public Class Sample Public Event MyEvent () Public Sub DoSomething () RaiseEvent MyEvent() End Sub End Class

You can Write

Public Class Sample Public Delegate Sub MyEventDelegate() Public Event MyEvent () Public Sub DoSomething () RaiseEvent MyEvent End Sub End Class

VB creates this delegate invisible to you. C# only allows you the second way and does not have the RaiseEvent keyword. So you have to deal with the delegate itself.

Public Class Sample Public Delegate Sub MyEventDelegate() Public Event MyEvent () Public Sub DoSomething () If Not MyEvent Is Nothing Then MyEvent() End If End Sub End Class

So for your code, all you have to write is:

RaiseEvent ErrorEvent(new ArgumentException("blablabla"), Nothing)
