如何解決這個事件相關的錯誤在VB.net（Windows Phone 7）

Question

嗨下面的代碼給了我一個錯誤，我不太確定如何解決。任何人都可以幫忙嗎？

代碼：

Public Event hw As EventHandler 

Private Sub view_hw(sender As Object, eventArgs As Object) 
    If hw IsNot Nothing Then 
     hw.Invoke(Me, New EventArgs()) 
    End If 
End Sub 

錯誤：

Error 1 'Public Event hw(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event. 

Answer 1

Public Event hw As EventHandler 

Private Sub view_hw(sender As Object, eventArgs As Object) 
    RaiseEvent hw(Me, New EventArgs()) 
End Sub
