如何在VB.NET中删除事件处理程序

Question

  

可能重复：
  VB.NET RemoveHandler & Anonymous Methods

如果我添加这样的事件处理程序：

AddHandler s.Click, AddressOf Panel1_Click

我怎样才能删除事件处理程序？

Private Sub Panel1_click(ByVal sender As Object, ByVal e As System.EventArgs)
    ' Remove code
End Sub

Answer 1

您可以使用RemoveHandler运算符执行此操作：

Private Sub Panel1_click(ByVal sender As Object, ByVal e As System.EventArgs)
    Dim panel As Panel = CType(sender, Panel)
    RemoveHandler panel.Click, AddressOf Panel1_Click
End Sub

Answer 2

与添加它的方式相同：

RemoveHandler s.Click, AddressOf Panel1_Click
