Dim ContextMenunew As ContextMenu = New ContextMenu ContextMenunew.MenuItems.Clear() Dim myMenuItem1 As New MenuItem() Dim myMenuItem2 As New MenuItem() myMenuItem1 = New MenuItem() myMenuItem1.Text = "添加" ContextMenunew.MenuItems.Add(myMenuItem1) AddHandler (myMenuItem1.Click), AddressOf MenuClick myMenuItem2 = New MenuItem() myMenuItem2.Text = "删除" ContextMenunew.MenuItems.Add(myMenuItem2) AddHandler (myMenuItem2.Click), AddressOf MenuClick
