跟踪vb.net中的所有事件

我唯一能想到的方法就是 Reflection 枚举所有事件并连接一个通用处理程序,该处理程序将是PITA。

框架事件有问题吗?如果是这样的话,微软在提供事件生命周期/调用顺序方面做得很好。

下面是一个全局事件捕获例程:

Private Sub WireAllEvents(ByVal obj As Object)
    'Grab all of the events for the supplied object
    Dim Events = obj.GetType().GetEvents()
    'This points to the method that we want to invoke each time
    Dim HandlerMethod = Me.GetType().GetMethod("GlobalHandler")
    'Loop through all of the events
    For Each ev In Events
        'Wire in a handler for the event
        ev.AddEventHandler(obj, [Delegate].CreateDelegate(ev.EventHandlerType, Me, HandlerMethod))
    Next
End Sub
Public Sub GlobalHandler(ByVal sender As Object, ByVal e As EventArgs)
    'Probably want to do something more meaningful here than just tracing
    Trace.WriteLine(e)
End Sub

打电话给它 WireAllEvents(Me.DataGridView1) 提供您的对象。几乎所有MS事件都使用SENDER/E(包括DataGridView)格式,但如果出于某种原因不使用,我认为此代码将出错。但我刚刚用DataGridView和Form测试了它,它工作正常。
