哪個事件處理程序首先被調用？

Question

請參閱下面的代碼：

Imports ComponentAndControl 

Public Class Form1 

    Delegate Function Compare1(ByVal intNumber1 As Integer, ByVal intNumber2 As Integer) As Boolean 
    Public Event e() 
    Public Event e2(ByVal o As Object, e As EventArgs) 

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load 

     Dim Test As New TestEventArgs 
     Test.Name = "Bert" 
     Test.Age = 34 

     RaiseEvent e2(Me, Test) 
    End Sub 

    Public Sub TestHandler4(ByVal o As Object, ByVal e As TestEventArgs) Handles Me.e2 
     MsgBox(e.Name) 
     MsgBox(e.Age) 
    End Sub 

    Public Sub TestHandler5(ByVal o As Object, ByVal e As TestEventArgs) Handles Me.e2 
     MsgBox(e.Name) 
     MsgBox(e.Age) 
    End Sub 
End Class 

Public Class TestEventArgs 
    Inherits EventArgs 

    Public Name As String 
    Public Age As Integer 

End Class 

哪個事件處理程序首先調用？即TestEventHandler4或TestEventHandler5？有沒有可能配置這個？

Answer 1

.Net規範中未定義調用MultiCastDelegate時的事件順序。通常按照它們添加的順序調用它們，按照代碼順序調用，但不要依賴它。

UPDATE

這MSDN文章似乎表明，調用順序是現在保證是加入他們的順序。實際上我沒有實際驗證過這一點，我不確定添加了自動連線事件的順序。 https://msdn.microsoft.com/en-us/library/system.multicastdelegate(v=vs.110).aspx
