创建一个httphandler并移动注销代码，您可以通过调用该处理程序来使用它。

As @SimonWhitehead said, you should add a class and call the Logout method from both the MasterPage and the LoginControl . But if you insist, this is a way of doing it, pretty much making the method visible to the next level:

LoginUserControl :

Public Sub DoLogout()
    'Do something'
End Sub

Protected Sub Logout_Click(sender As Object, e As EventArgs) Handles Logout.Click
    DoLogout()
End Sub

HeaderUserControl :

Public Sub DoLogout()
    Me.LoginUserControl.DoLogout()
End Sub

and finally

MasterPage :

Protected Sub Logout_Click(sender As Object, e As EventArgs) Handles Logout.Click
    HeaderUserControl.DoLogout()
End Sub

This would call your method in the LoginUserControl control.
