在VB.NET中,FormClosed和FormClosing事件有什么区别？

Private Sub frmTerminal_TCP_FormClosing(sender As Object,e As FormClosingEventArgs) Handles MyBase.FormClosing

End Sub


Private Sub frmTerminal_TCP_FormClosed(ByVal sender As Object,ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed

End Sub

FormClosing发生在FormClosed之前.想想FormClosing,就像要求您在退出程序之前保存文档的对话框一样.它让您有机会取消窗口的终止.

表单关闭后触发FormClosed.从MS documentation开始：

The FormClosed event occurs after the form has been closed by the user or by the Close method or the Exit method of the Application class. To prevent a form from closing,handle the FormClosing event and set the Cancel property of the CancelEventArgs passed to your event handler to true.
