FormClosed和FormClosing事件之间的区别

Question

在VB.NET之间有什么区别FormClosed和FormClosing事件？

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

Answer 1

FormClosing之前发生过FormClosed.想一想FormClosing在退出程序之前要求您保存文档的对话框.它让您有机会取消窗口的终止.

FormClosed表单关闭后触发.从MS文档:

FormClosed事件发生在用户或Close方法或Application类的Exit方法关闭表单之后.若要防止窗体关闭,请处理FormClosing事件并将传递给事件处理程序的CancelEventArgs的Cancel属性设置为true.
