推荐答案

2选项:

1.在窗体设计器或代码中，将Form.CancelButton属性设置为取消"按钮.然后，当按下取消"按钮或单击退出"键(或即使关闭了对话框)时，窗体的DialogResult将为"DialogResult.Cancel".

2.使用keyDown事件并捕获KeyCode:

2 Options:

1. In your Forms designer or in your code, set the Form.CancelButton property to your "Cancel" button. Then, when the Cancel button is pressed, or the Escape key is clicked (or even if the Dialog is closed) then the DialogResult of the form will be "DialogResult.Cancel."

2. Use keyDown event and trap KeyCode:

Private Sub Form2_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
    If e.KeyCode = Keys.Escape Then Me.Close()
End Sub

试试吧！
