How can I close my active windows form without using mouse click, but by using keyboard keys (shortcut/accelerated keys) in C#?

推荐答案

您只需要订阅KeyDown事件处理程序，然后在按下某个键时会收到一个事件.在这种情况下，您可以检查按下了哪个键.例如，如果要在按下返回"时关闭表单，则可以使用:

You just need to subscribe the KeyDown event handler and then you will get an event when a key is pressed. In this event you can check which key was pressed. If for example you want to close your form when "Return" is pressed, then you might use:

private void KeyDown(object sender, KeyEventArgs e)
{
  if (e.KeyCode == Keys.Return)
    this.Close();
}

在页面Keydown或keyup事件中，应编写如下代码，
对于VB，

In Page Keydown or keyup event write code like this,
For VB,

If e.KeyCode = Keys.Esc Then
Me.close()
End If

对于C#，

For C#,

this.Close();

只需使用您的表单keydown事件即可.

Hi,

Just use your form keydown event.

private void form_KeyDown(object sender, KeyEventArgs e)
{
 if(e.KeyCode == Keys.Escape)
 {
  // use message box if you need.
  this.close();
 } 
}

干杯:)

Cheers :)
