Question

c#中如何实现在点击窗口的关闭按钮时,使窗口最小化,而不退出程序?

Answer 1

FormClosing事件里
e.Cancel = true;
this.MinimizeBox = true;

Answer 2

添加代码：

protected override void WndProc(ref Message m)
{
const int WM_SYSCOMMAND = 0x0112;
const int SC_CLOSE = 0xF060;
if (m.Msg == WM_SYSCOMMAND && (int)m.WParam == SC_CLOSE)
{//捕捉关闭窗体消息
// User clicked close button
this.WindowState = FormWindowState.Minimized;
return;
}
base.WndProc(ref m);
}
