什么是禁用的最好办法替代 + F4 在C＃赢形式prevent从关闭的形式向用户？

What is the best way to disable Alt + F4 in a c# win form to prevent the user from closing the form?

我使用的一种形式弹出对话框显示进度条，我不希望用户能够将其关闭。

I am using a form as a popup dialog to display a progress bar and I do not want the user to be able to close it.

推荐答案

这做这项工作：

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    e.Cancel = true;
}

编辑：在回答pix0rs关注 - 是的，你是正确的，你将无法以编程方式关闭该应用程序。但是，你可以简单地关闭窗体之前删除的事件处理程序form_closing事件：

In response to pix0rs concern - yes you are correct that you will not be able to programatically close the app. However, you can simply remove the event handler for the form_closing event before closing the form:

this.FormClosing -= new System.Windows.Forms.FormClosingEventHandler(this.Form1_FormClosing);
this.Close();
