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

我使用表单作为弹出对话框来显示进度条，但我不希望用户能够关闭它.

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

这样做:

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

为了回应 pix0rs 的担忧 - 是的，您将无法以编程方式关闭应用程序是正确的.但是，您可以在关闭表单之前简单地删除 form_closure 事件的事件处理程序:

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();
