当用户单击C#应用程序标题栏中的“关闭”按钮时,不想退出程序

[英]Don't want to exit program when user click on Close button in titlebar of C# app

Working on development of C# application. 从事C#应用程序的开发。

I want to keep Close button on top right in title bar, but if end users click on it, all I want is that he gets info window that he can not close application until some other proper button. 我想在标题栏中保持“关闭”按钮在右上角,但是如果最终用户单击它,我所希望的就是他获得了一个信息窗口,他无法关闭应用程序,除非其他适当的按钮。

Is it possible to achieve? 有可能实现吗?

Tnx in adv! 广告中的Tnx!

Add an event handler to the OnClosing event of the form. 将事件处理程序添加到窗体的OnClosing事件。 The event argument contains an element Cancel . 事件参数包含元素Cancel Set it to true and it won't close. 将其设置为true不会关闭。

Essentially something like this: 本质上是这样的:

private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
    e.Cancel = !stuffdone;
}

You can handle the FormClosing event event handler like this 您可以像这样处理FormClosing事件事件处理程序

private void Form_FormClosing(object sender, FormClosingEventArgs e)
{
    //there can be other reasons for form close make sure X button is clicked
    // if close button clicked
    if (e.CloseReason == CloseReason.UserClosing)
    {
        e.Cancel = true;
    }
}
