代码永远不会在退出时运行 [英] Code Never Runs Upon Exit

问题描述

大家好，

我有一个Winform问题.我想使用Environment.Exit(1)退出应用程序.但是，当我使用这种方法时，退出代码之前的代码不会执行.有什么想法吗?这是我的代码.只需注意一下，如果我省略Environement.Exit(1)代码，该代码将成功运行.

Hi all,

I have an issue with a winform. I would like to exit the application using Environment.Exit(1). However when I use this approach the code before the exit code does not execute. Any thoughts? Here is my code. Just as a note, the code runs successfully if I leave out the Environement.Exit(1) code.

public void ShowForm(System.Windows.Forms.Form frm, string id)
{
    frmMain=frm;
    this.Show();

    object empty = null;

    axW.Navigate("http://localhost:2124/Studiebogservice/_Ankomst/LabelPrint.aspx?id=" + id, ref empty, ref empty, ref empty, ref empty);

    for (; axW.ReadyState != SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE; )
    {
        System.Windows.Forms.Application.DoEvents();
    }

    axW.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINT, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER, ref empty, ref empty);

    Environment.Exit(1);
}

推荐答案

它可能确实提示运行，并准备了命令-但作为异步过程.然后是Environment.Exit并终止与应用程序相关的所有进程，包括您刚刚准备打印的进程.

Environment.Exit是重要的一步-这是一个异常终止，它会关闭所有内容，而无需等待它们完成，保存数据或执行其他任何操作.

It probably does get cued to run, and the commands for it are prepared - but as an asynchronous process. Then along comes Environment.Exit and terminates all processes associated with the application, including those you have just prepared to print.

Environment.Exit is a big step - it is an abnormal termination, and it shuts everything down, without waiting for them to finish, save data, or do anything else.
