问题描述

我的应用程序创建了一些进程，当用户单击表单的红色取消按钮时，我想杀死它们.所以我在Form1_FormClosing()中编写代码，但没有结果.我在函数中编写的代码是正确的，我已经检查过了.

{

    int i = 0;
    while (i < p.MyProcess.Count)
    {
        if (!p.MyProcess[i].HasExited)
        {
            p.MyProcess[i].Kill();
            p.MyProcess[i].Close();

        }
        i++;
    }
    p.MyProcess.Clear();
}

推荐答案

在您的Button中.单击事件处理程序"吗?
或者，您可以根据自己的喜好在事件处理程序中调用的方法中.

In your Button.Click Event Handler?
Or perhaps in a Method you call from your Event Handler, depending on your taste.

private void button_Click(Object sender, EventArgs e)
{
    // Code goes here.
}

或者，如果您愿意:

Or, if you like:

private void button_Click(Object sender, EventArgs e)
{
    KillProcesses();
}

private void KillProcesses()
{
    // Code goes here.
}

如果您需要在多个Forms或Classs中使用这段确切的代码，请考虑将其放在单独的Class中并使其静态(假设您不需要实例字段来杀死进程).

If you need this exact piece of code in multiple Forms or Classes, consider placing it in a seperate Class and making it static (assuming you don''t need instance fields to kill processes).
