c# - 强制终止进程

Question

我有一个连续运行的循环，作为一个进程来检查 mstsc.exe 是否正在运行。

for (; ; )
{
    System.Diagnostics.Process[] pname = System.Diagnostics.Process.GetProcessesByName("mstsc");

    if (pname.Length != 0)
    {

    }
    else
    {
        System.Diagnostics.Process.Start(@"mstsc.exe");
    }
    System.Threading.Thread.Sleep(3000);
}

问题是在注销、重启或关机时我得到了这个。

我试图在 Form_Closing 上或用

结束进程

Microsoft.Win32.SystemEvents.SessionEnded += 
  new Microsoft.Win32.SessionEndedEventHandler(SystemEvents_SessionEnded);

我还是明白了...

我怎样才能强制这个进程正确终止？

Answer 1

当进程有子进程时会发生这种情况。你必须杀死整个进程树。

Kill process tree programmatically in C#

来自上面链接的代码(由 Gravitas 提供):

/// <summary>
/// Kill a process, and all of its children.
/// </summary>
/// <param name="pid">Process ID.</param>
private static void KillProcessAndChildren(int pid)
{
    ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_Process Where ParentProcessID=" + pid);
    ManagementObjectCollection moc = searcher.Get();
    foreach (ManagementObject mo in moc)
    {
        KillProcessAndChildren(Convert.ToInt32(mo["ProcessID"]));
    }
    try
    {
        Process proc = Process.GetProcessById(pid);
        proc.Kill();
    }
    catch (ArgumentException)
    {
        // Process already exited.
    }
}
