推荐答案

如果你可以使用 System.Management，那就很简单了:

If you can use System.Management, it's easy enough:

    private static int GetParentProcess(int Id)
    {
        int parentPid = 0;
        using (ManagementObject mo = new ManagementObject("win32_process.handle='" + Id.ToString() + "'"))
        {
            mo.Get();
            parentPid = Convert.ToInt32(mo["ParentProcessId"]);
        }
        return parentPid;
    }

否则你可能不得不通过 CreateToolhelp32Snapshot 调用 P/Invoke 调用像这样

Otherwise you may have to resort to P/Invoke calls via CreateToolhelp32Snapshot like this
