如何以托管方式在.NET中获取父进程

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process currentProcess = Process.GetCurrentProcess();
        Process parentProcess = GetParentProcess(currentProcess.Id);

        if (parentProcess != null)
        {
            Console.WriteLine("父进程的进程ID：{0}", parentProcess.Id);
            Console.WriteLine("父进程的进程名：{0}", parentProcess.ProcessName);
        }
        else
        {
            Console.WriteLine("无法获取父进程信息。");
        }
    }

    static Process GetParentProcess(int id)
    {
        Process process = Process.GetProcessById(id);
        return GetParentProcess(process);
    }

    static Process GetParentProcess(Process process)
    {
        int parentPid = 0;
        using (Process p = new Process())
        {
            p.StartInfo.FileName = "WMIC.exe";
            p.StartInfo.Arguments = string.Format("process {0} get parentprocessid", process.Id);
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardOutput = true;
            p.Start();
            string output = p.StandardOutput.ReadToEnd();
            p.WaitForExit();

            int.TryParse(output.Trim(), out parentPid);
        }

        if (parentPid > 0)
            return Process.GetProcessById(parentPid);
        else
            return null;
    }
}
