这篇博客介绍了如何在C#中创建一个能够与GUI交互的Windows服务。通过利用Windows API函数，如WTSQueryUserToken、DuplicateTokenEx和CreateProcessAsUser，可以在服务上下文中模拟用户会话，从而启动具有图形界面的应用程序。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Principal;
using System.Runtime.InteropServices;

namespace SchedulerServer
{
    class Interop
    {
        public static void CreateProcess(string app, string path)
        {
            bool result;
            IntPtr hToken = WindowsIdentity.GetCurrent().Token;
            IntPtr hDupedToken = IntPtr.Zero;

            PROCESS_INFORMATION pi = new PROCESS_INFORMATION();
            SECURITY_ATTRIBUTES sa = new SECURITY_ATTRIBUTES();
            sa.Length = Marshal.SizeOf(sa);

STARTUPINFO si = new STARTUPINFO();
si.cb = Marshal.SizeOf(si);

int dwSessionID = WTSGetActiveConsoleSessionId();
result = WTSQueryUserToken(dwSessionID, out hToken);

            if (!result)
            {
                ShowMessageBox("WTSQueryUserToken failed", "AlertService Message");
            }

            result = DuplicateTokenEx(
                  hToken,
                  GENERIC_ALL_ACCESS,
                  ref sa,
                  (int)SECURITY_IMPERSONATION_LEVEL.SecurityIdentification,
                  (int)TOKEN_TYPE.TokenPrimary,
                  ref hDupedToken
               );

            if (!result)
            {
                ShowMessageBox("DuplicateTokenEx failed", "AlertService Message");
            }
