using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Security.Principal; using System.Runtime.InteropServices; using System.IO;   namespace ConsoleApplication3 {     internal static class WinLogonHelper     {         /// <summary>         /// 模拟windows登录域         /// http://www.cnblogs.com/yukaizhao/         /// </summary>         [DllImport("advapi32.DLL", SetLastError = true)]         public static extern int LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);     }       class Program     {         static void Main(string[] args)         {             IntPtr admin_token = default(IntPtr);             WindowsIdentity wid_admin = null;             WindowsImpersonationContext wic = null;               //在程序中模拟域帐户登录             if (WinLogonHelper.LogonUser("uid", "serverdomain", "pwd", 9, 0, ref admin_token) != 0)             {                 using (wid_admin = new WindowsIdentity(admin_token))                 {                     using (wic = wid_admin.Impersonate())                     {                         //假定要操作的文件路径是10.0.250.11上的d:\txt.txt文件可以这样操作                         FileInfo file = new FileInfo(@"\\10.0.250.11\d$\txt.txt");                         //想做什么操作就可以做了                     }                 }             }         }     } }

模拟域帐户之后，就有了模拟用户的权限，这里千万要注意安全！
