如何在c#程序中模拟域帐户进行登录操作

代码加注释：

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！
