Windows安全机制学习笔记（三）--获取当前账户信息

基于.Net Framework 4.0, 使用Windows Identity类可获取当前账户的相关信息，包含账户名称，SID，组成员关系等。代码如下：

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

namespace WindowsSecurityViaCSharp
{
    class Program
    {
        static void Main(string[] args)
        {
            WindowsIdentity winIdentity = WindowsIdentity.GetCurrent();
            if (winIdentity == null)
            {
                Console.WriteLine("Cannot get current user identity. Exiting...");
                return;
            }

            Console.WriteLine("Current machine name:\t" + Environment.MachineName);

            Console.WriteLine("Current user name:\t" + winIdentity.Name);
            Console.WriteLine("Current user authentication type:\t" + winIdentity.AuthenticationType);
            Console.WriteLine("Current user SID:\t" + winIdentity.User);
            Console.WriteLine("Current user token:\t" + winIdentity.Token);
            Console.WriteLine("Token owner SID:\t" + winIdentity.Owner);
            Console.WriteLine("Current user has {0} group memberships.", winIdentity.Groups.Count);
            foreach (IdentityReference  group  in winIdentity.Groups)
            {
                NTAccount ntAcc = (NTAccount)group.Translate(typeof(NTAccount));
                Console.WriteLine("\tGroup {0}", ntAcc.Value);
            }
        }
    }
}
