可以用c#枚举出操作系统上所有的用户吗？

using System;
using System.Diagnostics;
using System.Text.RegularExpressions;

namespace c2
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] users = Regex.Split(Regex.Match(runcmd("net user"), @"(?<=-\s)[\w\s]+(?=命令成功完成)").Value.Trim(), @"\s+");

            foreach (string u in users)
            Console.WriteLine(u);
            Console.ReadKey();
        }

        private static string runcmd(string command)
        {
            Process p = new Process();
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.Arguments = "/c " + command;
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;
            p.Start();
            return p.StandardOutput.ReadToEnd();
        }
    }
}
