域是域，局域网是局域网，切勿混淆RT，求具体代码

Answer 1

DirectoryEntry entry = new DirectoryEntry("LDAP://CN=users,DC=fabrikam,DC=com");
DirectorySearcher mySearcher = new DirectorySearcher(entry);
mySearcher.Filter = "(&(objectClass=user)(anr=test*))";
SearchResultCollection ResEnt = mySearcher.FindAll();
{
// Handle results.
}
// Handle exceptions.

Answer 2

            if (runcmd("net user /DOMAIN").IndexOf("nattystyle") >= 0)
                Console.WriteLine("Has user");
            else
                Console.WriteLine("No user");没有域环境,你试试.不行算我没说.        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();
        }
