如何使用c#代码重命名Windows Guest帐户

static void Main(string[] args)
{
DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName +     ",Computer");
DirectoryEntry admGroup = localMachine.Children.Find("Users");
object members = admGroup.Invoke("members", null);
foreach (object groupMember in (IEnumerable)members)
DirectoryEntry member = new DirectoryEntry(groupMember);
Console.WriteLine(member.Name);                
Console.ReadLine();
}

在输出中，我得到了"Users"下的本地帐户列表。
