使用.Net获取域中的计算机列表

如何使用C#获取域中的计算机名列表？

using System.DirectoryServices;

public void PrintComputersInDomain (string domainName)
{
    DirectoryEntry de = new DirectoryEntry ("LDAP://" + domainName);
    de.Children.SchemaFilter.Add ("computer");
    foreach (DirectoryEntry c in de.Children)
    {
        Console.WriteLine (c.Name);
    }
}
