Would System.Net.Dns class help you?

If you can help to show me the proper method or property of this class, I
would be grateful. I make a heavy use of Dns class and didn't find any way
to get the nameserver name.

Oh.. Sorry, I was thinking you wanted the services of Dns and not the
name. If you have enough privileges, you can check the
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters"'s
"NameServer" string.

You can use the System.Management methods:

class GetDNS
{
public static void Main()
{
ManagementObjectSearcher mos = new ManagementObjectSearcher(
"SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = 'TRUE'");
ManagementObjectCollection moc = mos.Get();
foreach(ManagementObject mo in moc)
{
Console.WriteLine("Network Card: {0}", mo["Description"]);
string[] hosts = (string[])mo["DNSServerSearchOrder"];
foreach(string host in hosts)
Console.WriteLine(" DNS host: {0}",host);
}
}
}

Hope this helps some.
