範例

以下程式碼範例顯示本地電腦網路介面的網域名稱服務（DNS）位址。

public static void DisplayDnsAddresses()
{
    NetworkInterface[] adapters  = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {

        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        IPAddressCollection dnsServers = adapterProperties.DnsAddresses;
        if (dnsServers.Count > 0)
        {
            Console.WriteLine(adapter.Description);
            foreach (IPAddress dns in dnsServers)
            {
                Console.WriteLine("  DNS Servers ............................. : {0}",
                    dns.ToString());
            }
            Console.WriteLine();
        }
    }
}

Public Shared Sub DisplayDnsAddresses() 
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        
        Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
        Dim dnsServers As IPAddressCollection = adapterProperties.DnsAddresses
        If dnsServers.Count > 0 Then
            Console.WriteLine(adapter.Description)
            Dim dns As IPAddress
            For Each dns In  dnsServers
                Console.WriteLine("  DNS Servers ............................. : {0}",dns.ToString() )
            Next dns
        End If
    Next adapter

End Sub

你不會建立這個類別的實例;實例由類別中 IPInterfaceProperties 的方法回傳。
