[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
public abstract System.Net.NetworkInformation.IPAddressCollection DnsAddresses { get; }

[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
member this.DnsAddresses : System.Net.NetworkInformation.IPAddressCollection

Public MustOverride ReadOnly Property DnsAddresses As IPAddressCollection

プロパティ値

IPAddressCollection

DNS サーバーのアドレスを格納している IPAddressCollection。

属性

UnsupportedOSPlatformAttribute

例

次のコード例では、ローカル コンピューター上のネットワーク インターフェイスの DNS アドレスを表示します。

void DisplayDnsAddresses()
{
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum11 = adapters->GetEnumerator();
   while ( myEnum11->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum11->Current);
      IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
      IPAddressCollection ^ dnsServers = adapterProperties->DnsAddresses;
      if ( dnsServers->Count > 0 )
      {
         Console::WriteLine( adapter->Description );
         System::Collections::IEnumerator^ myEnum12 = dnsServers->GetEnumerator();
         while ( myEnum12->MoveNext() )
         {
            IPAddress ^ dns = safe_cast<IPAddress ^>(myEnum12->Current);
            Console::WriteLine( "  DNS Servers ............................. : {0}", 
               dns->ToString());
         }
      }
   }
}

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);

            {
                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

DNS は、ホスト名を IP アドレスにマップするために使用される階層的な名前付けシステムです。
