IPInterfaceProperties.DnsSuffix 屬性

定義

命名空間:

System.Net.NetworkInformation

組件:

System.Net.NetworkInformation.dll

取得與這個介面關聯的網域名稱系統 (DNS) 尾碼。

public:
 abstract property System::String ^ DnsSuffix { System::String ^ get(); };

[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
public abstract string DnsSuffix { get; }

[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
member this.DnsSuffix : string

Public MustOverride ReadOnly Property DnsSuffix As String

屬性值

String

String，包含這個介面的 DNS 尾碼，但如果介面沒有 DNS 尾碼則為 Empty。

屬性

UnsupportedOSPlatformAttribute

範例

下列程式代碼範例會顯示 DNS 後綴。

void DisplayDnsConfiguration()
{
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum10 = adapters->GetEnumerator();
   while ( myEnum10->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum10->Current);
      IPInterfaceProperties ^ properties = adapter->GetIPProperties();
      Console::WriteLine( adapter->Description );
      Console::WriteLine( "  DNS suffix................................. :{0}", 
         properties->DnsSuffix );
      Console::WriteLine( "  DNS enabled ............................. : {0}", 
         properties->IsDnsEnabled );
      Console::WriteLine( "  Dynamically configured DNS .............. : {0}", 
         properties->IsDynamicDnsEnabled );
   }
}

public static void DisplayDnsConfiguration()
{
    NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {
        IPInterfaceProperties properties = adapter.GetIPProperties();
        Console.WriteLine(adapter.Description);
        Console.WriteLine("  DNS suffix .............................. : {0}",
            properties.DnsSuffix);
        Console.WriteLine("  DNS enabled ............................. : {0}",
            properties.IsDnsEnabled);
        Console.WriteLine("  Dynamically configured DNS .............. : {0}",
            properties.IsDynamicDnsEnabled);
    }
    Console.WriteLine();
}

Public Shared Sub DisplayDnsConfiguration() 
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        Dim properties As IPInterfaceProperties = adapter.GetIPProperties()
        Console.WriteLine(adapter.Description)
        Console.WriteLine("  DNS suffix................................. :{0}", properties.DnsSuffix)
        Console.WriteLine("  DNS enabled ............................. : {0}", properties.IsDnsEnabled)
        Console.WriteLine("  Dynamically configured DNS .............. : {0}", properties.IsDynamicDnsEnabled)
    Next adapter

End Sub

備註

DNS 後綴會識別功能變數名稱 (，例如附加至未限定主機名的 「contoso.com」) ，以取得適用於 DNS 名稱查詢的完整功能變數名稱 (FQDN) 。 例如，如果本機計算機具有 「contoso.com」 做為其 DnsSuffix，而且必須解析不合格的主機名 「www」 則要查詢的 FQDN 為 「www.contoso.com」。
