IPInterfaceProperties.IsDynamicDnsEnabled 屬性

定義

命名空間:

System.Net.NetworkInformation

組件:

System.Net.NetworkInformation.dll

取得 Boolean 值，指出這個介面是否設定成自動向網域名稱系統 (DNS) 註冊其 IP 位址資訊。

public:
 abstract property bool IsDynamicDnsEnabled { bool get(); };

[System.Runtime.Versioning.SupportedOSPlatform("windows")]
public abstract bool IsDynamicDnsEnabled { get; }

[<System.Runtime.Versioning.SupportedOSPlatform("windows")>]
member this.IsDynamicDnsEnabled : bool

Public MustOverride ReadOnly Property IsDynamicDnsEnabled As Boolean

屬性值

Boolean

如果這個介面已經設定成自動註冊其動態 IP 位址與靜態網域名稱之間的對應，則為 true，否則為 false。

屬性

SupportedOSPlatformAttribute

範例

下列程式代碼範例會顯示此屬性的值。

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

動態 DNS 可讓用戶端通知 DNS 伺服器其動態 IP 位址對應至其靜態主機名。
