Tanım

Ad Alanı:

System.Net.NetworkInformation

Bütünleştirilmiş Kod:

System.Net.NetworkInformation.dll

Bu arabirimin paketleri iletip iletemeyeceğini (yönlendirebileceğini) belirten bir Boolean değer alır.

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

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

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

Public MustOverride ReadOnly Property IsForwardingEnabled As Boolean

Özellik Değeri

Boolean

true bu arabirim paketleri yönlendirirse; aksi takdirde false.
