NetworkStream.Writeable Özellik

protected:
 property bool Writeable { bool get(); void set(bool value); };

protected bool Writeable { get; set; }

member this.Writeable : bool with get, set

Protected Property Writeable As Boolean

Özellik Değeri

true akışa veri yazılabilirse; aksi takdirde , false. true varsayılan değerdir.

Açıklamalar

özelliğini kullanmak için sınıfından NetworkStreamWriteable türetmelisiniz. ise Writeabletrueyöntemine NetworkStream yapılan çağrılara Write izin verir. Ayrıca, genel olarak erişilebilen CanWrite özelliği denetleyerek yazılabilir NetworkStream olup olmadığını belirleyebilirsiniz.

Writeable özelliği başlatıldığında ayarlanırNetworkStream.
