OperationBehaviorAttribute.TransactionAutoComplete Özellik

Tanım

Ad Alanı:

System.ServiceModel

Bütünleştirilmiş Kod:

System.ServiceModel.dll

İşlenmeyen özel durumlar oluşmadığında geçerli işlem kapsamının otomatik olarak tamamlanıp tamamlanmayacağını belirten bir değer alır veya ayarlar.

public:
 property bool TransactionAutoComplete { bool get(); void set(bool value); };

public bool TransactionAutoComplete { get; set; }

member this.TransactionAutoComplete : bool with get, set

Public Property TransactionAutoComplete As Boolean

Özellik Değeri

Boolean

true işlemin başarıyla yürütülmesinde işlem kapsamını otomatik olarak tamamlamak için; aksi takdirde , false. Varsayılan değer: true.

Örnekler

Aşağıdaki kod örneği, zorunlu dağıtılmış bir işlem içinde yürütülen bir işlemi gösterir. TransactionScopeRequired özelliği işlemin bir işlem kapsamı altında yürütüldüğünü, TransactionAutoComplete özelliği ise işlenmeyen özel durum oluşmazsa işlem kapsamının otomatik olarak tamamlandığını gösterir. İşlenmeyen bir özel durum oluşursa işlem durdurulür.

Açıklamalar

TransactionAutoComplete özelliğinifalse, işlemin kodunda doğrudan işlemleri tamamlamak veya durdurmak için olarak ayarlayın.

İşlenen özel durumlar, işlemi otomatik olarak iptal etmeden işlemin seyrinde oluşturulabilir. Yalnızca işlenmeyen özel durumlar otomatik durdurmayı tetikler.
