OperationBehaviorAttribute.TransactionAutoComplete 속성

정의

네임스페이스:

System.ServiceModel

어셈블리:

System.ServiceModel.dll

처리되지 않은 예외가 발생하지 않을 때 현재 트랜잭션 범위를 자동으로 완료할지 여부를 나타내는 값을 가져오거나 설정합니다.

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

속성 값

Boolean

작업을 성공적으로 실행했을 때 트랜잭션 범위를 자동으로 완료하려면 true이고, 그렇지 않으면 false입니다. 기본값은 true입니다.

예제

다음 코드 예제에서는 필수 분산 트랜잭션 내에서 실행되는 작업을 보여 줍니다. TransactionScopeRequired 속성은 작업이 트랜잭션 범위에서 실행됨을 나타내며, TransactionAutoComplete 속성은 처리되지 않은 예외가 발생하지 않을 경우 트랜잭션 범위가 자동으로 완료됨을 나타냅니다. 처리되지 않은 예외가 발생하면 트랜잭션은 중단됩니다.

설명

작업 코드에서 직접 트랜잭션을 완료하거나 중단하려면 TransactionAutoComplete 속성을 false로 설정합니다.

처리된 예외는 작업 과정에서 트랜잭션 자동 중단 없이 throw할 수 있습니다. 처리되지 않은 예외가 있을 때만 자동 중단이 발생합니다.
