예제

다음 예제에서는 종속 트랜잭션을 만드는 방법을 보여 줍니다.The following example shows you how to create a dependent transaction.

static void Main(string[] args)
{
    try
    {
        using (TransactionScope scope = new TransactionScope())
        {
            // Perform transactional work here.

            //Queue work item
            ThreadPool.QueueUserWorkItem(new WaitCallback(WorkerThread), Transaction.Current.DependentClone(DependentCloneOption.BlockCommitUntilComplete));

            //Display transaction information
            Console.WriteLine("Transaction information:");
            Console.WriteLine("ID:             {0}", Transaction.Current.TransactionInformation.LocalIdentifier);
            Console.WriteLine("status:         {0}", Transaction.Current.TransactionInformation.Status);
            Console.WriteLine("isolationlevel: {0}", Transaction.Current.IsolationLevel);

            //Call Complete on the TransactionScope based on console input

설명

종속 트랜잭션을 복제 된 트랜잭션의 결과에 해당 결과가 종속 트랜잭션입니다.A dependent transaction is a transaction whose outcome depends on the outcome of the transaction from which it was cloned.

cloneoption 매개 변수는 만들 종속 트랜잭션의 종류를 제어 합니다.The cloneoption parameter controls what kind of dependent transaction to create. BlockCommitUntilComplete를 사용 하 여 종속 트랜잭션을 만든 경우 트랜잭션이 시간 초과 되거나 DependentTransaction에서 Complete 호출 될 때까지 트랜잭션의 커밋 프로세스를 차단 합니다.If a dependent transaction is created with BlockCommitUntilComplete, it blocks the commit process of the transaction until the transaction times out, or Complete is called on the DependentTransaction. RollbackIfNotComplete를 사용 하 여 만든 경우 DependentTransaction에서 Complete를 호출 하기 전에 Commit가 호출 되 면 트랜잭션이 자동으로 중단 됩니다.If it is created with RollbackIfNotComplete, it automatically aborts the transaction if Commit is called before Complete is called on the DependentTransaction.
