C＃，transactionScope内部的SQL SP通过超时来结束事务

Question

With the code:

using (TransactionScope scope = new TransactionScope( TransactionScopeOption.RequiresNew, new System.TimeSpan( 0, 15, 0 ) ))
    {
      try
      {
        for (int i=0; i<10000; i++)
        {
          dataContext.CallSP( i );
        }
      }
      catch (Exception e)
      {
        log( e );
      }
      finally
      {
        scope.Complete();
      }
    }

If we call CallSP, it may time out. If it times out, we get the error when trying to Complete() the transaction.

The transaction has aborted. | System.Data.SqlClient.SqlException (0x80131904): The COMMIT TRANSACTION request has no corresponding BEGIN TRANSACTION.

What is a way to structure this, so that we keep the speedup benefit of running the CallSPs in a transaction, and we don't try to complete it, if the CallSP failed in such a way that the transaction is no longer open for Completing?

Answer 1

Rather than calling scope.Complete() in the finally{} clause, call it in the try{} clause.

using (TransactionScope scope = new TransactionScope(TransactionScopeOption.RequiresNew, new System.TimeSpan( 0, 15, 0 ) ))
    {
      try
      {
        for (int i=0; i<10000; i++)
        {
          dataContext.CallSP( i );
        }
        scope.Complete();
      }
      catch (Exception e)
      {
        log( e );
      }
    }

The TransactionScope will automatically abort if you enter the catch{} clause and therefore do not call scope.Complete() before exiting the using{} clause..
