.net – 在SQL中什么是默认的最大事务超时

如果machine.config上没有“system.transactions”元素,则maxTimeout的machine.config中的默认值是什么(参见示例)？

<system.transactions>
   <machineSettings maxTimeout="??:??:??" />
</system.transactions>

我问这个是因为代码因以下异常而崩溃,似乎它与超时超时的事务有关,它在SaveChanges方法期间崩溃,我收到的异常如下：

The transaction associated with the current connection has completed
but has not been disposed. The transaction must be disposed before
the connection can be used to execute SQL statements.

这是崩溃的代码片段：

using (TransactionScope transaction = TransactionHelper.CreateTransactionScope())
{
    using (EFContext efDBContext = new EFContext())
    {
        try
        {
            efDBContext.Connection.Open();  

            foreach (MyEntity currentEntity in myEntities)
            {
                //Insertion
            }

            transaction.Complete();
        }
        catch (Exception ex)
        {
            //Inspect current entity
            //Get Total Time of the run
            //Number of entities processed
        }
        finally
        {
            if (esfDBContext.Connection.State == ConnectionState.Open)
                esfDBContext.Connection.Close();
        }
    }
}

这是我创建TransactionScope的方法：

public static TransactionScope CreateTransactionScope(TransactionScopeOption option = TransactionScopeOption.Required,IsolationLevel isolationLevel = IsolationLevel.ReadCommitted)
{
    var transactionOptions = new TransactionOptions()
    {
        Timeout = TimeSpan.MaxValue,IsolationLevel = isolationLevel
    };

    return new TransactionScope(option,transactionOptions);
}

解决方法
