未提交的事务隔离级别

Question

我正在尝试使用TransactionScope对象了解事务如何在c＃中工作。我在SQL服务器上了解它们，但我不知道如何在c#中验证这一点。例如，我想检查是否将IsolationLevel设置为ReadUnCommitted，如何在我的代码中验证此行为？

目前这是我的简单代码，我想测试的是在我的第一个Update命令正在执行而未提交/回滚时如何验证其他事务是否能够读取它影响的数据？任何人都可以帮我一个代码示例吗？

这是我的代码：

public void TransferAmount(Account a)
{
    bool debit = false;
    bool credit= true;
    var option = new TransactionOptions();
    option.IsolationLevel = System.Transactions.IsolationLevel.ReadUnCommitted;
    try
    {
        using (TransactionScope transactionScope = new TransactionScope(TransactionScopeOption.Required, option))
        {
            using (IDbCommand cmd = Idbconnection.CreateCommand())
            {
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.CommandText = "usp_Update_Debit";
                IDataParameter param = cmd.CreateParameter();
                param.ParameterName = "@mDebitAmount";
                param.Value = a.Amount;
                cmd.Parameters.Add(param);
                Idbconnection.Open();
                debit = cmd.ExecuteNonQuery() == 1;
            }
            using (IDbCommand cmd = Idbconnection.CreateCommand())
            {
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.CommandText = "usp_Update_Credit";
                IDataParameter param = cmd.CreateParameter();
                param.ParameterName = "@mCreditAmount";
                param.Value = a.Amount;
                cmd.Parameters.Add(param);
                credit = cmd.ExecuteNonQuery() == 1;
            }
            if (debit == credit)
                transactionScope.Complete();
        }
    }
    catch (Exception ex)
    {
        System.ServiceModel.Web.WebOperationContext.Current.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.OK;
        throw new FaultException(new FaultReason(new FaultReasonText(ex.Message)));
    }
}
