.net 如何阻止SqlBulkCopy.WriteToServer尝试使用MSDTC（分布式事务协调器）

我的代码非常简单。我真的不知道为什么会这样。我不确定事务范围或任何东西。我只是尝试将数据大容量复制到我的数据库中

using (SqlBulkCopy bulkCopy = new SqlBulkCopy(MyConnectionString))
        {
            bulkCopy.DestinationTableName = "TableName";                
            bulkCopy.ColumnMappings.Add("Column1", "Column1");
            ...
            bulkCopy.BatchSize = 1000;

            bulkCopy.WriteToServer(someDataSet);
        }

当我运行时，我有时会得到以下信息。我不希望SqlBulCopy内部事务得到提升或类似的东西。这应该是一个简单的批量插入。设置批量大小是否会强制升级

嗯，您正在使用TransactionScope。当它升级到MSDTC时进行研究。或者发布更多代码。您如何判断我正在使用事务范围。堆栈跟踪中是否有任何提示？System.Transactions是我所知道的实现DTC事务的唯一方法。您也可以使用事务类，但这是不寻常的。可能其他组件正在设置作用域（一些消息总线会这样做）。检查

事务。当前

。它是非空的吗？usr，你是对的。我使用的是代码中较高的某个事务范围。如果你把你的评论合并成一个答案，我可以接受。我也可以删除我的问题，但不确定这样做是否正确。
