我得到了:
System.Data.SqlClient.SqlException (0x80131904): Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out

at System.Data.SqlClient.SqlTransaction.Save(String savePointName)
如何增加SqlTransaction.Save()
的超时?
答案 0 :(得分:3)
现在我真的希望我没有鼓励PSVSupporter删除他的答案(如果他取消删除,请投票给他)。
在您发出任何事务请求时,请求会使用基础连接的ConnectionTimeout
属性作为查询的CommandTimeout
。
您可以在源代码中关注此过程,重要的部分在SqlInternalConnectionTds.ExecuteTransactionYukon
和SqlInternalConnectionTds.ExecuteTransactionPreYukon
都将ConnectionOptions.ConnectTimeout
传递到timeout
参数,并调用他们调用的函数。因此,要解决您的问题,请在创建连接时使用更大的ConnectionTimeout
。

//SNIP
_internalTransaction.Save(savePointName);

}
internal void Save(string savePointName) {
//SNIP
_innerConnection.ExecuteTransaction(SqlInternalConnection.TransactionRequest.Save, savePointName, IsolationLevel.Unspecified, null, false);
//SNIP
}
