通过.NET代码的SQL超时

所以我们有一个运行的进程，它调用我们的数据库来获取一些数据。当我们运行通过SQL Server Management Studio调用的proc时，运行需要6分钟到15分钟，但是完成。当我们通过代码运行它时，它总是超时。我的猜测是代码的预期超时范围被超出了，但proc实际上仍然可以运行，因为它直接通过Management Studio界面。通过.NET代码的SQL超时

这里的异常详细信息：

InnerException: System.Data.SqlClient.SqlException 
     Message=Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. 
     Source=.Net SqlClient Data Provider 
     ErrorCode=-2146232060 
     Class=11 
     LineNumber=0 
     Number=-2 
     Procedure="" 
     Server=KSQCOREDBINT 
     State=0

而这里的堆栈跟踪，如果有帮助的所有：

反正我们可以增加分配超时范围还是什么？我们一直致力于改进存储过程，但这取决于数据库团队。只是想看看我能否为我做点什么。

谢谢。

增大[SqlCommand的的的CommandTimeout（http://msdn.microsoft.com /en-us/library/system.data.sqlclient.sqlcommand.commandtimeout.aspx）或将其设置为0（无限制）。 –
