问题
I have a TransactionScope (over DTC, read committed) with a timeout of 60 minutes. In the TransactionScope I have opened the connection (I hope to enlist in the transaction) but after 30 seconds I get a timeout.
In the machine.config I changed the system.transaction maxTimeout to 60 minutes.
Why does the timeout occur after 30 seconds?
回答1:
A SqlCommand already has a CommandTimeout property that defaults to 30 seconds. May be you are using it within your transaction.
