Answer 1

您可以通过设置SqlCommand.CommandTimeout属性来提高命令的超时时间.

Answer 2

也许这不适用,但我认为应该提到它.默认的CommandTimeOut是30秒.对于99.9%的Web应用程序中发生的任何操作,这应该是充足的时间.除非你绝对确定该操作需要的时间超过这个时间,否则你应该花时间尝试优化sql,使其在<30秒内返回.正确的索引是一个很好的起点.

Answer 3

然后将其添加到连接字符串中:

server={servername};database={dbname};uid={username};pwd={password};Connect Timeout=600
