I'm currently using Microsoft SQL Server 2008.

My production server has a very heavy load.

My C# application uses 'SqlDependency' class in order to monitor some table changes.

On development environment - the application works fine, and the change events from the SQL server gets fired correctly.

On production environment - the application gets change events even when there wasn't any change. I have read that the 'SqlDependency' doesn't perform well on heavy load.

I'm looking for other solution to this scenario, any suggestions ?

如果您在没有更改时收到通知，则意味着其他事情触发了通知。您必须始终检查处理程序SqlNotificationEventArgs收到的参数，并OnChange根据 , 和 做出适当 Info的Source反应Type。在生产中，您很可能会收到通知，例如Info.Options表示不正确的 SET 选项（即特定于环境的问题）。

至于关于SqlDependency负载不足的评论，您必须链接源。但是查询通知总体上是针对很少更改的数据的缓存失效而设计的。
