Watching a table in sql server using c#

Question

I need to know if a new record has been added to a particular table in my windows application. Table might be manipulated by different applications.

For now I'm using a Timer control and querying to see if there is a new record (I add record content somewhere in my application and delete record to avoid getting duplicate record), but of course this is not a clean way for this purpose.

Is there something like an event or something better than my approach?

I'm using entity framework 6

Update : I've read about SqlDependency but I don't know if it can be implemented using entity framework

Answer 1

您可以尝试Linq2Cache尝试利用SqlDependency，这是我上次听说EF6已清理其行为 ，现在制定了与Query Notifications兼容的查询 。

Answer 2

Here's an existing StackOverflow article about that using the SQLDependency class .

Alternatively, you can cache the last record ID in memory/local to your program (in a file) or write the last processed record ID to a database table and search for anything more recent than that.
