c#中的异步触发和遗忘

Question

Currently I am about to develop logging for ac# application into a SQL server table.

I have a designated class called Logger that has a static method writeToLog() .

I just want to call that static function without block the calling thread.

How is this possible in C# clean and fast?

The functions don't return anything they are just fire and forget.

Thanks for you advice

Answer 1

There is the chance that the serveral available logging libraries out there have spent some thoughts about performance.

If you still need to develop a light weight solution yourself I think of two ways.

1.) Create a Task that runs the logging function, without awaiting them

2.) The Log-Method saves the Log-Information in a queue that is written to the SQL-database with a background thread.

I would recommend the second way, because the logging itself can be done in a synchronous function call without the Task creation overhead.

Another argument for this approach is that it is possible to gurantee the order of log messages. By using a Task for each single message the order of execution is not defined.

And a last argument: It might be more performant to write blocks of messages to the SQL table. By using the queue you will be able write messages in a bulk operation.
