WindowsService中OnStart（）内部的代码段是否重复？

Question

I learnt that the WindowsService`s OnStart() executes the segment of code inside it? Does the segment of code execute only once, which is at the start of process or does it get executed repeatedly until the process stops?

Answer 1

It runs once, and you have to return from it before your service is considered to be started - so if you want something to run continuously, it's up to you to create eg new threads or timers to run that code.

You would also, usually, at this time also set up any needed synchronization primitives (such as ManualResetEvent , or a CancellationTokenSource ) so that you can use these inside your OnStop method to get your new threads/other code to exit gracefully.
