Need to run a function just before the syatem shutdown in C# Windows application

Question

I am working on c# windows application. I have a requirement to do to run a certain task if system shutdown or restarts.
Please suggest if we can trap the system shutdown event just before happening?

Hi @Sachin Kumar ,Welcome to Q&A.

This is possible, you need to refer to WM_QUERYENDSESSION message and SystemEvents.SessionEnding Event.

You can also Use OnShutdown to specify the processing that occurs when the system shuts down.

This following case can give a good example of your problem.
