Question

Just have a normal method like

void DosomethingLong()

What’s the best way to call it in an async way?

Answer 1

The standard way is to create a delegate of the method:

Action myMethod = DosomethingLong;

then execute it asynchronously using the APM (example):

IAsyncResult result = myMethod.BeginInvoke(..., null);

// ...

myMethod.EndInvoke(result);

There are other methods you can use; using a Thread, using BackgroundWorker, etc, depending on your exact requirements.
