Using Invoke to access object in a windows forms/controls thread

Using asynchronous programming might be helpful in making the user’s experience better. Asynchronous programming basically includes processing of a heavy operation into a separate thread to avoid the UI freezing and letting the user to perform other operations parallely.

In a windows application whenever you try to access a windows forms or controls object from a different thread then you won’t be able to do. To handle such kind to scenario, you can use Invoke to access a cross thread object

Suppose you have a function in you form which you want call from a separate thread.

First of all you need to create a delegate with matching signature of this function

Now to call this function from a separate thread use Invoke method with parameters

If you are not sure whether it will be called from a different thread, you can check whether invoke is required.
