What is BeginInvoke?

What is BeginInvoke?

What is the difference between Invoke and BeginInvoke method in C#?

Invoke: Executes on the UI thread, but calling thread waits for completion before continuing. BeginInvoke: Executes on the UI thread, and calling thread doesn’t wait for completion.

How do you call a code behind asynchronously?

The simplest way to execute a method asynchronously is to start executing the method by calling the delegate’s BeginInvoke method, do some work on the main thread, and then call the delegate’s EndInvoke method. EndInvoke might block the calling thread because it does not return until the asynchronous call completes.

What is MethodInvoker in C#?

What is delegate C#?

When you instantiate a delegate, you can associate its instance with any method with a compatible signature and return type. In other words, a method must have the same return type as the delegate.
