Hands-On Parallel Programming with C# 8 and .NET Core 3

Using delegate

In the following code, we are creating a task object by calling the Task constructor and passing an anonymous delegate containing the method we want to execute:

Task task = new Task (delegate {PrintNumber10Times ();});task.Start();

In all of these cases, the output will be as follows:

All the preceding methods do the same thing – they just have different syntaxes.

We can only call the Start method on tasks that have not run previously. If you need to rerun a task that has already been completed, you need to create a new task and call the Start method on that.
