How do I cancel a running task by pressing Enter key in console?

Suppose an application has a method name PrintAsterisk() that prints asterisks on a screen continuously. The method runs on a Task separate from the user interface. I need to ensure that the application stop printing the asterisk on screen when the user presses the Enter key.

How do I cancel a running task by pressing Enter key in console?

Below is the my method that is simplified:

static void PrintAsterisk() {
    while (true) {
        Thread.Sleep(1000);
        Console.Write("*");
    }
}

Depends on how you create a thread, you can pass CancellationToken to it. Inside method ran in the thread just check if that token has cancellation request an break your method if so.
