What are cancellation tokens in programming?
Cancellation tokens are a way to signal that an operation should be canceled, allowing for more responsive applications.
How do I implement cancellation tokens in my code?
You can implement cancellation tokens by using the CancellationToken
class in .NET, for example, to manage task cancellation.
Can you give me an example of using cancellation tokens?
Sure! Here's a simple example: you create a CancellationTokenSource
, pass its token to a task, and call Cancel()
to stop it.
What happens if I don't use cancellation tokens?
Without cancellation tokens, long-running tasks may continue to run even if the user no longer needs the result, wasting resources.
