How to Fix: Asynchronously wait for Task<T> to complete with timeout

Use Task.ContinueWith with a timeout to asynchronously wait for a task to complete and request cancellation if necessary.

Quick Answer: Use Task.ContinueWith with a timeout, such as Task.Delay, to check the status of the task and request cancellation after a certain period.

To asynchronously wait for a Task<T> to complete with timeout, you can use the Task.ContinueWith method in combination with the CancellationToken class.

✅ Solution

Example Code:

var task = new Task(() => { /* your code here */ }); var cancellationTokenSource = new CancellationTokenSource(1000); // 1 second timeout var continuation = task.ContinueWith(t => { if (!cancellationTokenSource.IsCancellationRequested) { /* handle completed task */ } else { /* request cancellation */ } }, cancellationTokenSource.Token);

💡 Explanation

In this example, we create a new Task and a CancellationTokenSource with a 1-second timeout. We then use the ContinueWith method to specify an action that will be executed when the task completes or is cancelled. If the task completes within the specified timeout, the continuation will handle the completed task. If the task is cancelled before completing, the continuation will request cancellation.

💡 Conclusion

By using Task.ContinueWith with a CancellationTokenSource, you can asynchronously wait for a Task<T> to complete with timeout and handle cancellation requests.
