HttpResponseOnCompleted

HttpResponseOnCompleted is a method provided by the System.Net.Http.HttpResponseMessage class in .NET. It allows developers to register a callback action that will be executed when the HttpResponseMessage has completed its processing. This completion typically signifies that the entire HTTP response, including its content, has been successfully received and parsed by the client.

The primary use case for HttpResponseOnCompleted is to perform cleanup operations or trigger subsequent actions after the response has been fully processed. For instance, you might use it to release resources that were temporarily allocated for handling the response, such as closing network streams or disposing of temporary data structures. It can also be used to signal the completion of an asynchronous operation that was initiated to fetch the HTTP response.

The method accepts a single parameter, an Action delegate, which represents the code to be executed upon completion. This action is invoked asynchronously after the response content has been read. It's important to note that HttpResponseOnCompleted should be used with caution, as the timing of its execution is tied to the completion of the HTTP response processing. If the response processing is interrupted or fails, the registered callback may not be executed. Developers should ensure that any operations performed within the callback are robust and handle potential errors gracefully.
