- Step 1: Use the GetResponseStream method to get the response stream.
Method 2: Check the Status Code Before Calling GetResponse

🎯 Final Words
By following these methods, you can handle HTTP responses with status codes outside the 200-299 range and avoid exceptions. Remember to always check the status code before calling GetResponse to ensure a smooth and reliable experience.
