        string requestBody = $"{{\"location\": {{\"placeId\": \"{placeId}\"}}, \"text\": \"{reviewText}\", \"rating\": {rating}}}";

        // Create the HTTP request
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);

        }

        // Get the HTTP response
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        // Check if the response was successful (HTTP status code 200-299)
        if ((int)response.StatusCode >= 200 && (int)response.StatusCode <= 299) {
            Console.WriteLine("Review posted successfully!");
        } else {
            Console.WriteLine("Error posting review: " + response.StatusCode);
        }
    }
}

To use this code, you can create a new instance of the GoogleReviewPoster class and call the PostReview method, passing in the Google Place ID of the location you want to review, the text of your review, and a rating between 1 and 5. For example: 

GoogleReviewPoster reviewPoster = new GoogleReviewPoster();
string placeId = "ChIJrTLr-GyuEmsRBfy61i59si0"; // Example place ID for the Eiffel Tower in Paris
string reviewText = "I had a great time visiting the Eiffel Tower!";
int rating = 5;
reviewPoster.PostReview(placeId, reviewText, rating);

Note that in order to use this code, you will need to obtain an API key for the Google Maps Places API and include it in your requests. You can find more information on how to obtain an API key and use the Places API in the official Google documentation.
