In this example, we're making a POST request to create a new post on a fake API. The `Post` object is defined elsewhere in the code and contains properties for `Title`, `Body`, and `UserId`. We use `AddObject` to include the `Post` object in the request body. The response is stored in an `IRestResponse` variable. Another example:csharp var client = new RestClient("https://someapi.com/users"); var request = new RestRequest(Method.POST); var user = new User { Name = "John", Age = 27, Email = "[email protected]" }; request.AddObject(user); IRestResponse response = client.Execute(request); ``` In this example, we're creating a new user on another API. The `User` object is defined elsewhere and contains properties for `Name`, `Age`, and `Email`. We use `AddObject` to include the `User` object in the request body. In both examples, we're using the RestSharp package to make API calls and the `AddObject` method to add objects to the request body.
