How to call a REST API using C#

Use HttpClient to make REST API calls and other type of requests.
Below is the code for making a request.


static void Main(string[] args)
{
    using var client = new HttpClient();
    client.BaseAddress = new Uri(url);

    // Add an Accept header for JSON format.

    client.DefaultRequestHeaders.Accept.Add(
       new MediaTypeWithQualityHeaderValue("application/json"));

    // Get data response

    var response = client.GetAsync(urlParameters).Result;  
    if (response.IsSuccessStatusCode)
    {
        // Parse the response body

        var dataObjects = response.Content
                       .ReadAsAsync<IEnumerable<DataObject>>().Result;  
        foreach (var d in dataObjects)
        {
            Console.WriteLine("{0}", d.Name);
        }
    }
    else
    {
        Console.WriteLine("{0} ({1})", (int)response.StatusCode,
                      response.ReasonPhrase);
    }
}
