Try this:
string requestURL = "Yourapiurl?name='test'&Id=123&departid=456";
            HttpWebResponse webResponse;
            StreamReader sr = null;
            string returnResponseText = string.Empty;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestURL);
            request.Headers.Add("your header key", "value of key");
            request.Accept = "application/json";
            request.Method = "PUT";
            request.ContentType = "application/json";
List modelllist= new List
//bind data to modellist
var data = Newtonsoft.Json.JsonConvert.SerializeObject(modelllist);
            byte[] bytes = Encoding.ASCII.GetBytes(data);

            request.ContentLength = bytes.Length;
            using (var stream = request.GetRequestStream())
            {
                stream.Write(bytes, 0, bytes.Length);
            }
            webResponse = (HttpWebResponse)request.GetResponse();
            sr = new StreamReader(webResponse.GetResponseStream());
            returnResponseText = sr.ReadToEnd();
