Getting null if post Json Serializable object array

Question

i am sending data using HttpClient like below

using (var streamWriter = new StreamWriter(request.GetRequestStream()))                 {                    streamWriter.Write(JsonConvert.SerializeObject(message).ToArray());                 }

by using ToArray() entire message converted to character array

what would be the web api controller method parameter

i am going to use like below

public IHttpActionResult ReceivedMessages([FromBody] Queue<Message> messages)

I have tried char[] array and string[] array also. i am getting null value always. But if i checked this request.Content.ReadAsStringAsync().Result i am receiving the value in string format but in controller class i am getting null

Need following changes: 1. Do not use charArray() 2. Use proper http method as POST 3. Not to use Queue because it may not automatically converts to objects in WebAPI. So better to use List and if requires assign them back to Queue. var webAddr = http://Api/url ; var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr); httpWebRequest.ContentType = application/json; charset=utf-8 ; httpWebRequest.Method = POST ; using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) { string json = sonConvert.SerializeObject(message); //{\x\:	rue\}; streamWriter.Write(json); streamWriter.Flush(); } var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) { var result = streamReader.ReadToEnd(); return result; }

Hi streamWriter.Write(JsonConvert.SerializeObject(message).ToArray()); This line will convert your message into Array of character. Actually what do you want to achieve As per my understanding you want to convert your message into Message class.If you want to convert that firstly you need to Deserialize that object like JsonConvert.DeserializeObject (message);
