尝试将JSON数据发送到服务器时出现语法错误或访问冲突异常

Question

I try to send a JSON data to a server using c#. this is my code for posting data:

 private static string PostJSONData(string JSONdata, Uri url)
    {
        try
        {
            var httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
            httpWebRequest.ContentType = "text/json";
            httpWebRequest.Method = "POST";

            using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
            {
                streamWriter.Write(JSONdata);
                streamWriter.Flush();
                streamWriter.Close();
            }
            var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
            using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
            {
                var result = streamReader.ReadToEnd();
                return result;
            }

        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

my JSON data is like this :

{"Key":"auth_token","Value":""},
{"Key":"request_id","Value":"14104"},
{"Key":"_number","Value":"TAQ422924"},
{"Key":"Customer","Value":"Some Customer"},
{"Key":"first_date","Value":"2014-10-24T15:52:21"}]

when I try to send data, at line

var result = streamReader.ReadToEnd();

there is an error with this description

ContentType for json is "application/json" and not "text/json". The server may be treating you data as text rather than json. You json data is also missing the leading square bracket '['
