I am new to JSON and need help. I have some JSON working in jquery and get the information back correctly from the web service I have running on the web. However, I can't get it to work using HttpWebRequest in C#. I will post the code below.
/// <summary>
/// Summary description for VBRService
/// </summary>
[WebService(Namespace = "http://test.visitblueridge.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
[System.Web.Script.Services.ScriptService]
public class VBRService : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string callJson(string x)
{
return "Worked =" + x;
}
}
That is on the web service and I want to be able to call "callJson(string x)" using this code,
var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{\"x\":\"true\"}";
streamWriter.Write(json);
streamWriter.Flush();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
return result;
}
I keep getting an internal server error. When I change the type to application/json and add,
request.Headers.Add("SOAPAction", "http://test.visitblueridge.com/callJson");
I get an unaccepted media error.
Thank you in advance and hope this helps others.

First of all you missed ScriptService attribute to add in webservice.
After then try following method to call webservice via JSON.
