how to get only json data with webservice

Question

i have create web service :

demo.asmx

<%@ WebService Language="C#" CodeBehind="~/App_Code/demo.cs" Class="demo" %>

demo.cs

public class demo : System.Web.Services.WebService
{


    public demo()
    {

    }

    [WebMethod]

    [ScriptMethod(UseHttpGet = true, XmlSerializeString = false, ResponseFormat = ResponseFormat.Json)]

    public string saveUserData()
    {


        Employee[] emps = new Employee[] {  
            new Employee()  
            {  
                Id=1,  
                Name="xyz" 
            },  
            new Employee()  
            {  
                Id=2,  
                Name="abc" 
            }  
        };

        return new JavaScriptSerializer().Serialize(emps);

    }

}

Now when i run this then it gives me below data:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
      <string>[{"Id":1,"Name":"xyz"},{"Id":2,"Name":"abc"}]</string>

so i have check the console and it gives me the

Cache-Control → private, max-age=0
Content-Encoding → gzip
Content-Length → 232
Content-Type → text/xml; charset=utf-8
Date → Sat, 05 Mar 2016 06:33:53 GMT
Server → Microsoft-IIS/8.0
Vary → Accept-Encoding
X-AspNet-Version → 4.0.30319
X-Powered-By → ASP.NET
X-SourceFiles → =?UTF-8?B?RDpcRGVtb193ZWJz

Its gives content type is text/xml even i have define the Json response format.

How can i get only json response like below ?

[{"Id":1,"Name":"xyz"},{"Id":2,"Name":"abc"}]

You don't manually serialize to JSON in web services. You return the object itself, and the service serializes it to the correct type. Other than that, - — GSerg, Mar 05 '16 at 06:56

@GSerg i am not using any `ajax` in aspx page. this applicaiton doesnt content aspx pages . i am just creating webservices only. — , Mar 05 '16 at 07:01
It does not matter if you are using ajax or not. Do you provide the [correct content-type](http://stackoverflow.com/a/6023810/11683)? — GSerg, Mar 05 '16 at 07:03
@GSerg I have that confusion only. how to pass content type ? because i am just hit the url like - `http://localhost:2079/demo.asmx/saveUserData` . so where i have to define the `content type` ? — , Mar 05 '16 at 07:09
You set content type in whatever thing you are using to fetch data. Most commonly it's ajax. The browser's url bar is not a proper testing tool for web services. You should have a test client for your web service, e.g. as a static html page with jquery that makes ajax calls. — GSerg, Mar 05 '16 at 07:37

you should use the following, Don't serialize manually, just do the following

[WebService(Namespace = "http://example.com/")] 
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]System.Web.Services.WebService
[ScriptService]
public class services :WebService  
{    
    [WebMethod(CacheDuration = 60)]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public List<TestObject> GetObjectCollection()
    {
           return YourService.GetObjectCollection().ToList();
    }
}
