Asmx service return json data instead of xml

Question

I have asmx service & when on browser i run url. at that time i am getting xml + json response.

my service code:

namespace CTSWebApp.Service
{
    /// <summary>
    /// Summary description for GetShipperConsignee
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [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 GetShipperConsignee : System.Web.Services.WebService
    {
        [WebMethod]
        [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
        public string GetAutoList(string SearchText)
        {
            List<ShipperDTO> shipperList = new List<ShipperDTO>();
            ShipperApp shipperApp = new ShipperApp();
            shipperList = shipperApp.GetShipper(SearchText);

            var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
            string m_json =  serializer.Serialize(shipperList);

            return  m_json;

        }
    }
}

Now, when i run url on browser. My response is:

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">List :[{"VendorId":18,"Name":"GRIP RITE","Address1":"530B NE 42ND COURT","Address2":"","State":"FL","City":"FT LAUDERDALE","Zip":"33334"},{"VendorId":1003895,"Name":"GRIP RITE","Address1":"214-A BICKLEY RD","Address2":"","State":"SC","City":"LEXINGTON","Zip":"29072"},{"VendorId":1009453,"Name":"GRIFFIN PLATING CO","Address1":"1636 WEST ARMITAGE AVE.","Address2":"","State":"IL","City":"CHICAGO","Zip":"60622"},{"VendorId":1012716,"Name":"GRIFFIN TRANSPORT SERVICE","Address1":"5360 CAPITAL COURT","Address2":"STE 100","State":"NV","City":"RENO","Zip":"89502"},{"VendorId":1016190,"Name":"GRIFFIN GREENHOUSE","Address1":"7141 OLD RUTLEDGE PIKE","Address2":"","State":"TN","City":"KNOXVILLE","Zip":"37924"},{"VendorId":1016668,"Name":"GRIOT\u0027S GARAGE INC","Address1":"3333 S 38TH STREET","Address2":"","State":"WA","City":"TACOMA","Zip":"98409"},{"VendorId":1017354,"Name":"GRIFFIN EXPRESS","Address1":"12 CRESCENT STREET","Address2":"","State":"MA","City":"HOLYOKE","Zip":"01040"},{"VendorId":1018691,"Name":"GRIFFIN INDUSTRIES","Address1":"1001 ORIENT ROAD","Address2":"","State":"FL","City":"TAMPA","Zip":"33619"},{"VendorId":1022522,"Name":"GRIND LAP SERVICES","Address1":"1045 WEST NATIONAL","Address2":"","State":"IL","City":"ADDISON","Zip":"60101"},{"VendorId":1022552,"Name":"GRISWOLD CORPORATION","Address1":"ONE RIVER STREET","Address2":"","State":"CT","City":"MOOSUP","Zip":"06354"},{"VendorId":1027089,"Name":"GRIGNARD COMPANY","Address1":"505 CAPOBIANCO PLAZA BLDG","Address2":"","State":"NJ","City":"RAHWAY","Zip":"07065"}]</string>

also i add code on config file.

<httpHandlers>
      <remove verb="*" path="*.asmx"/>
      <add verb="*" path="*.asmx" type="System.Web.Script.Services.ScriptHandlerFactory" validate="false"/>
    </httpHandlers>

i think. i done everything what required to get json response. also i checked on Internet but they all are same way which i done.

Kindly let me know. what i am making wrong.

Thanks

There is no problem with the code. But do you need this to be accessible via browser's address bar or via ajax' script? By default, browser sends Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 in HttpRequest when you open page in window. That's why you see this.

If you use jQuery then depending on 'datatype' parameter you'll get what you want http://api.jquery.com/jQuery.ajax. Something like:

        $.ajax({
                 type: "get",
                 url: "Sample.asmx/HelloWorld",

                 contentType: "application/json; charset=utf-8",
                 dataType: "json"

             }).done(function(msg){alert(msg.d);});

Otherwise see how Accept http header works https://developer.mozilla.org/en-US/docs/Web/HTTP/Content_negotiation.
