Error in asp.net webservice

Question

My asmx webservice is like this

   using System;
using System.Collections.Generic;
using System.Data;
using System.Web;
using System.Web.Script.Services;
using System.Web.Services;
using Newtonsoft.Json;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class GetRateRequestData : WebService
{
    [WebMethod]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public string GetParcelLookupData()
    {

            return JsonConvert.SerializeObject(dataSet, Formatting.Indented);

    }
}

And I am trying to access the data in browser like this

http://localhost:53569/services/GetRateRequestData.asmx/GetParcelLookupData/

But this throws an error like

    System.InvalidOperationException: GetParcelLookupData/ Web Service method name is not valid.
   at System.Web.Services.Protocols.HttpServerProtocol.Initialize()
   at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)

I am new to webservices, Can any one point out what I am doing wrong here?

@SainPradeep Actually It was public from the beginning , I just pasted the wrong code here. So yes, the error is same — None

You can decorate your method to allow HTTP GET requests

[WebMethod]  
[ScriptMethod(UseHttpGet=true)]
public string MyMethod(int myint)
{
    // ... code here
}

and change your config as below

<system.web>
<webServices>
  <protocols>
    <add name="HttpGet"/>
</protocols>
</webServices>
