URL string generation in .NET

I was wondering if .NET had any class used to ease URL generation, similar to Path.Combine but for URLs.

Example of functionality I'm looking for:

string url = ClassName.Combine("http://www.google.com", "index")
            .AddQueryParam("search", "hello world").AddQueryParam("pagenum", 3);
// Result: http://www.google.com/index?search=hello%20world&pagenum=3

// In webform code behind: 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Collections.Specialized;

namespace testURL
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            NameValueCollection queryString = System.Web.HttpUtility.ParseQueryString(string.Empty);

            queryString["firstKey"] = "a";
            queryString["SecondKey"] = "b";

            string url=GenerateURL(queryString); // call function to get the url
        }

        private string GenerateURL(NameValueCollection nvc)
        {
            return "index.aspx?" + string.Join("&", Array.ConvertAll(nvc.AllKeys, key => string.Format("{0}={1}", HttpUtility.UrlEncode(key), HttpUtility.UrlEncode(nvc[key]))));
        }

    }
}
