如何在Windows Mobile上解码url编码字符串？

using System;
using System.Web;

namespace UrlDecodeExample
{
    class Program
    {
        static void Main(string[] args)
        {
            string encodedUrl = "https%3A%2F%2Fwww.example.com%2F%3Fsearch%3Dtest";
            string decodedUrl = HttpUtility.UrlDecode(encodedUrl);
            Console.WriteLine("Encoded URL: " + encodedUrl);
            Console.WriteLine("Decoded URL: " + decodedUrl);
        }
    }
}
