  private static string escape(string s)
  {
   StringBuilder sb = new StringBuilder();
   byte[] ba = System.Text.Encoding.Unicode.GetBytes(s);
   for (int i = 0; i < ba.Length; i += 2)
   {    /**///// BE SURE 2's
    sb.Append("%u");
    sb.Append(ba[i + 1].ToString("X2"));
    sb.Append(ba[i].ToString("X2"));
   }
   return sb.ToString();
           
  }
 

如果是unescape就可以用System.Web.HttpUtility.UrlDecode()方法
