????????????bytes?=?new?byte[lb.Count];
????????????lb.CopyTo(bytes);
????????????//chars?=?new?char[en.GetCharCount(bytes,?0,?bytes.Length)];
????????????//en.GetChars(bytes,?0,?bytes.Length,?chars,?0);
????????????//rs?=?new?string(chars);
????????????rs?=?en.GetString(bytes);

其實可以只用一句話:

rs?=?HttpUtility.UrlDecode(value);
