怎么把Json数组中Unicode转换为汉字

[zkj513703929]

{events:[{"timestamp":"20130520T171624\u002E937\u002B0800","parameters":[{"value":26617637,"type":"PROCESSING\u005FTIME"}]}

 public string ToGB2312(string str)
    {

        string r = "";

        MatchCollection mc = Regex.Matches(str, @"\\u([\w]{2})([\w]{2})", RegexOptions.Compiled | RegexOptions.IgnoreCase);

        byte[] bts = new byte[2];

        foreach (Match m in mc)
        {

            bts[0] = (byte)int.Parse(m.Groups[2].Value, NumberStyles.HexNumber);

            bts[1] = (byte)int.Parse(m.Groups[1].Value, NumberStyles.HexNumber);

            r += Encoding.Unicode.GetString(bts);

        }

        return r;

    }

这种转换不成功！

Regex.Unescape(你要转的Unicode字符串)

直接转就行了 但是，最后要把结果最外层的两个大括号去掉 前几天写的例子 你可以看看http://download.csdn.net/detail/huangchao2011/5394463
