josn反序列化解决方法

josn反序列化
请问下大家像这样的json字符串要怎么反序列化成实体对象呢？
"{"right_picture":"a:2:{s:13:"right_pic_url",s:57:"http:\\/\\/www.sinaimg.cn\\/blog\\/miniblog\\/media\\/radio\\/12334.jpg",s:14:"right_link_url",s:49:"http:\\/\\/video.sina.com.cn\\/z\\/weiboradio\\/index.shtml",}"
[解决办法]
using System.Web.Script.Serialization;

 json = json.Trim();
        if (json[0] != '[')
            json = "[" + json;
        if (json[json.Length - 1] != ']')
            json = json + "]";

        JavaScriptSerializer jss = new JavaScriptSerializer();
        ArrayList arrList = jss.Deserialize<ArrayList>(json);
