.Net解析json数组并获取指定的值

string jsonstr="[{"name":"abcd","url":"http://www.aaa.com"},{"name":"12345","url":"http://bbb.com"}]";

JArray json = (JArray)JsonConvert.DeserializeObject(jsonstr);
                    for (int i = 0; i < json.Count; i++)
                    {
                        string v = json[i]["name"].ToString();
                    }
