C#后台解析json

JObject jo = (JObject)JsonConvert.DeserializeObject(json);//重要部分
                    int num = jo["res"].Count();
                    string sitename = "";//存到site_rank
                    for (int j = 0; j < num; j++)
                    {
                        int c_3 = 0;
                        int c_5 = 0;
                        int c_10 = 0;
                        int c_30 = 0;
                        int c_50 = 0;
                        if (jo["res"][j].ToString() == "")
                        {
                            continue;
                        }
                        string keyword = dt_keyword.Rows[m]["name"].ToString();
                        string landing = jo["res"][j]["landing"].ToString();
                        string landing_site = landing.Split('/')[0];
                        string rank = jo["res"][j]["rank"].ToString();
}
这里只提供一个简单的例子，自己可以动态去运用
