不能反序列化当前的JSON对象(例如，{“name”:“value”})进入类型“System.Collections.Generic.List”。

    class Program
    {
        static void Main(string[] args)

            dynamic result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"});
            string jsonstring = JsonConvert.SerializeObject(result);

            //jsonstring {"data":[{"target_id":9503123,"target_type":"user"}]}
            List<RootObject> datalist = JsonConvert.DeserializeObject<List<RootObject>>(jsonstring);
        }

        public class Datum
