1序列化

A a=new A();

a.Name="Elain00";

a.Hobby="eat eat";

string jsonStr=JsonConvert.SerializeObject(a);

2反序列化

string jsonstr = "jsonString";
Class model = JsonConvert.DeserializeObject<Class>(jsonstr);

string JsonStr='"{\'Name\':\'Elaine00\',\'Hobby\':\'eat eat\'}";
A a=JsonConvert.DeserializeObject<A>(JsonStr);
