序列化和反序列化

//序列化 对象转化为可以传输的数据格式

//反序列化 可以传输的数据格式转化为对象

C# 序列化 JsonConvert.SerializeObject()

string conn = ConfigurationManager.ConnectionStrings["connstring"].ConnectionString;
SqlDataAdapter sda = new SqlDataAdapter("select * from Users",conn);
DataSet ds = new DataSet();
sda.Fill(ds);

string res = JsonConvert.SerializeObject(ds);

Response.Write(res);

C# 反序列化 JsonConvert.DeserializeObject()

string jsonStr1 = "{\"UserName\":\"张三\"}";

string jsonStr2 = "{\"List\":[{\"UserName\":\"张三\"},{\"UserID\":\"1\"},{\"UserName\":\"李四\"}]}";

string jsonStr3 = "[{\"UserName\":\"张三\"},{\"UserID\":\"1\"},{\"UserName\":\"李四\"}]";

JObject obj1 = (JObject)JsonConvert.DeserializeObject(jsonStr1); (jsonStr2) (jsonStr3)

obj1["UserName"] obj2["List"][2]["UserName"] obj3[2]["UserName"]

JS 反序列化 JSON.parse() eval()

var json1 = "{\"Name\":\"张三\"}";

var json2 = "{\"List\":[{\"Name\":\"张三\"},{\"ID\":\"1\"},{\"Name\":\"李四\"}]}";

var json3 = "[{\"Name\":\"张三\"},{\"ID\":\"2\"},{\"Name\":\"李四\"}]";

var obj1 = JSON.parse(json1); (json2) (json3)

obj1.Name obj2.List[1]["ID"] obj3[1]["ID"]
