Net对象转化为Josn格式的字符串
1.序列化数组格式为json标准的字符串
string[] strs = { "rupeng", "baidu", "qq" };
JavaScriptSerializer jss = new JavaScriptSerializer();
string json = jss.Serialize(strs);
//context.Response.Write(json);
2.序列化一个Person的对象为Json标准的字符串
//实力化一个person对象
Person peo = new Person();
peo.Id = 123;
peo.Name = "雷军";
peo.Age = 20;
string json1 = jss.Serialize(peo);//序列化
//context.Response.Write(json1);//此处就会生成json格式的字符串 {"Name":"雷军","Age":20,"Id":123}
3.序列化List集合成为Json格式的字符串
Person peo1 = new Person();
peo1.Id = 1;
peo1.Name = "将军";
peo1.Age = 20;
Person peo2 = new Person();
peo2.Id = 1;
peo2.Name = "司令";
peo2.Age = 26;
List<Person> list = new List<Person>();
list.Add(peo1);
list.Add(peo2);
JavaScriptSerializer jj = new JavaScriptSerializer();
string jsonn = jj.Serialize(list);
// context.Response.Write(jsonn);
4.序列化对象数组
Person[] pe = new Person[] { peo1, peo2 };
JavaScriptSerializer js = new JavaScriptSerializer();
string jssss = js.Serialize(pe);
context.Response.Write(jssss);
5.序列化匿名类对象
//序列化匿名类对象为Json格式
var p3=new {Id=8,Name="如鹏",Height=189};
JavaScriptSerializer js2 = new JavaScriptSerializer();
string jsj = js2.Serialize(p3);
context.Response.Write(jsj); //结果：{"Id":8,"Name":"如鹏","Height":189}
