如何将C#对象转化为JSON字符串

System.Web.Extensions.dll中类JavaScriptSerializer可以帮助我们把C#对象转化为JSON字符串。

有一个Person类

 1 public class Person
 2     {
 3         private string name;
 4
 5         public string Name
 6         {
 7             get { return name; }
 8             set { name = value; }
 9         }
10         private int age;
11
12         public int Age
13         {
14             get { return age; }
15             set { age = value; }
16         }
17     }

将List<Person>转化为JSON字符串

1             List<Person> persons = new List<Person>();
2             persons.Add(new Person() {Name="zhangsan" ,Age=26});
3             persons.Add(new Person() { Name = "lisi", Age = 26 });
4             JavaScriptSerializer jss = new JavaScriptSerializer();
5             string personsjson = jss.Serialize(persons);

转化JSON字符串

personsjson = "[{"Name":"zhangsan","Age":26},{"Name":"lisi","Age":26}]"
