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

 public class Person
     {
         private string name;

         public string Name
         {
             get { return name; }
             set { name = value; }
         }
         private int age;

         public int Age
         {
             get { return age; }
             set { age = value; }
         }
     }

将List<Person>转化为JSON字符串

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

转化JSON字符串

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