序列化生成JSON数据 宁静以致远

C#版

   using System.Runtime.Serialization.Json;
   using System.IO;

ASPX 页面调用：

C#版：

       Student stu = new Student(1, "小红", "女");
       string str = JsonSerializer(stu);
       Student stuItem = JsonDeserialize<Student>(str);

VB.NET版：

       Dim stu As New Student(1, "张学友", "男")
       Dim str As String = JsonSerializer(stu)
       Dim itemStu As Student = JsonDeserialize(Of Student)(str)
