实现效果：

注意：项目安装json转换工具

两个学生类：

Student.cs代码

    public class Student
    {
        public string stuNO { get; set; }
        public string stuName { get; set; }
        public Student(string stuNO, string stuName)
        {
            this.stuNO = stuNO;
            this.stuName = stuName;
        }
    }

StuList.cs代码

    public class StuList
    {
        public int count { get; set; }
        public List<Student> data;
    }

WebForm.aspx.cs主要代码：

        protected void Button1_Click(object sender, EventArgs e)
        {
            Student stu1 = new Student("2121001","彬菌");
            Student stu2 = new Student("2121002", "彬酱");
            Student stu3 = new Student("2121003", "daobin");
            List<Student> list = new List<Student>();
            list.Add(stu1);
            list.Add(stu2);
            list.Add(stu3);
            StuList stuList = new StuList();
            stuList.count = list.Count;
            stuList.data = list;
            string json = JsonConvert.SerializeObject(stuList);
            ViewState["json"] = json;
            Label1.Text = json;
        }
        protected void Button2_Click(object sender, EventArgs e)
        {
            string json = ViewState["json"].ToString();
            StuList stu = JsonConvert.DeserializeObject<StuList>(json);
            for (int i=0;i<stu.count;i++)
            {
                string info = "学号：" + stu.data[i].stuNO + "姓名：" + stu.data[i].stuName+"<hr />";
                Label2.Text += info;
            }
        }
