泛型的筛选 Frida

namespace Test

    class Program
    {

        private static List<Student> list1 = new List<Student>();      //声明一个用于放置初始值的集合  注：必须声明List类型而不是IList接口类型
        private static List<Student> list2 = new List<Student>();      //用户存放筛选结果
        static void Main(string[] args)
        {

            //声明实例化student对象
            Student stu1 = new Student("aa", 10);

            Student stu2 = new Student("bb", 13);

            Student stu3 = new Student("cc", 15);

            Student stu4 = new Student("dd", 18);

            //向集合中添加对象
            list1.Add(stu1);

            list1.Add(stu2);
