Answer 1

namespace Test
{
    class Program
    {
        /*
         * *1、封装一个被称为日期TDate类。用这个类存储年、月、日。 
         * 1）Show（）成员函数显示某日期对象的信息，格式为日、月、年。 
         * 2）可运行在日期上加一天的操作成员函数add（）（不考虑年底月底情况）。 
         * 3）设置日期。
         */
        public static void Main(string[] args)
        {
            Student[] ss = new Student[5]
           {
               new Student("小唐","1001",1000),
               new Student("小孙","1002",500),
               new Student("小猪","1003",400),
               new Student("小沙","1004",300),
               new Student("小白","1005",200)
           };
            foreach (Student s in ss)
            {
                s.Show();
            }
        }
        public class Student
        {
            private string id;
            private string name;
            private int age;
            public Student()
        {
            Set("", "", 0);
        }
            public Student(string name, string id, int age)
            {
                Set(id, name, age);
            }
            private void Set(string id, string name, int age)
            {
                this.id = id;
                this.name = name;
                this.age = age;
            }
               
            public void Show()
            {
                Console.WriteLine("我叫{0}\n我的学号是{1}\n我{2}岁了\n",name,id,age);
            }
        }
    }
}

Answer 2

public class Student
{
public int SID; //学号
public string Name; //姓名

public int Age; // 年龄

public Student(int id, string name, int age) //构造方法

{
SID = id;

Name = name;

Age = age;

}

public void Example() //数组赋值示例

{
Student[] students = new Student[2];
students[0] = new Student(1, "张三", 10);

students[1] = new Student(2, "李四", 11);

}
}

追问

谢谢，但是学号，姓名，年龄要用private的私有属性。可不可以告诉我怎么写...怎么打印出来

你需要连接数据库吗？
