	using System;

	using System.Text;

	namespace ConsoleApplication1
	{
	 class Student
	 {

	 public string Name { get; set; }
	 public string Gender { get; set; }
	 public string Address { get; set; }
	 public int Age { get; set; }

	 public Student() { }

	 /// <summary>
	 /// 注意：可选参数必须放在非可选参数的后面，也就是参数列表的最后面
	 /// </summary>
	 /// <param name="name">非可选参数</param>
	 /// <param name="address">非可选参数</param>
	 /// <param name="gender">可选参数</param>
	 /// <param name="age">可选参数</param>
	 public Student(string name, string address, string gender = "男", int age = 20)
	 {
	 this.Name = name;
	 this.Gender = gender;
	 this.Age = age;
	 this.Address = address;
	 }
	 /*
	 重载操作符，必须用public和static修饰
	 方法可以接收一个以上的参数或两个以上的参数，并且总是返回一个值
	 */

	 public static Student operator +(Student s1, Student s2)
	 {
	 return new Student()
	 {
	 Name = s1.Name + "," + s2.Name,
	 Gender = s1.Gender + "," + s2.Gender,
	 Address = s1.Address + "," + s2.Address,
	 Age = s1.Age + s2.Age
	 };
	 }

	 public static int operator -(Student s1, Student s2)
	 {
	 return s1.Age - s2.Age;
	 }

	 }
	}
