简单类及成员实例(C#)
题目描述
简单类及成员实例。定义了如下图所示类Student,根据下图和给出代码,补写缺失的代码。
using System;
namespace sample{
class Student {
public string studentid;//学号
public string studentname;//姓名
private string birthplace;//籍贯
private DateTime birthdate;//出生日期
/
//请填写代码,实现类的无参和有参构造函数、
//属性StudentId、StudentName、BirthPlace、BirthDate、Age
/
}
class Program
{
static void Main(string[] args)
{
Student zs = new Student("201753501234", "zs");
zs.BirthDate = DateTime.Parse("1988-12-10");
zs.BirthPlace = "jinan";
string s = "name:{0},no:{1},native:{2},age:{3}";
Console.WriteLine(s,zs.StudentName,zs.StudentId,zs.BirthPlace,zs.Age);
}
}
}
输入
无
输出
输出姓名、学号、籍贯、年龄等信息
样例输入
copy
无
样例输出
name:zs,no:201753501234,native:jinan,age:33
提示
1、年龄Age是只读属性,
2、学号StudentId、姓名StudentName、出生日期BirthDate、籍贯BirthPlace为一般属性;
3、构造函数有无参和有参两种;
public Student(string s1,string s2){studentid = s1;studentname = s2;}public DateTime BirthDate{get { return birthdate; }set { birthdate = value; }}public string BirthPlace{get { return birthplace; }set { birthplace = value; }}public string StudentName{get { return studentname; }}public string StudentId{get { return studentid; }}public string Age{get{DateTime now = new DateTime();now = DateTime.Parse("2021-12-10");TimeSpan ts = now - birthdate;int age = ts.Days / 365;return age.ToString();}}
