尝试完成代码以将年龄与18进行比较并给出解决方案 [英] Trying to finish code to compare age to 18 and give solution

问题描述

我目前正在尝试制作一个简单的程序，让用户在控制台窗口中为我提供他的出生年份。然后我将从当前年份中减去它并将其与18进行比较。我为date.time.year做了一个int - userdateofbirth并且我试图将它与18进行比较以给出if then语句。如果超过18岁他们将能够继续，如果没有，那么他们会被拒绝。到目前为止我的代码是

 使用系统; 
 使用 System.Collections.Generic; 
 使用 System.Linq; 
 使用 System.Text; 
 使用 System.Threading.Tasks; 
 
 命名空间 ConsoleApplication2 
 {
  class  Program 
 {
 静态  void  Main（ string  [] args）
 {
  string 谢谢; 
 Console.WriteLine（ 感谢您选择与我们一起购物）; 
 Console.ReadLine（）; 
 
  string 诞生; 
  int  Birthint; 
 Console.WriteLine（ 要完成购买，请输入您的出生日期。 ）; 
 Birth = Console.ReadLine（）; 
 Birthint = Convert.ToInt32（出生）; 
 Console.ReadLine（）; 
 
 Console.WriteLine（ 今年是 + DateTime.Now。年）; 
 Console.WriteLine（ 你是 +（DateTime.Now.Year  -  Birthint） +  岁。）; 
 Console.ReadLine（）; 
 
  int  Oldint =（DateTime.Now.Year  -  Birthint）; 
 Oldint = Convert.ToInt32（Oldint）; 
 
 
 
 
 
 
 如果（Oldint >  =  18 ）
 
 
  //  你已超过18  
 
 如果（Oldint < span class =code-keyword><  =  18 ）
 
  //  你未满18岁 
 
 
 
 Console.ReadLine（）; 
 
 
 
 
 
 
 
 
 
 
 
 
 
} 
} 
} 

任何建议从哪里开始？

解决方案

要计算年龄，请使用类似的东西：

 DateTime date1 =  new  DateTime（ 2001 ， 1  ， 15 ）; 
 DateTime date2 = DateTime.Today; 
 
  int  age = date2.Year  -  date1.Year; 
 
 Console.WriteLine（ 你是{0} 18岁 ，年龄< 18？ 在：  over）;

I'm currently trying to make a simple program that will ask a user in a console window to give me his year of birth. I will then subtract it from the current year and compare it to 18. I made an int for date.time.year - userdateofbirth and am trying to compare that to 18 to give an if then statement . If over 18 they will be able to continue, if not then they get rejected. My code so far is

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            string Thanks;
            Console.WriteLine("Thank you for choosing to shop with us");
            Console.ReadLine();

            string Birth;
            int Birthint;
            Console.WriteLine("To complete your purchase, please enter your date of birth.");
            Birth = Console.ReadLine();
            Birthint = Convert.ToInt32(Birth);
            Console.ReadLine();

            Console.WriteLine("This year is " + DateTime.Now.Year);
            Console.WriteLine("You are " + (DateTime.Now.Year - Birthint) + " years old.");
            Console.ReadLine();

            int Oldint = (DateTime.Now.Year - Birthint);
            Oldint = Convert.ToInt32(Oldint);






            if (Oldint >= 18)


                //you are over 18

            if (Oldint <= 18)

                //you are under 18



                Console.ReadLine();













        }
    }
}

any suggestions on where to go from here?

解决方案

To calculate age, use something similar to:

DateTime date1 = new DateTime(2001,1,15);
DateTime date2 = DateTime.Today;

int age = date2.Year - date1.Year;

Console.WriteLine("You are {0} 18 years old", age<18 ? "under" : "over");
