【问题描述】:
我有这个基于 C# 面向对象编程的计数器程序和 计数器有一个增量方法,它从 0..1...2.. 增加到 30。
for 循环工作得非常好,但后来我决定添加一个包含两个方法的类,这些方法可以以奇数步数或偶数步数进行计数,这些方法也可以正常工作。唯一的问题是,在更改主类之后,它在 30 之前不再循环工作,所以我必须单独输入每个步骤。
这是我的主要代码(我很确定问题是由于Console.ReadLine 和一般输入,但我不知道究竟是什么问题)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Counter
{
class Program
{
static void Main(string[] args)
{
char confirm;
int input;
do
{
//int inNum;
Console.Clear();
ModusCounter b = new ModusCounter(0, 30);
for (; ; )
{
b.Display(19, 7);
Console.Write("do you want (1)odd // (2) even // (0)standard ? ");
input = Convert.ToInt32(Console.ReadLine());
if (input == 1)
{
b.OddCount();
}
else if (input == 2)
{
b.EvenCount();
}
else
b.Increment();
System.Threading.Thread.Sleep(300);
if (Console.KeyAvailable) break;
}
//b.Increment();
b.Display(19, 7);
Console.WriteLine();
Console.WriteLine();
Console.WriteLine("do you want to restart? (J // N) ");
confirm = Convert.ToChar(Console.ReadLine());
}
while (confirm == 'J');
Console.ReadLine();
}
}
}
模式计数器:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Counter
{
public class ModusCounter:CCounter
{
private int wholenum;
public int Wholenum
{
get => wholenum;
set
{
wholenum = value;
}
}
public ModusCounter(int start, int limit) : base(start, limit)
{ }
public void EvenCount() //2
{
Wholenum = 2;
Level += Wholenum;
if (Level % 2 == 0)
{
Level += Wholenum - 2;
}
else
{
Level += Wholenum -1;
}
if (Level > Limit)
Level = Start;
}
public void OddCount() //1
{
Wholenum = 1;
Level += Wholenum;
if (Level % 2 == 0)
{
Level += Wholenum;
}
else
{
Level += Wholenum + 1;
}
if (Level > Limit)
Level = Start;
}
}
}
基类:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Counter
{
public class CCounter
{
private int start;
private int limit;
private int level;
public int Start
{
get => start;
protected set
{
start = value;
}
}
public int Limit
{
get => limit;
protected set
{
limit = value;
}
}
public int Level
{
get => level;
protected set
{
if (value < Start)
level = Start;
else if (value > Limit)
Level = Limit;
else
level = value;
}
}
public CCounter(int start_, int limit_)
{
Start = start_;
Limit = limit_;
Level = Start;
}
public void Increment()
{
int level = Level + 1;
if (level > Limit9
Level = Start;
else
Level = level;
}
public void Display(int x_, int y_)
{
Console.SetCursorPosition(x_, y_);
Console.Write(Level.ToString("00"));
}
}
}
