asp.net C# 控制台模拟红绿灯（交通信号灯）
标签：不能 执行 inpu yellow while name OLE returns readline
一、需求分析
通过控制台输入绿灯，黄灯，红灯显示时间，然后倒计时，周而复始。
二、运行效果
1、输入显示时间
2、绿灯，黄灯，红灯，倒计时周而复始
三、实现代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
Console.ForegroundColor = ConsoleColor.Green;
Console.Write("请输入绿灯显示时间：");
int GreenNum = InputNum();
Console.ForegroundColor = ConsoleColor.Yellow;
Console.Write("请输入黄灯显示时间：");
int YellowNum = InputNum();
Console.ForegroundColor = ConsoleColor.Red;
Console.Write("请输入红灯显示时间：");
int RedNum = InputNum();
//循环执行
while (true)
{
//绿灯倒计时
for (int i = GreenNum; i > 0; i--)
{
WriteNum(i, ConsoleColor.Green);
//暂停1秒
Thread.Sleep(1000);
}
//黄灯倒计时
for (int i = YellowNum; i > 0; i--)
{
WriteNum(i, ConsoleColor.Yellow);
//暂停1秒
Thread.Sleep(1000);
}
//红灯倒计时
for (int i = RedNum; i > 0; i--)
{
WriteNum(i, ConsoleColor.Red);
//暂停1秒
Thread.Sleep(1000);
}
}
}
