Question

//编写一个控制台程序，要求用户输入5个大写字母，如果用户输入的信息不满足要求，提示帮助信息并要求重新输入。using System;
using System.Collections.Generic;
using System.Text;namespace HomeWork
{
    class HomeWork_9
    {
        public static void Main()
        {
            int i = 1;
            while(i<=5)
            {
                Console.WriteLine("Enter the {0} word: ",i);
                char a=(char)Console.Read();   //这样读字符对吗？
                if(a>='A'&& a<='Z')
                {
                    Console.WriteLine("The {0} word is {1}",i,a);
                    ++i;
                 }
                 else
                {
                    Console.WriteLine("{0} is not upper word!");
                    Console.WriteLine("Please enter it again.");
                }
            }        }
    }
}//是不是char a=(char)Console.Read();   //这样读字符对吗？
  //的问题呢？

Answer 1

else
                {
                    Console.WriteLine("{0} is not upper word!",a);
                    Console.WriteLine("Please enter it again.");
                    return;
                }
刚才我试了一下楼主的程序,可以执行啊,最好加个return;

Answer 2

static void Main(string[] args)
        {
            int i = 1;
            Console.WriteLine("Enter the 1 word ");
            while (i <= 5)
            {
                //Console.WriteLine("Enter the {0} word ", i);
                char a = (char)Console.Read();
                if (a != 13 && a!=10)
                {
                if (a >= 'A' && a <= 'Z')
                {
                    Console.WriteLine("The {0} word is {1}", i, a);
                    ++i;
                    if (i == 6)
                    {
                        Console.WriteLine("Input right!");
                        Console.ReadKey();
                    }
                    else
                    {
                        Console.WriteLine("Enter the {0} word ", i);
                    }
                }
                else
                {
                    Console.WriteLine("{0} is not upper word!", a);
                    Console.WriteLine("Plase enter it again");
                    continue;
                }
                }
            }
