编写一个控制台应用程序

编写一个控制台应用程序,要求用户输入6个小写字母,如输入不正确,提示信息并要求重新输入.
小弟 是个新手,帮帮忙能把这个程序写详细点吗?

没有人来吗?

你要的6个小写字母是连续的么?
还是分开的

string s = "";
            for (int i = 0; i < 5; i++)
            {
                s = Console.ReadLine();
                foreach (char c in s)
                {
                    if (c < 'a' || c > 'z')
                        Console.WriteLine("错误");
                    else
                        Console.WriteLine(c.ToString());
                }
            }

............
这个不是和ｗｉｎｆｏｒｍ一样么？？？

using System;
using System.Collections.Generic;
using System.Text;

namespace Console1
{
    class Program
    {
        static void Main(string[] args)
        {
            bool b = false;
            while (b == false)
            {
                Console.Write("请输入6个小写字母:");
                string s = Console.ReadLine();
                if (s.Length != 6)
                {
                    Console.WriteLine("你输入的字母不是6个");
                }
                else
                {
                    b = true;
                    for (int i = 0; i < 6; i++)
                    {
                        char c = s[i];
                        if (c < 'a' || c > 'z')
                        {
                            Console.WriteLine("第{0}个字符{1}不是小写字母,请重新输入.", i + 1, c);
                            b = false;
                            break;
                        }
                    }
                }
            }
            Console.ReadLine();
        }
    }
}
