using System;
namespace Test
{
   class Program
   {
      static void Main(string[] args)
      {
         int guess,number=17;
         do
         {
            Console.WriteLine("你猜测的数:");
            guess=Console.Read();
            if(guess > number)
               Console.WriteLine("太大!");
            if(guess < number)
               Console.WriteLine("太小!");     
         }while(guess!=number);
         Console.WriteLine("恭喜你,你猜中了!");
         Console.ReadLine();
      }
   }
}
语法没有错误，只是得不到应得的结果！为什么？

using System;
namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            int guess;
            int number = 17;
            while(true)
            {
                Console.WriteLine("你猜测的数:");
                guess =int.Parse( Console.ReadLine());
                if (guess > number)
                {
                    Console.WriteLine("太大!");
                    
                }
                else if (guess < number)
                {
                    Console.WriteLine("太小!");
                    
                }
                else if (guess == number)
                {
                    Console.WriteLine("恭喜你猜中了");
                    break;
                }

            }
            
            Console.ReadLine();
        }
    }
}
这样就行了,你得把你输入的东西转为int型  在比较

Console.ReadLine()读进去的是Ascll码

数据读进来的时候没进行类型转换

LS几位已经搞定了

using System;
namespace Test
{
   class Program
   {
      static void Main(string[] args)
      {
         int guess,number=17;
         do
         {
            Console.WriteLine("你猜的数:");
            //guess=int.Parse(Console.ReadLine());
            guess=Convert.ToInt32(Console.ReadLine());
            if(guess>number)
               Console.WriteLine("太大!");
            if(guess<number)
               Console.WriteLine("太小!");
         }while(guess!=number);
         Console.WriteLine("恭喜你，猜对了!");
      }
   }
}
因为Console类的Read（）方法的问题，导致用Read（）方法读入一个数时会引入一些错误的数字！
所以出错，我改为readline方法后就好了，谢谢各位！
