我们这的网被网管限制了不能下载
我只能复制下来
谁有给我发点
我刚学习c#
想弄点程序练练手

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

namespace Compare
{
    class Program
    {
        public int Compare(int max, int min)
        {
            int t;

            if (max<min)
            {
                t = min;
                min = max;
                max = t;
            }
            return max;
        
        }
        public double Compare(double max, double min)
        {
            double t;

            if (max-min<0.0001)
            {
                t = min;
                min = max;         
                max = t;
            }
            return max;

        }
        public string Compare(string max, string min)
        {


            if (max.Length<min.Length)
            {
                return min;

            }

            return max;

        }
        static void Main(string[] args)
        {
            Program max = new Program();

            Console.WriteLine("比较两个整数，请输入两个整数");
            int num1 = int.Parse(Console.ReadLine());
            int num2 = int.Parse(Console.ReadLine());
            Console.WriteLine("大数: {0}", (num1, num2));

            Console.WriteLine("比较两个小数，请输入两个小数");
            double No1 = double.Parse(Console.ReadLine());
            double No2 = double.Parse(Console.ReadLine());
            Console.WriteLine("大数: {0}", (No1, No2));

            Console.WriteLine("比较两个string，请输入两个小数");
            string Sring1 = string.Parse(Console.ReadLine());
            string Sring = string.Parse(Console.ReadLine());
            Console.WriteLine("大数: {0}", (Sring1, String2));

        }

      
    }

}
自己可以学习下。

这个简单啊
看下就知道了
但是你 public string Compare(string max, string min)这个方法
比较的是两个字符串的长短吧

using System;
class Hello
{
    public static void Main()
    {
        Console.WriteLine("hello,world.");
        }
}

简单吧

呵呵，最经典的C#程序~~
，支持你哦~

我也不知道你要多简单的程序，再给你一个吧：

这是个生成验证码的程序，你也可以自己修改
