1、C#程序源代码辛苦整理C#程序设计一、实验名称：C#实验二、实验目的：通过上机实际操作将平时课堂所学具体实现，通过该实验来检查自己的学习成功，并且发现平时学习中没有注意到的问题并解决之，从而加深对该门课程的以及C#语言的了解。三、实验步骤：实验一：C#编程环境实验目的：1.熟悉掌握C#开发环境的安装与配置2.熟悉开发环境，编写控制台和窗口两个版本的hello world范例程序实验内容：实验1-1：编写一个控制台程序，并且输出“hello world!”相关主要代码：using System;using System.Collections.Generic;using System.Text;

2、namespace hello_worldclass SY1_2static void Main(string args)Console.WriteLine(Hello World!);抓图结果：实验1-2：编写一个Windows应用程序，并且输出“hello world!”相关主要代码：namespace hello_world2public partial class Form1 : Formpublic Form1InitializeComponent;private void Form1_Load(object sender, EventArgs e)MessageBox.Show(H

3、ello World, Message from C#);抓图结果：实验二：C#编程基础实验目的：1.熟悉掌握C#的各种数据类型，常量、变量的表达形式；2.熟悉掌握C#的运算符和表达式；3.熟悉掌握C#的语言，会使用顺序、选择、循环等语句结构编写程序；4.熟悉掌握C#的数组，学会数组的定义、初始化以及数组的应用。实验内容：实验2-1：有红、黄、黑、白四色球各一个，放置在一个编号为1、2、3、4的四个盒子中，每个盒子放置一只球，它们的顺序不知。甲、乙、丙三人猜测放置顺序如下：甲：黑球在1号盒子，黄球在2号盒子；乙：黑球在2号盒子，白球在3号盒子；丙：红球在2号盒子，白球在4号盒子。结果证明甲、乙

4、、丙三人各猜中了一半，给出四色球放置在盒中的情况。相关的主要代码：using System;using System.Collections.Generic;using System.Text;namespace SY2_1class Programstatic void Main(string args)int a, b, c, d;for(a=1;a<=4;a+)for(b=1;b<=4;b+)for(c=1;c<=4;c+)if(a!=b& b!=c&c!=a)d=10-a-b-c;if(c=1&b=4)&(a=2&d=3) )Console .Write (红球放置在0号，

5、黄球放置在1号，,a,b);Console .WriteLine (黑球放置在0号，白球放置在1号,c,d);Console .Read ;抓图结果：实验2-2：采用筛选法求2-64之间的质数。相关主要代码：using System;public class TestNumSortpublic static void Mainint sieve, w;int i, j, p, k;bool flg = true;sieve = _0x0;p = 3;for (i = 0; i < 32; i+)w = 0x1 << i; w <<= p; j = p;while (j +
