2、承、接口、与Java几乎同样的语法和编译成中间代码再运行的过程。但是C#与Java有着明显的不同，它借鉴了Delphi的一个特点，与COM（组件对象模型）是直接集成的，而且它是微软公司 .NET windows网络框架的主角。C#是面向对象的编程语言。它使得程序员可以快速地编写各种基于MICROSOFT .NET平台的应用程序，MICROSOFT .NET提供了一系列的工具和服务来最大程度地开发利用计算与通讯领域。C#使得C+程序员可以高效的开发程序，且因可调用由 C/C+ 编写的本机原生函数，因此绝不损失C/C+原有的强大的功能。因为这种继承关系，C#与C/C+具有极大的相似性，熟悉类似语言

3、的开发者可以很快的转向C#。二、 课设目的1. 掌握Visual Studio语言的调试方法。2. 练习利用Visual Studio C#可视化编程实现一些简单功能。三、课设内容及实现的功能制作简单时区时间计算程序设计。可以实现的功能有：时区时差的换算、秒表、计算器（额外）、单位换算（额外）。关键字部分描述：catch：定义一个代码块，在特定类型异常抛出时，执行块内代码。checked：既是操作符又是语句，确保编译器运行时，检查整数类型操作或转换时出现的溢出。finally：定义一个代码块，在程序控制离开try代码快后执行。参见try和catch。fixed：在一个代码块执行时，在固定内存位

4、置为一个变量指派一个指针。namespace：定义一个逻辑组的类型和命名空间。operator：用来声明或多载一个操作符。out：标识一个参数值会受影响的参数，但在传入方法时，该参数无需先初始化。params：声明一个参数数组。如果使用，必须修改指定的最后一个参数，允许可选参数。readonly：标识一个变量的值在初始化后不可修改。ref：标识一个参数值可能会受影响的参数。throw：抛出一个异常。try：异常处理代码块的组成部分之一。try代码块包括可能会，抛出异常的代码。参阅catch和finally关键字。using：当用于命名空间时，using关键字允许访问该命名空间中的类型，而无需指

5、定其全名。也用于定义finalization操作的范围。部分按钮设计流程图 按钮“0”（其余数字按钮类似）四、流程图开始判断textbox1和textbox2,textbox1<24和textbox2<60textbox1和textbox2不是数字在textbox1和textbox2中输入一个时间（textbox<24,texybox2<60）textbox1>=24或textbox2>=60然后点击纽约，时间就会前移13个小时，再按下迪拜，时间前移4个小时 t时间不正确格式不正确 结束 五、程序Form1using System;using System.
