窗体及控件程序设计

1、河南城建学院计算机科学与工程系c#语言windows程序设计实验报告实验名称：窗体及控件程序设计成绩专业班级：信息管理与信息系统姓名：赵文普学号：083411151实验日期：2013 年10 月 日软件环境：开发工具：硬件环境：硬盘：内存：一、实验目的(1) 掌握c#窗体创建及其常用控件的选用和编程。(2) 进一步提高编程能力，掌握对c#方法的调用及其参数类型的设置。(3) 练习简单应用程序的规划设计及其程序开发的方法。二、实验内容(1)设计一个简易计算器，包括0,1,2,3,4,5,6,7,8,9,+-*/二十六个按钮通过一个文木框,显示输出的结果。三、实验数据using system;us
