C编的计算器Word版

1、网络程序设计作业（三）学院：教育科学与技术学院班级：10级教计三班姓名：张敏学号：100401041334日期：2011年11月7日1 / 11在线计算器的设计与实现一、界面设计1.界面截图如下：2设计步骤：（1）打开Visual Web Developer 2008软件，把“default.aspx”重命名为“zaixianjisuanji.aspx”。（2）打开该项的设计界面，在div块标签中输入“在线计算器”。（3）在工具箱拖入一个文本框TextBox，在属性栏中设置其属性值。（4）拖入一个Table控件,设置其行列分别为5,4。并设置其大小边框值等。（5）在每个格子里拖入一个butto

2、n按钮控件，在第五行合并前两个单元格。并如上图设置其Text的值。二、程序设计using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class _Default : System.Web.UI.Pageprivate Calulate obj1; public void Page_Load(object sender, EventArgs e) if (!
