本文是当初涉猎C#时写的一个小程序，现在已经没有使用这个语言了。不过想说的是：C#确实我见过的最优雅的语言（也许我见过的语言还少，可能还有比她更优雅的语言吧）。我曾经做过一点Excel和AutoCAD的简单二次开发，使用C#比C++简洁、高效多了。现在就说下这个计算器的设计吧，我还是直接贴代码吧，简洁。

1、首先创建一个大窗体，然后放置各个空间和文本框。创建的界面如下：

2、编写控件触发函数

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace Calculator{    public partial class Form1 : Form    {        string Operation;        public Form1()        {            InitializeComponent();        }        private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)        {        }        private void textBox1_TextChanged(object sender, EventArgs e)        {        }        private void button7_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text+button7.Text;        }        private void button8_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text+button8.Text;        }        private void button9_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text + button9.Text;        }        private void button10_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text + button10.Text;        }        private void button11_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text + button11.Text;        }        private void button12_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text + button12.Text;        }        private void button13_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text + button13.Text;        }        private void button14_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text + button14.Text;        }        private void button15_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text + button15.Text;        }        private void button16_Click(object sender, EventArgs e)        {            textBox1.Text = textBox1.Text + button16.Text;        }        private void button1_Click(object sender, EventArgs e)        {            string str;            str= button1.Text;            textBox1.Text = textBox1.Text + str;            Operation = str;        }        private void button2_Click(object sender, EventArgs e)        {            string str;            str = button2.Text;            textBox1.Text = textBox1.Text + str;            Operation = str;        }        private void button3_Click(object sender, EventArgs e)        {            string str;            str = button3.Text;            textBox1.Text = textBox1.Text + str;            Operation = str;        }        private void button4_Click(object sender, EventArgs e)        {            string str;            str = button4.Text;            textBox1.Text = textBox1.Text + str;            Operation = str;        }        private void button5_Click(object sender, EventArgs e)        {            string str;            str = button5.Text;            string tempStr = textBox1.Text;            textBox1.Text = textBox1.Text + str;            string signal;            signal = Operation;                    string numStr1,numStr2;            string[] StrArray = tempStr.Split(char.Parse(signal));            numStr1 = StrArray[0];            numStr2 = StrArray[1];            double num1, num2,result;            num1 = double.Parse(numStr1);            num2 = double.Parse(numStr2);            switch(signal)            {                case "+":               result=num1+num2;               textBox1.Text = textBox1.Text + result.ToString();                break;                case "-":               result=num1-num2;               textBox1.Text = textBox1.Text + result.ToString();                break;                case "*":               result=num1*num2;               textBox1.Text = textBox1.Text + result.ToString();                break;                case "/":               result=num1/num2;               textBox1.Text = textBox1.Text + result.ToString();                break;            }          }        private void button6_Click(object sender, EventArgs e)        {            textBox1.Text = "";        }        private void label1_Click(object sender, EventArgs e)        {        }        private void label2_Click(object sender, EventArgs e)        {        }    }}
