我是靠谱客的博主调皮大神，最近开发中收集的这篇文章主要介绍.net 实验三 Windows 应用程序开发（1），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

一、实验目的

1. 掌握窗口控件的使用方法；

2. 掌握 Windows 的编程基础。

二、实验要求

根据要求，编写 C#程序，并将程序代码和运行结果写入实验报告。

三、实验内容

1．编写一个计算器，练习在窗体上添加控件、调整控件的布局，设置或修改控件属性，编写事件处理程序的方法。

(1)新建 windows 应用程序。在窗体 Form 上拖放一个 TextBox 控件、十六个 Button 控

件，整个窗体布局如下图所示。

(2)打开代码窗口，添加如下全局变量：

double a = 0;

double b = 0;

bool c = false;

string d;

双击”1”按钮，添加如下事件处理程序：

private void button1_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox1.Text = "";

c = false;

}

textBox1.Text += "1";

}

(4)双击”2”按钮，添加如下事件处理程序：

private void button2_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox2.Text = "";

c = false;

}

textBox1.Text += "2";

}

(5)双击”3”按钮，添加如下事件处理程序：

private void button3_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox3.Text = "";

c = false;

}

textBox1.Text += "3";

}

(6)双击”4”按钮，添加如下事件处理程序：

private void button4_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox1.Text = "";

c = false;

}

textBox1.Text += "4";

}

(7)双击”5”按钮，添加如下事件处理程序：

private void button5_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox1.Text = "";

c = false;

}

textBox1.Text += "5";

}

(8)双击”6”按钮，添加如下事件处理程序：

private void button6_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox1.Text = "";

c = false;

}

textBox1.Text += "6";

}

(8)双击”7”按钮，添加如下事件处理程序：

private void button7_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox1.Text = "";

c = false;

}

textBox1.Text += "7";

}

(10)双击”8”按钮，添加如下事件处理程序：

private void button8_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox1.Text = "";

c = false;

}

textBox1.Text += "8";

}

(11)双击”9”按钮，添加如下事件处理程序：

private void button9_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox1.Text = "";

c = false;

}

textBox1.Text += "9";

}

(12)双击”0”按钮，添加如下事件处理程序：

private void button12_Click(object sender, EventArgs e)

{

if (c == true)

{

textBox1.Text = "";

c = false;

}

textBox1.Text += "0";

if (d == "/")

{

textBox1.Clear();

MessageBox.Show("除数不能为零", "错误提示", MessageBoxButtons.OK,

MessageBoxIcon.Warning);

}

(13)双击”+”按钮，添加如下事件处理程序：

private void button13_Click(object sender, EventArgs e)

{

c = true;

b = double.Parse(textBox1.Text);

d = "+";

}

(14)双击”-”按钮，添加如下事件处理程序：

private void button16_Click(object sender, EventArgs e)

{

c = true;

b = double.Parse(textBox1.Text);

d = "-";

}

(15)双击”*”按钮，添加如下事件处理程序：

private void button15_Click(object sender, EventArgs e)

{

c = true;

b = double.Parse(textBox1.Text);

d = "*";

}

(16)双击”/”按钮，添加如下事件处理程序：

private void button14_Click(object sender, EventArgs e)

{

c = true;

b = double.Parse(textBox1.Text);

d = "/";

}

(17)双击”=”按钮，添加如下事件处理程序：

private void button17_Click(object sender, EventArgs e)

{

switch (d)

{

case "+": a = b + double.Parse(textBox1.Text); break;

case "-": a = b - double.Parse(textBox1.Text); break;

case "*": a = b * double.Parse(textBox1.Text); break;

case "/": a = b / double.Parse(textBox1.Text); break;

}

textBox1.Text = a + "";

c = true;

}

(18)双击”c”按钮，添加如下事件处理程序：

private void button18_Click(object sender, EventArgs e)

{

textBox1.Text = "";

}

(19)单击启动调试工具，运行计算器。

(20)在计算器中，增加四个功能键：x2，sqrt，log, ln 四个键，分别计算求平方，开方，

log，ln 值，将增加的代码写入实验报告。

2．自己设计并编写一个 Windows 应用程序，要求用到 TextBox、GroupBox、 RadioButton、CheckBox、ComboBox、ListBox 控件、Timer 控件。将程序功能、界面布局和运行结果的截图与事件代码写在实验报告中。
