第三次作业 结对编程

软件工程助教老师第三次作业

一 设计思路

由于这次的作业是要我们结对编程的，所以在开始做这次作业的时候，我就找了一个结对编程的小伙伴-----王颜辉。我们决定在新的基础上重新做这次的作业，创建了一个windows窗体应用程序，我们在做关于关于时间和数量上出现了分歧，我坚持认为时间和数量只能有一个，但他坚持要都做，没有办法的我向他妥协了，在选择计算方法上，直接交给用户来选择，做了一个TextBox来接收用户输入是那个四则法则。至于想在什么范围内进行计算，也交给用户自己选择。

二 代码实现

Form1 窗体代码

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 sizeyunsuan

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

public static int count = 0; //定¨义?题琣目?总哩?数簓，?正y确ā?数簓，?四?则ò运?算?的?变?量?

public static int right = 0;

public static int sum;

public static int lefttime;

public static int m1, m2;

public void RandomNum() //定¨义?随?机ú产ú生Θ?随?机ú数簓的?方?法ぁ?

{

try

{

Random ran = new Random();

int n1, n2;

m1 = Convert.ToInt32(textBox5.Text);

m2 = Convert.ToInt32(textBox6.Text);

n1 = ran.Next(m1, m2);

n2 = ran.Next(m1, n1);

textBox2.Text = n1.ToString();

textBox3.Text = n2.ToString();

textBox4.Text = "";

}

catch (Exception ex)

{

MessageBox.Show("请?输?入?数簓值μ范?围§");

}

}

private void Form1_Load(object sender, EventArgs e)

{

}

private void button1_Click(object sender, EventArgs e)

{

int minute;

try

{

minute = int.Parse(this.textBox7.Text);

}

catch (System.Exception ex)

{

this.label8.Text = "输?入?错洙?误ó";

return;

}

lefttime = minute;

this.timer1.Interval = 1000;

this.timer1.Enabled = true;

this.timer1.Start();

RandomNum();

}

public void jiance()

{

}

private void textBox4_KeyDown(object sender, KeyEventArgs e)

{

string m = textBox1.Text;

int n = Convert.ToInt32(textBox8.Text);

int result;

switch (m)

{

case "+":

sum = int.Parse(textBox2.Text) + int.Parse(textBox3.Text);

break;

case "-":

sum = int.Parse(textBox2.Text) - int.Parse(textBox3.Text);

break;

case "×á":

sum = int.Parse(textBox2.Text) * int.Parse(textBox3.Text);

break;

case "÷?":

sum = int.Parse(textBox2.Text) * int.Parse(textBox3.Text);

break;

default:

break;

}

if (e.KeyCode == Keys.Enter)

{

if (int.TryParse(textBox4.Text, out result) == false)

{

MessageBox.Show("请?输?入?数簓字?");

count--;

}

if (textBox4.Text == sum.ToString())

{

right++;

count++;

RandomNum();

}

else

{

count++;

RandomNum();

}

}

if (n == count)

{

MessageBox.Show("题琣目?答鋏完?，?请?重?新?开a始?");

textBox3.Enabled = false;

Form2 frm2 = new Form2();

frm2.ShowDialog();

this.Close();

}

}

private void button2_Click(object sender, EventArgs e)

{

textBox3.Enabled = false;

Form2 frm2 = new Form2();

frm2.ShowDialog();

this.Close();

}

private void textBox1_TextChanged(object sender, EventArgs e)

{

this.label3.Text = this.textBox1.Text;

}

public void timer1_Tick(object sender, EventArgs e)

{

if (lefttime <= 0)

{

timer1.Enabled = false;

MessageBox.Show("答鋏题琣时骸?间?到?！?");

textBox4.Enabled = false;

Form2 frm2 = new Form2();

frm2.ShowDialog();

}

this.label8.Text = "剩骸?余?时骸?间?" + lefttime.ToString() + "秒?";

lefttime--;

}

}

}



Form2 代码

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 sizeyunsuan

{

public partial class Form2 : Form

{

public Form2()

{

InitializeComponent();

}

private void Form2_Load(object sender, EventArgs e)

{

textBox1.Text = Form1.count.ToString();

textBox2.Text = Form1.right.ToString();

textBox3.Text = ((Form1.count - (double)(Form1.right))).ToString();

textBox4.Text = ((Form1.right / (double)(Form1.count)) * 100).ToString() + "%";

}

}

}

四 结对编程总结

这是我第一次和别人做结对编程，感觉自己的想法他接收不了，我的想法他也不理解，在以后的时间里要慢慢去磨合，毕竟这是第一次做。

这对两个人的基础知识要求的很高。希望以后合作的越来越好。
