第三次作业

 这是我和寝室的哥们关高磊合作结对一起编程的

 

  Form1的代码如下：

uesing 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 WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public static int count;
        public static int t=0;
        public static int shijian;
        public static int z;
        public static int right;
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            int m = int.Parse(textBox5.Text);
            int n = int.Parse(textBox6.Text);
            if(m>n)
            {
                MessageBox.Show("亲，选择范围，需要第一个数字大于第二个哦");
                textBox5.Text = "";
                textBox6.Text = "";
                //如果用户用户选择的取数范围不符合的话，则清空
            }
            textBox4.Text = t.ToString();
            timer1.Enabled = true;
            timer1.Interval = 1000;
            timer1.Start();
            Randomsj();

        }
        private void Randomsj()
        {
           
            int m = int.Parse(textBox5.Text);
            int n = int.Parse(textBox6.Text);
            Random sj = new Random();
            int x = sj.Next(m,n);
            int y = sj.Next(m,x);
            //这里让随机数第二个永远小于等于第一个，且获取用户输入的范围
            textBox1.Text = x.ToString();
            textBox2.Text = y.ToString();

            textBox7.Text = comboBox1.Text.ToString();
            textBox3.Text = "";
            count++;
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            t = t + 1;
            textBox4.Text = t.ToString();
        }

        private void textBox3_KeyDown(object sender, KeyEventArgs e)
        {
            int x = int.Parse(textBox1.Text);
            int y = int.Parse(textBox2.Text);
            string cb = comboBox1.Text;
            switch (cb)
            {
                case "+":
                    z = x + y;
                    break;
                case "-":
                    z = x - y;
                    break;
                case "*":
                    z = x * y;
                    break;
                case "/":
                    z = x / y;
                    break;
            }
            if(e.KeyCode==Keys.Enter)
            {
                if(textBox3.Text==z.ToString())
                right++;
                Randomsj();
               

      

            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            timer1.Enabled = false;
            textBox3.Enabled = false;
            shijian = int.Parse(textBox4.Text);
            //前面shi获取最初的时间，当点击停止时，jian获取现在的时间，shijian则就是form2的所用时间
            Form2 ff = new Form2();
            ff.ShowDialog();
            Form1 f = new Form1();
            f.Close();

       

    }

}

Form2的代码如下：

 

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 WindowsFormsApplication1
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.Close();
        }

        private void Form2_Load(object sender, EventArgs e)
        {
            textBox1.Text = Form1.shijian.ToString();
            textBox2.Text = Form1.count.ToString();
            textBox3.Text = Form1.right.ToString();
            textBox4.Text = ((Form1.right / (double)(Form1.count)) * 100).ToString() + "%";
        }
    }
}
