窗体四则运算。
我用的是窗体来做的 老师教过 比较简单的方法。
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 szys.c
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private static int
Count = 0,
right = 0;
private void ys()
{
Random rn = new Random();
int i, j;
i = rn.Next(11);
j = rn.Next(1, 11);
textBox1.Text = i.ToString();
textBox2.Text = j.ToString();
textBox3.Text = "";
}
private void button1_Click_1(object sender, EventArgs e)
{
label1.Text = "+";
label1.Visible = true;
}
private void button2_Click_1(object sender, EventArgs e)
{
label1.Text = "-";
label1.Visible = true;
}
private void button3_Click(object sender, EventArgs e)
{
label1.Text = "*";
label1.Visible = true;
}
private void button4_Click(object sender, EventArgs e)
{
label1.Text = "/";
label1.Visible = true;
}
private void button5_Click_1(object sender, EventArgs e)
{
ys();
}
private void button6_Click_1(object sender, EventArgs e)
{
textBox3.Enabled = false;
MessageBox.Show("运算结束！");
}
private void textBox3_KeyDown_1(object sender, KeyEventArgs e)
{
if (label1.Text == "+")
{
int sum;
sum = int.Parse(textBox1.Text) + int.Parse(textBox2.Text);
if (e.KeyCode == Keys.Enter)
{
if (textBox3.Text == sum.ToString())
{ right++;
Count++;
}
else
Count++;
textBox4.Text = Count.ToString();
textBox4.Enabled = false;
textBox5.Text = right.ToString();
textBox5.Enabled = false;
ys();
}
}
else if (label1.Text=="-")
{ int cha;
cha = int.Parse(textBox1.Text) - int.Parse(textBox2.Text);
if (e.KeyCode == Keys.Enter)
{
if (textBox3.Text == cha.ToString())
{
right++;
Count++;
}
else
Count++;
textBox4.Text = Count.ToString();
textBox4.Enabled = false;
textBox5.Text = right.ToString();
textBox5.Enabled = false;
ys();
}
}
else if (label1.Text=="*")
{
int qj;
qj = int.Parse(textBox1.Text) * int.Parse(textBox2.Text);
if (e.KeyCode == Keys.Enter)
{
if (textBox3.Text == qj.ToString())
{
right++;
Count++;
}
else
Count++;
textBox4.Text = Count.ToString();
textBox4.Enabled = false;
textBox5.Text = right.ToString();
textBox5.Enabled = false;
ys();
}
}
if (label1.Text=="/")
{
double chu;
chu = int.Parse(textBox1.Text) /int.Parse(textBox2.Text);
if (e.KeyCode == Keys.Enter)
{
if (double.Parse (textBox3.Text)==chu )
{
right++;
Count++;
}
else
Count++;
textBox4.Text = Count.ToString();
textBox4.Enabled = false;
textBox5.Text = right.ToString();
textBox5.Enabled = false;
}
}
}
}
}
思路就是用窗体构建出模型，然后编写代码，用时1小时。
