1.題目要求如下：
C#設計一個簡單的計算器，實現兩個數的加，減，乘，除，求冪等計算，運行效果如下圖所示：
2.這邊需要用到的是VS2019下的C#Windows窗體
3.來吧，展示：
using System;
using System.Windows.Forms;
namespace Calculator
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
MessageBox.Show("歡迎使用小關牌計算器！");
}
private void button1_Click(object sender, EventArgs e)
{
double x = Convert.ToDouble(textBox1.Text);
double y = Convert.ToDouble(textBox2.Text);
double result = x + y;
label4.Text = textBox1.Text + "+" + textBox2.Text + "的值為" + result;
}
private void button3_Click(object sender, EventArgs e)
{
double x = Convert.ToDouble(textBox1.Text);
double y = Convert.ToDouble(textBox2.Text);
double result = x / y;
label4.Text = textBox1.Text + "/" + textBox2.Text + "的值為" + result;
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void label2_Click(object sender, EventArgs e)
{
MessageBox.Show("目前不支持其他運算!");
}
private void label3_Click(object sender, EventArgs e)
{
}
private void textBox3_TextChanged(object sender, EventArgs e)
{
}
private void textBox2_TextChanged(object sender, EventArgs e)
{
}
private void button1_Click_1(object sender, EventArgs e)
{
double x = Convert.ToDouble(textBox1.Text);
double y = Convert.ToDouble(textBox2.Text);
double result = x - y;
label4.Text = textBox1.Text + "-" + textBox2.Text + "的值為" + result;
}
private void button2_Click(object sender, EventArgs e)
{
double x = Convert.ToDouble(textBox1.Text);
double y = Convert.ToDouble(textBox2.Text);
double result = x * y;
label4.Text = textBox1.Text + "*" + textBox2.Text + "的值為" + result;
}
private void button4_Click(object sender, EventArgs e)
{
double x = Convert.ToDouble(textBox1.Text);
double y = Convert.ToDouble(textBox2.Text);
double result = Math.Pow(x, y);
label4.Text = textBox1.Text + "的" + textBox2.Text + "次方為" + result;
}
private void button5_Click(object sender, EventArgs e)
{
//歸零
textBox1.Text = "";
textBox2.Text = "";
label4.Text = "";
}
}
}
此為小關計算器2.0簡明版
4.來看看運行結果：ctrl+f5
這邊自由發揮加上了彈窗提示的效果
這邊演示的為9的9次方結果
希望能幫到大家，問你們要一個贊，你們會給嗎，謝謝大家
