c#计算器
简单的C#计算器，但很实用 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace calculator { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Btn_Clear_Click(object sender, EventArgs e) { txt_Result.Text =" "; } private void button0_Click(object sender, EventArgs e) { Button btn=(Button) sender; txt_Result .Text +=btn.Text ; } private void Form1_Load(object sender, EventArgs e) { } private void button1_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text += btn.Text; } private void button2_Click(object sender, EventArgs e) { Button btn=(Button) sender; txt_Result .Text +=btn.Text ; } private void button3_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text += btn.Text; } private void button4_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text += btn.Text; } private void button5_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text += btn.Text; } private void button6_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text += btn.Text; } private void button7_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text += btn.Text; } private void button8_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text += btn.Text; } private void button9_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text += btn.Text; } private void btn_Add_Click(object sender, EventArgs e) { Button btn = (Button)sender; txt_Result.Text = txt_Result.Text + " " + btn.Text + " "; } private void btn_Result_Click(object sender, EventArgs e) { double d_result; string s_txt = txt_Result.Text; int space = s_txt.IndexOf(' '); string s1 = s_txt.Substring(0, space); char operation =System.
