本文实例为大家分享winform版计算器的具体实现方法，供大家参考，具体内容如下

前台页面设计

后台代码实现

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 计算器
{
  public partial class form1 : form
  {
    double c, d;
    string m;
    public form1()
    {
      initializecomponent();
    }




    private void button2_click(object sender, eventargs e)
    {


    }


    private void button8_click(object sender, eventargs e)
    {
      textbox1.text += button8.text;
    }


    private void button1_click(object sender, eventargs e)
    {
      textbox1.text += button1.text;
    }


    private void button2_click_1(object sender, eventargs e)
    {
      textbox1.text += button2.text;


    }


    private void button3_click(object sender, eventargs e)
    {
      textbox1.text += button3.text;
    }

    {
      textbox1.text += button4.text;
    }

    }


    private void button7_click(object sender, eventargs e)
    {
      textbox1.text += button7.text;


    }


    private void button9_click(object sender, eventargs e)
    {
      textbox1.text += button9.text;
    }


    private void button10_click(object sender, eventargs e)
    {
      textbox1.text += button10.text;
    }


    private void button15_click(object sender, eventargs e)
    {
      d= convert.todouble(textbox1.text);
      switch (m)
      { 
        case("+"):
          textbox1.text = convert.tostring(c+d);
          break;
        case ("-"):
          textbox1.text = convert.tostring(c-d);
          break;
        case ("*"):
          textbox1.text = convert.tostring(c * d);
          break;
        case ("/"):
          textbox1.text = convert.tostring(c/d);
          break;


      }
    }


    private void button11_click(object sender, eventargs e)
    {
      c = convert.todouble(textbox1.text);
      textbox1.text = "";
      m = button11.text;
    }


    private void button12_click(object sender, eventargs e)
    {
      c = convert.todouble(textbox1.text);
      textbox1.text = "";
      m = button12.text;
    }


    private void button13_click(object sender, eventargs e)
    {
      c= convert.todouble(textbox1.text);
      textbox1.text = "";
      m = button13.text;
    }


    private void button14_click(object sender, eventargs e)
    {
      c = convert.todouble(textbox1.text);
      textbox1.text = "";
      m = button14.text;
    }


    private void button16_click(object sender, eventargs e)
    {
      textbox1.text = "";
    }
  }
}
