winform实现计算器-保姆级教程

news 2025/10/28 17:33:30

哈喽大家好，今天想和大家分享一下用winform实现一个简单的计算器。这个案例特别适合刚学winform的小伙伴，锻炼价值特别高。能把前面学的winfrom知识用一遍，而且逻辑也不是特别复杂，对新手比较友好。

目录

一.效果展示

二.创建项目

三.编辑界面

四.编写逻辑代码

4.1处理控件的点击事件

什么是事件？

生成控件初始化代码

在屏幕上展示用户点击的按钮

4.2处理运算逻辑

判断是什么符号

实现四则运算

五.全部代码

1.界面设计代码（Form1.Designer.cs）

2.逻辑代码（Form1.cs）

3.程序入口（Program.cs）

一.效果展示

支持简单的四则运算取余操作

二.创建项目

万丈高楼平地起，我们先从创建项目开始吧。

打开vs2022 -> 点击创建项目 -> 选择winfrom -> 下一步

填写项目名称，选择项目位置

三.编辑界面

在创建好项目之后就可以编辑界面了，主要利用“button”(按钮) 控件

从“工具箱”拖一个“button“控件到窗体上，把该控件的属性“Text”改成1，字体和颜色改成合适的（这个可以随意发挥自己的创意）

然后用上面同样的方法重复操作，直到把界面做成这样子，注意控件上显示上面文字取决于该控件的属性“Text”

界面的样式就做的差不多了，是不是有一点小小的成就感？当然我们还要编写后台逻辑代码

在写逻辑代码之前，我们还要给控件起一个名字。该操作的主要目的是为了让我们自己分清楚，哪个控件对应哪段代码，更加直观。小编之前踩过坑

0-9分别对应button0-button9，加减乘除取余对应add.sub.mul.div.Surplus，点号是spot，等于号是Equal，清零是Clear，结果展示区是Expression

四.编写逻辑代码

4.1处理控件的点击事件

什么是事件？

可以理解成一个行为，通过用户的某种操作，程序会执行预先写好的代码来响应它。

比如说我点击一个按钮"1"，程序能在一个区域显示"1"

计算器程序就正需要一个这样的点击事件，来反馈给用户他点击了什么

接下来我们就来一步一步实现该效果吧

生成控件初始化代码

双击控件就会在From.cs文件中生成对应的代码，让每一个控件都生成一段代码

在屏幕上展示用户点击的按钮

想实现这个效果很简单，只要在点击该控件的时候，把 Expression.Text 改成对应的值即可

例如这样

但是这样做会存在很多冗余的代码，我们可以定义一个全局变量来记录每次点击的值，和一个公共方法来拼接每次点击的值。

public static string GlobalExpresssion = ""; //用来记录每次用户点击按钮的数字
public void AppendNumber(string num) //每次用户点击按钮时调用该控件就可以展示了
{GlobalExpresssion += num;Expression.Text = GlobalExpresssion;
}

清除按钮只需要把Expression.Text改成空值即可

按键部分代码

    #region 按键private void add_Click(object sender, EventArgs e){AppendNumber("+");}private void sub_Click(object sender, EventArgs e){AppendNumber("-");}private void mul_Click(object sender, EventArgs e){AppendNumber("*");}private void div_Click(object sender, EventArgs e){AppendNumber("/");}private void Equal_Click(object sender, EventArgs e){}private void spot_Click(object sender, EventArgs e){AppendNumber(".");}private void Surplus_Click(object sender, EventArgs e){AppendNumber("%");}private void Clear_Click(object sender, EventArgs e) //点清空Expression.Text改成空值{GlobalExpresssion = "";Expression.Text = "";}private void button1_Click(object sender, EventArgs e){AppendNumber("1");}private void button2_Click(object sender, EventArgs e){AppendNumber("2");}private void button3_Click(object sender, EventArgs e){AppendNumber("3");}private void button4_Click(object sender, EventArgs e){AppendNumber("4");}private void button5_Click(object sender, EventArgs e){AppendNumber("5");}private void button6_Click(object sender, EventArgs e){AppendNumber("6");}private void button7_Click(object sender, EventArgs e){AppendNumber("7");}private void button8_Click(object sender, EventArgs e){AppendNumber("8");}private void button9_Click(object sender, EventArgs e){AppendNumber("9");}private void button0_Click(object sender, EventArgs e){AppendNumber("0");}#endregion
}

这样就可以展示用户点击的按钮了

4.2处理运算逻辑

在理想情况下输入两个数希望当点击等于号的时候就计算出结果，所以需要定义一个方法来计算。该方法能够实现基本的运算

        public string Operation(string num) //当点击等于号的时候就调用该方法{//运算逻辑return GlobalExpresssion; //}

判断是什么符号

在Operation方法中需要判断是什么符号并处理对应的运算逻辑，我们之前是把数字和运算符号拼接在全局变量里面，例如10+10这样，可以用Contains来判断该字符串里面有没有对应的运算符号

Contains使用方法

会返回一个bool类型的值，如果存在返回true，不存在则返回false

        public string Operation(string num) //当点击等于号的时候就调用该方法{if(GlobalExpresssion.Contains("+")){}else if(GlobalExpresssion.Contains("-")){}else if (GlobalExpresssion.Contains("*")){}else if (GlobalExpresssion.Contains("/")){}else if (GlobalExpresssion.Contains("%")){}return GlobalExpresssion; //}

这样就可以判断用户想要进行什么样的运算了

实现四则运算

由于我们之前是把数字和运算符号拼接在全局变量里面，所以需要把字符串以运算符号为界限切割开便于计算。

可以使用Split，来进行切割

Split使用方法

string[] result = str.Split(分隔符, 选项);string text = "apple,banana,orange";
string[] fruits = text.Split(','); //以逗号为界限进行切割
// 结果: ["apple", "banana", "orange"]

注意事项：字符串不能直接运算，还要做转换

具体代码

        public string Operation(string num) //当点击等于号的时候就调用该方法{if(GlobalExpresssion.Contains("+")){string[] temps = GlobalExpresssion.Split('+');GlobalExpresssion = (Convert.ToDecimal(temps[0]) + Convert.ToDecimal(temps[1])).ToString();}else if(GlobalExpresssion.Contains("-")){string[] temps = GlobalExpresssion.Split('-');GlobalExpresssion = (Convert.ToDecimal(temps[0]) - Convert.ToDecimal(temps[1])).ToString();}else if (GlobalExpresssion.Contains("*")){string[] temps = GlobalExpresssion.Split('*');GlobalExpresssion = (Convert.ToDecimal(temps[0]) * Convert.ToDecimal(temps[1])).ToString();}else if (GlobalExpresssion.Contains("/")){string[] temps = GlobalExpresssion.Split('/');GlobalExpresssion = (Convert.ToDecimal(temps[0]) / Convert.ToDecimal(temps[1])).ToString();}else if (GlobalExpresssion.Contains("%")){string[] temps = GlobalExpresssion.Split('%');GlobalExpresssion = (Convert.ToDecimal(temps[0]) % Convert.ToDecimal(temps[1])).ToString();}return GlobalExpresssion; //}

这样一个简单的计算器就实现出来了，但是还有一些值得优化的地方
