C#WPF计算器!一个刚刚入门一个星期Csharp的应届生!

(C#WPF计算器!一个刚刚入门一个星期Csharp的应届生!)

  

先入正题吧!

  

1:创建wpf应用。我用的VS是2013!

  

2:创建wpf文件并且起名字!

  

3:起一条虚线

  

3:打开我们电脑基本的计算器,然后我们模仿他来做计算器吧!

  

4:在工具箱找到lable,把他拖进来。并且起一个名字!设置他的属性。

  

4:再然后在工具箱找到button按钮把他拖进来。并且帮他起名字,还有设置他的属性!

  

5:写完整的界面,按钮直接复制粘贴就可以的!下一步进行后台代码!

  

6:定义三个变量存放数据!

  

7:设置按钮0的点击事件!然后数字键复制粘贴就可以了!

  

8:设置符号键,给他赋值!

  

9:设置C按键清除所有!这个问了很多人才找到的C按键清除lable!

  

10:设置等于号按键促发加减乘除!

  

11:然后一个计算器完成了!下面是全部代码!
