C# Winform 仿Win10-计算器

源码：https://github.com/Cheng-xiaozhen/Simple-Win-10-Calculator

效果图

当然与Win10的还是有很多差距的左图是Win10的

同时，win10的图标是白色的，相应的找了个黑色的图标

简单计算

计算 12*3 = 36

查看计算记录

出现计算错误的时候
计算 12/0

除了清除C键，其他的按钮都锁住

点击菜单，切换模式

这个就不做了。。。

做之前，想到了以前用JAVA做的那个计算器，本打算仍用JAVA做的时候的那个思路，点相应的按钮，在文本框，输入相应的文本，在点击 = 的时候，讲整个表达式，转换成后缀表达式，再求值。
后来，觉得有点不妥，虽然计算结果正确，但既然要仿win10的计算器，那也就仿win10计算器的计算方法，所以这次增加一个label，在输入第二个数的时候，将第一个数存到 label中，然后再计算。

昨天实验课的时候，将布局基本搭建完成。今天晚上把功能基本也完成了，但是，没经过大量的测试，可能还会有一些小问题。发现问题，请留言。
