封装如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace 老程
{
class Class1
{
public int sum;
public int answer
{
get
{
return sum;
}
}
public int chu(int n1, int n2, char fuhao)
{
if (fuhao == ‘+‘)
{
return sum = n1 + n2;
}
else if (fuhao == ‘-‘)
{
return sum = n1 - n2;
}
else if (fuhao == ‘*‘)
{
return sum= n1 * n2;
}
return sum;
}
}
}
总结：在做这次的封装，遇到了很多困难，从当初的不知道封装是什么，怎么去做，到今天才把这个做好。我知道我的代码不是很好，这是老师布置作业后我开始看我以前C#的书和请教已经完成的同学，然后无数次的测试，修改我的代码，到现在做成这样，不过我的实现功能不是特别全，不会保存，不过我的下一步会完善的，我会继续努力让自己跟上去的。
