1.简单封装
1》计算类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; namespace 计算
{
class operater1
{
private int x;
private int y;
private string opers;
private int answer;
public int X
{
set
{
x = value;
}
}
public int Y
{
set
{
y = value;
}
}
public string Opers
{
set
{
opers = value;
}
}
public int Answer
{
get
{
return answer;
}
}
public void operation()
{
switch (opers)
{
case "+":
answer = x + y;
break;
case "-":
if (x > y)
{
answer = x - y;
}
else
{
throw new Exception("被减数不能小于减数！"); }
break;
case "*":
answer = x * y;
break;
case "/":
if (y == 0)
{
throw new Exception("除数不能为零！");
}
else
{
answer = x / y;
}
break; } }
} }
2》写入类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO; namespace 计算
{
class writes
{
public void inscribe(string a, string b)
{ StreamWriter aaa = new StreamWriter(a, true);
aaa.WriteLine(b);
aaa.Close(); }
public void cleanup(string c, string d,string e)
{
StreamWriter ddd = new StreamWriter(c);
ddd.WriteLine(" ");
ddd.Close();
StreamWriter aaa = new StreamWriter(d);
aaa.WriteLine("");
aaa.Close();
StreamWriter fff = new StreamWriter(e);
fff.WriteLine("");
fff.Close();
}
}
}
form1代码

using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO; namespace 计算
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
} private void button1_Click(object sender, EventArgs e)//写入
{

clean.cleanup(a, b, c);
} }
}
form2代码
using System;
using System.Collections.Generic;

using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO; namespace 出题
{
public partial class Form2 : Form

2.策略模式
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; namespace 计算
{
interface operater1
{ int calculate(int a, int b); }
class Add : operater1
{ public int calculate(int a, int b)
{ return a + b; } }
class Sub : operater1
{
public int calculate(int a, int b)
{
return a - b;
}
}
class Mul : operater1
{
public int calculate(int a, int b)
{
return a * b;
}
}
class Div : operater1
{
public int calculate(int a, int b)
{
if (b == 0)
{
throw new Exception("除数不能为零！");
}
else
{
return a / b;
}
}
}
}
实现策略
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; namespace 计算
{
public class Clacuter
{
private operater1 oper1;
public Clacuter(string aSS)
{
switch (aSS)
{
case "+":
oper1 = new Add();
break;
case "-":
oper1 = new Sub();
break;
case "*":
oper1 = new Mul();
break;
case "/":
oper1 = new Div();
break;
} }
public int Calculation(int a,int b)
{
return oper1.calculate(a, b);
}
}
}
2,》写入类
