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();
}
}
}

using System.IO;
namespace 计算
{
public partial class Form1 : Form

}
private void button1_Click(object sender, EventArgs e)//写入
{
writes writ = new writes();
string fnm = @"one";
string text1=this.textBox1.Text;
writ.inscribe(fnm, text1);
string fnmm = @"tow";
string text2 = this.textBox2.Text;
writ.inscribe(fnmm, text2);
string fnm1 = @"fuhao";
string text3 = this.comboBox1.Text;
writ.inscribe(fnm1, text3);
textBox1.Clear();
textBox2.Clear();
}
private void button2_Click(object sender, EventArgs e)

clean.cleanup(a, b, c);
}
}
}
form2代码

using System.Windows.Forms;
using System.IO;
namespace 出题
{

}
private void textBox4_KeyDown(object sender, KeyEventArgs e)//后台代码的应用
{
if (e.KeyCode == Keys.Enter)
{

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);
}
}
}
