1、已经无语，我添加了正则表达式分割从txt文件读取到的字符串。借我朋友的书《大话设计模式》，感觉作者真乃神人也。第一章就简单明了的介绍了工厂模式，刚好遇到老师这个作业，幸运哈。

2、代码如下

业务逻辑---

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace jisuan
{
    public class Operation
    {
        private double numberA = 0;
        private double numberB = 0;
        public double NumberA
        { 
            get{return numberA;}
            set { numberA = value; }
        }
        public double NumberB
        {
            get { return numberB; }
            set { numberB = value; }
        }
        public virtual double GetResult()
        {
            double result = 0;
            return result;
        }   
    }
    class OperationAdd : Operation
    {
        public override double GetResult()
        {
            double result = 0;
            result = NumberA + NumberB;
            return result;
        }
    }
    class OperationSub : Operation
    {
        public override double GetResult()
        {
            double result = 0;
            result = NumberA - NumberB;
            return result;
        }
    }
    class OperationMul : Operation
    {
        public override double GetResult()
        {
            double result = 0;
            result = NumberA * NumberB;
            return result;
        }
    }
    class OperationDiv : Operation
    {
        public override double GetResult()
        {
            double result = 0;
            if(NumberB==0)
            {
                throw new Exception("除数不能为0");
            }
            result = NumberA / NumberB;
            return result;
        }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;


namespace jisuan
{
    public class OperationFactory
    {
        public static Operation createOperate(string operate)
        {
            Operation oper = null;
            switch (operate)
            {
                case "+":
                    oper = new OperationAdd();
                    break;
                case "-":
                    oper = new OperationSub();
                    break;
                case "*":
                    oper = new OperationMul();
                    break;
                case "/":
                    oper = new OperationDiv();
                    break;
            }
            return oper;
        }
     
    }
}

form4---

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace jisuan
{
    public partial class Form4 : Form
    {
        public Form4()
        {
            InitializeComponent();
        }

        private void Form4_Load(object sender, EventArgs e)
        {
            textBox1.Text = Form2.shijian.ToString();
            textBox2.Text = Form2.right.ToString();
            textBox3.Text = Form2.count.ToString();
            textBox4.Text =((Form2.right/(double)(Form2.count))*100).ToString()+"%";
            textBox5.Text = ((Form2.right / (double)(Form2.shijian)) * 100).ToString() + "%";


        }
    }
}

　　运行效果如下-----
