老陈 ASP.NET封装

第一个页面

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
  
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
      
        StreamWriter n1 = File.AppendText("C:\n1.txt");
        n1.WriteLine(TextBox1.Text);
        n1.Close();
        StreamWriter n2 = File.AppendText("C:\n2.txt");
        n2.WriteLine(TextBox2.Text);
        n2.Close();
        StreamWriter n3 = File.AppendText("C:\n3.txt");
        n3.WriteLine(TextBox3.Text);
        n3.Close();
        ListBox1.Items.Add(TextBox1.Text + TextBox2.Text + TextBox3.Text + "
");
        TextBox1.Text = "";
        TextBox2.Text = "";
        TextBox3.Text = "";
    }
    protected void Button2_Click(object sender, EventArgs e)
    {//跳转页面
        Response.Redirect("Default2.aspx");
    }
}

　　第二个页面

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }//开始
    public static int Count = 0;
    public static int right = 0;
    //总计的个数和正确的个数
     int m = 0;
    protected void Button1_Click(object sender, EventArgs e)
    {
        //出题
        string[] n1 = new string[100];
        n1 = File.ReadAllLines("C:\n1.txt");
        TextBox1.Text = n1[m];
        string[] n2 = new string[100];
        n2 = File.ReadAllLines("C:\n2.txt");
        TextBox2.Text = n2[m];
        string[] n3 = new string[100];
        n3 = File.ReadAllLines("C:\n3.txt");
        TextBox3.Text = n3[m];
        m++;
    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        TextBox4.Enabled = false;
        Response.Write("运算结束！");
        TextBox5.Text = Default2.Count.ToString();//题目总数
        TextBox6.Text = Default2.right.ToString();
        TextBox7.Text = ((Default2.right / (double)(Default2.Count)) * 100).ToString() + "%";//正确率
    }

    protected void Button4_Click(object sender, EventArgs e)
    {
        int a = int.Parse(TextBox1.Text);
        int b = int.Parse(TextBox3.Text);
        Char c = Convert.ToChar(TextBox2.Text);
        Class1 con = new Class1();
        con.chu(a, b, c);
        if (con.answer == int.Parse(TextBox4.Text))
        {
            Response.Write("回答正确！下一题请按开始按钮！");
            right++;
            Count++;
        }
        else
        {
            Response.Write("回答错误！下一题请按开始按钮！");
            Count++;
        }
    }
}

　　.net的封装

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

/// <summary>
///Class1 的摘要说明
/// </summary>
public class Class1
{
    public Class1()
    {

        //
        //TODO: 在此处添加构造函数逻辑
        //
    }
        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;

        }
}
