一、具体代码
Default2.aspx.cs
public partial class Chapter1_Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{ }
int a = ;
private int t;
public static int Count=;
public static int right=;
protected void Button1_Click(object sender, EventArgs e)
{
int a = int.Parse(TextBox1.Text.Trim());
int b = int.Parse(TextBox3.Text.Trim());
Char c = Convert.ToChar(TextBox2.Text.Trim());
Lei con = new Lei();
con.Max(a, b, c);
if (con.Answer == int.Parse(TextBox4.Text.Trim()))
{
Label1.Text=("恭喜你，小朋友！回答正确！");
Label1.ForeColor=Color.Blue;
right++; } else
{ Label1.Text = ("回答错误，继续加油！小朋友");
Label1.ForeColor = Color.Red; } } protected void Button2_Click(object sender, EventArgs e)
{
Count++;
StreamWriter baocun1 = File.AppendText("C:\\baocun1.txt");
baocun1.WriteLine(TextBox1.Text);
baocun1.Close();
StreamWriter baocun2 = File.AppendText("C:\\baocun2.txt");
baocun2.WriteLine(TextBox2.Text);
baocun2.Close();
StreamWriter baocun3 = File.AppendText("C:\\baocun3.txt");
baocun3.WriteLine(TextBox3.Text);
baocun3.Close();
ListBox1.Items.Add(TextBox1.Text + TextBox2.Text + TextBox3.Text + "=");
TextBox1.Text = "";
TextBox2.Text = "";
TextBox3.Text = "";
}
protected void Button3_Click(object sender, EventArgs e)
{
TextBox1.BackColor = Color.Yellow;
TextBox2.BackColor = Color.Yellow;
TextBox3.BackColor = Color.Yellow;
TextBox4.BackColor = Color.Yellow;
TextBox1.Enabled = false;
TextBox2.Enabled = false;
TextBox3.Enabled = false;
string[] m = new string[];
m = File.ReadAllLines("C:\\baocun1.txt");
TextBox1.Text = m[a];
string[] n = new string[];
n = File.ReadAllLines("C:\\baocun2.txt");
TextBox2.Text = n[a];
string[] v = new string[];
v = File.ReadAllLines("C:\\baocun3.txt");
TextBox3.Text = v[a];
a++; } protected void Button4_Click(object sender, EventArgs e)
{
TextBox1.Text = "";
TextBox2.Text = "";
TextBox3.Text = "";
TextBox4.Text = "";
Label1.Text = "";
}
protected void Button5_Click(object sender, EventArgs e)
{
Label6.Text = "总计";
Label7.Text = "正确";
Label8.Text = "正确率";
Label3.Text = Count.ToString();
Label4.Text = right.ToString();
Label5.Text = ((right / (double)(Count)) * ).ToString() + "%";
} }
封装代码：
类代码要写在App_Code里
public class Lei
{ public int Sum; public int Answer
{
get { return Sum; } }
public int Max(int n1,int n2,char yunsuanfu)
{
if (yunsuanfu == '+')
{
return Sum = n1 + n2;
}
else if (yunsuanfu == '-')
{ return Sum = n1 - n2; }
else if (yunsuanfu == '/')
{ return Sum = n1 / n2; }
else if (yunsuanfu == '*')
{
return Sum = n1 * n2; }
return Sum; } }
二、测试
