1，计算方法：
namespace ASP.NET
{
public class JiSuan
{
public int S;
public int Result
{
get { return S; } } public int Max(int x, int y, char a)
{
if (a == '+')
{
return S = x + y;
}
else if (a == '-')
{
if (x > y)
{
return S = x - y;
} }
else if (a == '/')
{
if (y == 0 || y < 0)
{
return S = x / y;
} }
else if (a == '*')
{
return S = x * y; }
return S; }
}
2，方法调用：
public partial class 新文件夹1_FZ : System.Web.UI.Page
{
public static int Count = 0;
public static int right = 0;
//JiSuan JS = new JiSuan();
protected void Page_Load(object sender, EventArgs e)
{ } protected void Button1_Click(object sender, EventArgs e)
{
int a = int.Parse(TextBox1.Text.Trim());
int b = int.Parse(TextBox3.Text.Trim());
//int H = int.Parse(TextBox4.Text.Trim());
Char c = Convert.ToChar(TextBox2.Text.Trim());
JiSuan JS = new JiSuan();
JS.Max(a,b,c);
if (JS.Result == int.Parse(TextBox4.Text.Trim()))
{
Count++;
right++;
Label2.Text=("回答正确！");
} else
{
Count++;
Label2.Text = ("回答错误！");
} }
protected void Button2_Click(object sender, EventArgs e)
{
TextBox5.Text = Count.ToString();
TextBox6.Text = right.ToString();
TextBox7.Text = ((right / (double)Count) * 100).ToString() + "%";
}
}
