后台：

public string msg;
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack)
{
if (Session["randomNumber"] == null)

Random random = new Random();
//int randomNumber = random.Next(1, 101);
Session["randomNumber"] = random.Next(1, 101);
Session["count"] = 0;
Session["useTime"] = DateTime.Now;
}
int randomNumber = Convert.ToInt32(Session["randomNumber"]);
//接受前台输入的值
int number = Convert.ToInt32(Request["number"]);
Session["count"] = Convert.ToInt32(Session["count"]) + 1;
if (number > randomNumber)
{
Response.Write("<script>alert('你猜的数字比实际的数大')</script>");
}
else if (number < randomNumber)
{
Response.Write("<script>alert('你猜的数字比实际的数小')</script>");
}
else
{
double useTime = (DateTime.Now - DateTime.Parse(Session["useTime"].ToString())).TotalSeconds;
msg = "猜对了," + "使用次数：" + Convert.ToInt32(Session["count"]) + "用时" + useTime + "秒";
// Response.Write("<script>alert('猜对了')</script>");
}
