</tr>
<%
foreach (string s in dic.Values)

string[] temp = s.Split(',');

Response.Write("<tr>");
string newA = "<a href=\"usercart.aspx?deleteid=" + temp[0] + "\">删除</a>";
Response.Write(string.Format("<td>{0}<td>{1}<td>{2}<td>{3}<td>{4}</td>", temp[1], temp[2], temp[3], decimal.Parse(temp[2]) * int.Parse(temp[3]), newA));

string deleteid = Request.QueryString["deleteid"];
try
{
int id = int.Parse(deleteid); Dictionary<int, string> dic = Session["cart"] as Dictionary<int, string>;
if (dic.ContainsKey(id))
{
string[] temp = dic[id].Split(',');
int count = int.Parse(temp[3]);
if (count > 1)
{
temp[3] = string.Format("{0}", count - 1);
dic.Remove(id);
dic.Add(id, string.Format("{0},{1},{2},{3}", temp[0], temp[1], temp[2], temp[3]));
Session["cart"] = dic;
Label1.Text = "<script>alert('删除成功!');</script>";
// Response.Write();
}
else
{
dic.Remove(id);
Session["cart"] = dic;

Label1.Text = "<script>alert('删除成功!');</script>";
//Response.Write("<script>alert('删除成功!');</script>");
