Question

错误消息不断弹出。此外，当我运行代码时，它似乎根本不起作用。我正在尝试将数据传递到另一个页面。有什么建议吗？这是主页面代码，

public partial class _Default : System.Web.UI.Page
{
static int numBeachBookingInt = 0;
static int numBushBookingInt = 0;
static decimal totRevenue = 0;

protected void Page_Load(object sender, EventArgs e)
{
    string totalRevenue;
    if (Convert.ToString(Session["confirmBooking"]) == "confirm" && Convert.ToString(Session["bachType"]) == "bush")
    {
        totalRevenue = (string)(Session["totalRevenue"]);
        totRevenue += decimal.Parse(totalRevenue);
        totRevenueLabel.Text = String.Format("{0:c}", totRevenue);
        numBushBooking += 1;
        numBushHouseLabel.Text = numBushBooking.ToString();
        Session["confirmBooking"] = "no current booking";
        Session["bachType"] = "none";
    }
    else if (Convert.ToString(Session["confirmBooking"]) == "confirm" && Convert.ToString(Session["bachType"]) == "beach")
    {
        totalRevenue = (string)(Session["totalRevenue"]);
        totRevenue += decimal.Parse(totalRevenue);
        totRevenueLabel.Text = String.Format("{0:c}", totRevenue);
        numBeachBooking += 1;
        numBeachHouseLabel.Text = numBeachBooking.ToString();
        Session["confirmBooking"] = "no current booking";
        Session["bachType"] = "none";
    }
    numBeachHouseLabel.Text = numBeachBooking.ToString();
    numBushHouseLabel.Text = numBushBooking.ToString();

这是第二个。

protected void confirmButton_Click(object sender, EventArgs e)
{
    Session["confirmBooking"] = "confirm";
    Session["totalRevenue"] = totalRateLabel.Text;
    switch (bachTypeRadioButtonList.Text)
    {
        case "Beach":
            Session["bachType"] = "beach";
            break;
        case "Bush":
            Session["bachType"] = "bush";
            break;
        default:
            Session["bachType"] = "none";
            break;
    }
    Response.Redirect("MainBookingForm.aspx");
}

Answer 1

如果没有堆栈跟踪，很难知道你究竟是什么问题。但是，基于谷歌搜索“格式异常未被用户代码取消”，很可能是decimal.Parse(totalRevenue);语句中的一个是问题。由于totalRevenue的字符串值是从totalRateLabel.Text设置的，如果该标签具有您需要首先删除的特殊字符（如美元符号），我不会感到惊讶。

c＃中的用户代码未处理格式异常
