我不断收到错误消息“输入字符串的格式不正确。”}

Question

I checked in Visual studio with debug both amtBidded and ItemPrice have values of "xx.xx" with quotation marks around them as if they are strings I would like to convert to a decimal or float. The Parse keeps giving me "Input string was not in a correct format." error. I tried the "culture" solutions that were recommended and still get an error.

I am at a loss, any help would be appreciated.

protected void ButtonClicktoBid_Click(object sender, EventArgs e)
    {
        String CurrentBidder = Context.User.Identity.GetUserName();
        String ItemId = ListBoxitemNum.SelectedItem.ToString();
        String ItemPrice = ListBoxCurrentPrice.SelectedItem.ToString();
        String amtBidded = TextBoxAmtBidded.Text.ToString();
        String SecondPlaceBidder = 
        ListBoxCurrentWinningBidder.SelectedItem.ToString();
        String dbMagic;

        if (float.Parse(amtBidded) < float.Parse(ItemPrice))
        {
            Response.Redirect("Default.aspx");
        }

Try like this;

    var currentCulture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
    currentCulture.NumberFormat.CurrencyDecimalSeparator = ".";
    if (float.Parse(amtBidded, NumberStyles.Any, currentCulture) < float.Parse(ItemPrice, NumberStyles.Any, currentCulture))
    {
        Response.Redirect("Default.aspx");
    }
