获取ipn option_name_1_1 C＃的变量

Question

我有一个具有3个选项下拉菜单的贝宝购物车按钮。 第一个是样式-T恤，汗水，兜帽-这个价格各有关系，然后还有两个其他的尺寸和颜色。 这是一个C＃ASP.NET应用程序。 如果我查看侦听器获得的全部响应（所有变量），则样式为“ option_name1_1”，并且它将按应返回“样式”。 但是在列表'option_selection_1_1'=“ Sweat”中，这是我选择的内容，但是当我调用该值时它什么也没有显示。 这是将响应传递给用户的代码。

    if (strResponse.StartsWith("SUCCESS"))
            {

                PDTHolder pdt = PDTHolder.Parse(strResponse);

                Label1.Text =
                    string.Format("" + pdt.PayerFirstName + " " + pdt.PayerLastName   + " for your payment of " + pdt.GrossTotal + " " + pdt.Currency + " option:"+pdt.OptionName+" : "+pdt.OptionOne+":"+pdt.OptionName2+ " :" + pdt.OptionTwo+"!",
                    pdt.PayerFirstName, pdt.PayerLastName,
                    pdt.PayerEmail, pdt.GrossTotal, pdt.Currency);

这是侦听器用来解析响应的类。

这是我的IPN的摘录：希望对您有所帮助：

for (var iloop = 1; iloop <= Convert.ToInt32(inTransaction["num_cart_items"]); iloop++)
                {

                    var currentitem = new PurchasedItem(ID, inTransaction["item_name" + iloop],
