我正在嘗試將存儲在會話變量中的項目存入中繼器供用戶查看。但是，我不完全確定如何做到這一點（我是新會話變量）。基本上，當用戶輸入一次頁面上的項目數量時，它們將被帶到「訂單彙總」頁面，該頁面將顯示他們計劃購買的內容。我已經成功地設置了一個會話變量來包含用戶選擇的每個產品的sku和數量，但我不知道如何獲取信息。在中繼器內的會話變量內顯示項目？
我已將信息存儲在會話變量中，如[sku]，[quantity]; [sku]，[quantity]; [sku]，[quantity]等等。我想我必須做一個拆分或基於逗號和分號的東西，但我不知道如何用會話變量來做到這一點。
包含要存儲在會話變量中的產品列表網頁代碼：

這裏是，是爲了保持訂單彙總中繼設計師代碼：
<asp:Repeater ID="orderRepeater" runat="server" >
<headertemplate>
<tr>
<th>SKU</th>
<th>Quantity</th>
</tr>
</headertemplate>
<itemtemplate>
<tr>
<td><%#Eval("sku") %></td>
<td><%#Eval("qty") %></td>
</tr>
</itemtemplate>
</asp:Repeater>
這裏是後面的代碼：
private void Page_Load(object sender, EventArgs e)
{
Item CurrentItem = Sitecore.Context.Item;
Item HomeItem = ScHelper.FindAncestor(CurrentItem, "gojoMarket");
if (Session["orderComplete"] != "")
{
if (HomeItem != null)
{
Item ProductGroup = HomeItem.Axes.SelectSingleItem(@"child::*[@@templatename='gojoMarketOfficeBuildigProductMap']/*[@@templatename='gojoOrderReview']");
if (ProductGroup != null)
{
//this is where I am confused on how to proceed
}
}
}
}
一切正在工作，我對會話變量做了一個Response.Write測試，以確保它具有正確的信息，並且確實如此。
在此先感謝！
我喜歡這個想法。儘管最初我將信息存儲在一個ArrayList中，然後通過該信息進行排序以填充會話變量。我更新了我的帖子以顯示產品列表頁面的代碼.... –
'if（Session [「orderComplete」]！= null && Session [「orderComplete」]！=「」）''可以修剪爲' if（！string.IsNullOrWhiteSpace（Session [「orderComplete」]））' –
