c# - 如何访问每个循环的 html 属性以进行编码？

Question

我正在尝试访问代码隐藏文件中的这些数据。如果我将这些 html 标签更改为 asp 标签，我将无法从每个循环中检索数据。在这里，我想要每个循环生成的实际销售价格和产品尺寸，以将这些属性保存在数据库中。那么有什么办法可以解决这些问题吗？？

aspx 页面

        <%
                foreach (Com.Idk.Application.ImaraResPOS.Entities.ProductSize psize in psList)
                    { 
                %>
                <div class="col-sm-12  text-center type">

我不确定您为什么要从页面获取数据。既然您是从一些实体对象填充页面，为什么不直接从实体对象获取数据呢？

代码隐藏

foreach (Com.Idk.Application.ImaraResPOS.Entities.ProductSize p in psList)
{ 
    SqlProInsertProductSizeToSale(p.prid, p.sizeID, p.SalesPrice, p.SalesPrice);
}
