在这里，您将得到它的价值。这是 Asp.Net 控件中用于显示图书信息的代码。您可能可以轻松地根据您的目的调整它。或者至少给你一个起点。如果您确实需要，我很乐意将控件捆绑起来并发送给您。

if (!(string.IsNullOrEmpty(ISBN) && string.IsNullOrEmpty(ASIN)))
{
    AWSECommerceService service = new AWSECommerceService();
    ItemLookup lookup = new ItemLookup();
    ItemLookupRequest request = new ItemLookupRequest();

    lookup.AssociateTag = ConfigurationManager.AppSettings["AssociatesTag"];
    lookup.AWSAccessKeyId = ConfigurationManager.AppSettings["AWSAccessKey"];
    if (string.IsNullOrEmpty(ASIN))
    {
        request.IdType = ItemLookupRequestIdType.ISBN;
        request.ItemId = new string[] { ISBN.Replace("-", "") };
    }
    else
    {
        request.IdType = ItemLookupRequestIdType.ASIN;
        request.ItemId = new string[] { ASIN };
    }
    request.ResponseGroup = ConfigurationManager.AppSettings["AWSResponseGroups"].Split(new char[] { ' ', ',', ';' }, StringSplitOptions.RemoveEmptyEntries);

    lookup.Request = new ItemLookupRequest[] { request };
    ItemLookupResponse response = service.ItemLookup(lookup);

    if (response.Items.Length > 0 && response.Items[0].Item.Length > 0)
    {
        Item item = response.Items[0].Item[0];
        if (item.MediumImage == null)
        {
            bookImageHyperlink.Visible = false;
        }
        else
        {
            bookImageHyperlink.ImageUrl = item.MediumImage.URL;
        }
        bookImageHyperlink.NavigateUrl = item.DetailPageURL;
        bookTitleHyperlink.Text = item.ItemAttributes.Title;
        bookTitleHyperlink.NavigateUrl = item.DetailPageURL;
        if (item.OfferSummary.LowestNewPrice == null)
        {
            if (item.OfferSummary.LowestUsedPrice == null)
            {
                priceHyperlink.Visible = false;
            }
            else
            {
                priceHyperlink.Text = string.Format("Buy used {0}", item.OfferSummary.LowestUsedPrice.FormattedPrice);
                priceHyperlink.NavigateUrl = item.DetailPageURL;
            }
        }
        else
        {
            priceHyperlink.Text = string.Format("Buy new {0}", item.OfferSummary.LowestNewPrice.FormattedPrice);
            priceHyperlink.NavigateUrl = item.DetailPageURL;
        }
        if (item.ItemAttributes.Author != null)
        {
            authorLabel.Text = string.Format("By {0}", string.Join(", ", item.ItemAttributes.Author));
        }
        else
        {
            authorLabel.Text = string.Format("By {0}", string.Join(", ", item.ItemAttributes.Creator.Select(c => c.Value).ToArray()));
        }
        ItemLink link = item.ItemLinks.Where(i => i.Description.Contains("Wishlist")).FirstOrDefault();
        if (link == null)
        {
            wishListHyperlink.Visible = false;
        }
        else
        {
            wishListHyperlink.NavigateUrl = link.URL;
        }
    }
}
