我有一个项目使用 xslt 文件来显示使用以下代码的记录：

  $(document).ready(function() {
  $(".offers_page").hide();
  $("#OfferPage1").show();
  });
  function OffersPageChange(CurrentPage, NewPage)
  {
   $("#OfferPage" + CurrentPage).hide();
$("#OfferPage" + NewPage).show();
$("$offers_section").focus();
return false;
  }

代码背后的代码是：

void Load_Category(int CategoryId)
    {
        string skinPath = PortalSettings.ActiveTab.SkinPath;

        XDocument XDocOffers = new XDocument(new XElement("Offers"));
        SqlDataProvider provider = new SqlDataProvider();
        SqlConnection SQLConnection = new SqlConnection(provider.ConnectionString);
        SQLConnection.Open();

        SqlConnection SQLConnectionAnswers = new SqlConnection(provider.ConnectionString);
        SQLConnectionAnswers.Open();

        SqlCommand sqlComm = new SqlCommand("OffersGetOffersByCategory", SQLConnection);
        sqlComm.CommandType = CommandType.StoredProcedure;

        sqlComm.Parameters.Add(new SqlParameter("@CategoryId", SqlDbType.Int)).Value = CategoryId;

        SqlDataReader OffersReader = sqlComm.ExecuteReader();

        string OfferId;
        string Partner;
        string Description;
        string ImageSource;
        string Url;
        string UrlText;
        string Email;
        string Phone;
        string LegalInformation;
        string Facebook;
        string Twitter;
        string LegalOnOfferPage;
        string onclick;
        string Emailonclick;
        while (OffersReader.Read())
        {
            OfferId = OffersReader["OfferId"].ToString();
            Partner = OffersReader["Partner"].ToString();
            Description = OffersReader["Description"].ToString();
            ImageSource = OffersReader["ImageSource"].ToString();
            Url = OffersReader["Url"].ToString();
            UrlText = OffersReader["UrlText"].ToString();
            Email = OffersReader["Email"].ToString();
            Phone = OffersReader["Phone"].ToString();
            LegalInformation = OffersReader["LegalInformation"].ToString();
            Facebook = OffersReader["Facebook"].ToString();
            Twitter = OffersReader["Twitter"].ToString();
            LegalOnOfferPage = OffersReader["LegalOnOfferPage"].ToString();
            onclick = "_gaq.push(['_trackEvent', 'Book Now', 'click', '" + Partner + "']);";
            Emailonclick = "_gaq.push(['_trackEvent', 'Email', 'click', '" + Email + "']);";
            XElement NextOffer =
              new XElement("Offer",
                new XElement("OfferId", OfferId),
                new XElement("Partner", Partner),
                new XElement("Description", Description),
                new XElement("ImageSource", ImageSource),
                new XElement("Url", Url),
                new XElement("UrlText", UrlText),
                new XElement("Email", Email),
                new XElement("Phone", Phone),
                new XElement("LegalInformation", LegalInformation),
                new XElement("Facebook", Facebook),
                new XElement("Twitter", Twitter),
                new XElement("LegalOnOfferPage", LegalOnOfferPage),
                new XElement("onclick", onclick),
                new XElement("Emailonclick", Emailonclick)
              );

            XDocOffers.Element("Offers").Add(NextOffer);
        }

        OffersReader.Close();
        SQLConnection.Close();

        string XSLTFile = Server.MapPath(skinPath + "xslt/offers.xslt");
        if (File.Exists(XSLTFile))
        {
            StringWriter XSLTOutput = new StringWriter();
            XmlWriter XMLOutput = XmlWriter.Create(XSLTOutput);

            // Load the style sheet.
            XslCompiledTransform xslt = new XslCompiledTransform();
            xslt.Load(XSLTFile);

            XsltArgumentList ArgumentsQA = new XsltArgumentList();

            if (Settings.ContainsKey("OffersPerPage"))
            {
                ArgumentsQA.AddParam("OffersPerPage", "", Settings["OffersPerPage"].ToString());
            }
            else
            {
                ArgumentsQA.AddParam("OffersPerPage", "", "4");
            }

            ArgumentsQA.AddParam("BasePath", "", "/");

            // Execute the transform and output the results to a writer.
            xslt.Transform(XDocOffers.CreateReader(), ArgumentsQA, XMLOutput);

            //Output.Controls.Add(new LiteralControl(XSLTOutput.ToString().Replace("&amp;", "&")));
            Output.Controls.Add(new LiteralControl(HttpUtility.HtmlDecode(XSLTOutput.ToString())));
        }
        else
        {
            Output.Controls.Add(new LiteralControl("Cannot find XSLT file"));
        }
    }

问题是：

现在以某种不同格式显示交替行的详细信息。目前，每个报价在左侧都有图像，在右侧有描述，对于备用行，现在我想在左侧显示描述，在右侧显示图像，我以前从未使用过 xslt 文件，任何人都可以帮助...或建议我如何实现这一目标。

等待您的有用答案..

我已经解决了这个问题.. 这是解决方案，我们不需要更改 c# 代码中的任何内容（代码隐藏），我们只是更改了 xslt 文件来执行此操作，因为 xslt 文件的内置函数数量要做。

我使用的mod如下：

 <xsl:for-each select=". | following-sibling::Offer[(position()) &lt; $OffersPerPage]" >
<xsl:choose>
         <xsl:when test="position() mod 2 = 1">
             data 1
         </xsl:when>
         <xsl:otherwise>
             data 2
         </xsl:otherwise>
   </xsl:choose>
 </xsl:for-each>

就这样.....
