使用Kentico API

Question

我在Kentico上创建了书店网站，我只使用他们的管理，并使用Kentico API显示我的网站上的数据，但是在获取与特定文档相关的附件文件时我感到非常困难，我使用

获取文档数据没有问题

TreeProvider tree = new TreeProvider(MembershipContext.AuthenticatedUser);
var documents = tree.SelectNodes("CMS.Product");

还需要获取相关的附件文件，如书籍PDF ..我已尝试使用

1. DocumentAttachment
2. AttachmentInfo
3. AttachmentInfoProvider 课程，但我无法得到数据..如果有人帮助我，我将不胜感激。

实际上我正在搜索像GetAttachment（）这样的东西。其中（“AttachmentFile”，“Ënglish文件”）

Answer 1

使用类似

之类的东西解决了

var Attachment = AttachmentInfoProvider.GetAttachments(226, true);

Answer 2

您可以使用以下代码根据列中的值（CMS_Attachment表）过滤返回的附件：

   var attachment = AttachmentInfoProvider.GetAttachments()
       .WhereEquals("AttachmentName", "Englishfile")
       .And()
       .WhereEquals("AttachmentExtension", "jpg")
       .TopN(1)
       .FirstOrDefault();

   if (attachment != null)
   {
         // attachment was found
   }

此代码将获得一个.jpg文件，其中附件名称等于＆＃34; EnglishFile＆＃34;

Answer 3

这是来自Kentico的文档。此示例显示如何添加附件并修改其元数据。您可以忽略该部分。您必须使其通用以适用于所有示例。

Kentico 9 API Links

// Creates a new instance of the Tree provider
TreeProvider tree = new TreeProvider(MembershipContext.AuthenticatedUser);

// Gets a page
TreeNode page = tree.SelectSingleNode(SiteContext.CurrentSiteName, "/Articles", "en-us");

if (page != null)
{
    // Gets an attachment by file name
    AttachmentInfo attachment = DocumentHelper.GetAttachment(page, "file.png", tree);

    // Edits the attachment's metadata (name, title and description)
    attachment.AttachmentName += " - modified";
    attachment.AttachmentTitle = "Attachment title";
    attachment.AttachmentDescription = "Attachment description.";

    // Ensures that the attachment can be updated without supplying its binary data
    attachment.AllowPartialUpdate = true;

    // Saves the modified attachment into the database
    AttachmentInfoProvider.SetAttachmentInfo(attachment);
}
