如何将文档从 Sharepoint 文档库返回给用户？

我正在从 Sharepoint 库检索文档列表。假设我的任务是向用户检索该列表中的第一个文档，以便他可以打开 docx 文件。我该如何去做呢？

更复杂的是共享点服务器位于另一个域。我正在开发的 Web 项目将向客户展示文档，但不会公开对共享点服务器的直接访问。

    ClientContext clientContext = new ClientContext(URL);
    List list = clientContext.Web.Lists.GetByTitle("My Documents");

    CamlQuery camlQuery = new CamlQuery();
    camlQuery.ViewXml = XML;
    ListItemCollection listItems = list.GetItems(camlQuery);
    clientContext.Load(
         listItems,
         items => items.Include(item => item["FileRef"]));

    clientContext.ExecuteQuery();

    // return this file to the user
    // listItems[0];

I am retrieving a document list from a Sharepoint library. Let's say my task is to retrieve the very first document in that list to the user so he can open a docx file. How do I go about doing that?

A further complication is that the sharepoint server is located on another domain. The web project that I am working on will surface the documents to the customer, but not expose direct access to the sharepoint server.

    ClientContext clientContext = new ClientContext(URL);
    List list = clientContext.Web.Lists.GetByTitle("My Documents");

    CamlQuery camlQuery = new CamlQuery();
    camlQuery.ViewXml = XML;
    ListItemCollection listItems = list.GetItems(camlQuery);
    clientContext.Load(
         listItems,
         items => items.Include(item => item["FileRef"]));

    clientContext.ExecuteQuery();

    // return this file to the user
    // listItems[0];

您可以根据此查询的结果创建“A”元素，以便用户只需单击包含项目完整路径的链接（这大约是常规 SharePoint 列表的呈现方式）。

该解决方案的执行摘要如下。生成锚标记时，请包含来自 FileRef 字段的信息，您的文档应为其提供值。这是您稍后将使用的参考字段。

您致电时将使用该参考

        FileInformation fileInformation = Microsoft.SharePoint.Client.File.OpenBinaryDirect(clientContext, reference);

        Stream stream = fileInformation.Stream; 
        if (stream != null)
        {
            documentName = Path.GetFileName(reference);

            return new FileStreamResult(stream, "unknown")
            {
                FileDownloadName = documentName
            };
        }

The executive summary of the solution is as follows. When producing the anchor tags, include information from the FileRef field which your document should have a value for. This is a reference field that you will use later.

you will use the reference when you call

        FileInformation fileInformation = Microsoft.SharePoint.Client.File.OpenBinaryDirect(clientContext, reference);

        Stream stream = fileInformation.Stream; 
        if (stream != null)
        {
            documentName = Path.GetFileName(reference);

            return new FileStreamResult(stream, "unknown")
            {
                FileDownloadName = documentName
            };
        }
