如何将文档从Sharepoint文档库返回给用户？

Question

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];

Answer 1

您可以基于此查询的结果创建“ A”元素，以便用户只需单击具有该项目完整路径的链接即可（这大约是呈现常规SharePoint列表的方式）。

Answer 2

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
            };
        }
