正在从上载到Sharepoint 2013 DocumentLibrary的文件获取Id

我有此功能，可以将文件上载到Sharepoint 2013文档库中。我希望能够检索新创建的文档库条目Id

 public void UploadFileToSharePoint(string file)
    {
        ClientContext context = new ClientContext("http://test-sp01");
        Web web = context.Web;

        FileCreationInformation newFile = new FileCreationInformation();
        newFile.Content = System.IO.File.ReadAllBytes(file);
        newFile.Url = System.IO.Path.GetFileName(file);

        List docs = web.Lists.GetByTitle("TestDocumentLibrary");
        Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);

        context.Load(uploadFile);

        context.ExecuteQuery();
    }

获取一个值，该值指定与文件对应的列表项的列表项字段值

例如：

context.Load(uploadFile,f => f.ListItemAllFields) ;
context.ExecuteQuery();
//Print List Item Id
Console.WriteLine("List Item Id: {0}", uploadFile.ListItemAllFields.Id);
