Azure Storage: File Metadata

I am creating a webjob app to periodically (scheduled) read an azure file share and process files. I am using the C# ApI examples provided but cannot figure out how to get file metadata with my directory listing. I would like to do something as simple as sort files by modified date. Does anyone have an example of fetching metadata with the Listing Files.

 FileResultSegment resultSegment = await share.GetRootDirectoryReference().ListFilesAndDirectoriesSegmentedAsync(token);
 results.AddRange(resultSegment.Results);

Results in no MetaData or Properties defined for the IListFileItem below.

foreach (IListFileItem listItem in results)
            {
                // listItem type will be CloudFile or CloudFileDirectory
                Console.WriteLine("- {0} (type: {1})", listItem.Uri, listItem.GetType());
            }

Building on Thomas's post... This is the only way I have found.

foreach (var item in results)
{
    if (item is CloudFile)
    {
        var cloudFile = (CloudFile) item;
        cloudFile.FetchAttributes();

        // You can now access metadata and properties
        //cloudFile.Metadata
        //cloudFile.Properties
    }
    else if (item is CloudFileDirectory)
    {
        var cloudFileDirectory = (CloudFileDirectory)item;
        // You can now access metadata and properties
        //cloudFileDirectory.Metadata
        //cloudFileDirectory.Properties
    }
}

What about casting your results ?

foreach (var item in results)
{
    if (item is CloudFile)
    {
        var cloudFile = (CloudFile) item;

        // You can now access metadata and properties
        //cloudFile.Metadata
        //cloudFile.Properties
    }
    else if (item is CloudFileDirectory)
    {
        var cloudFileDirectory = (CloudFileDirectory)item;
        // You can now access metadata and properties
        //cloudFileDirectory.Metadata
        //cloudFileDirectory.Properties
    }
}
