    }

    [ActivityOutput, ActivityFilter]  
    public long Length
    {
        get { return fileInfo.Length; }
    }

    [ActivityOutput, ActivityFilter]
    public DateTime CreationTime
    {
        get { return fileInfo.CreationTime; }
    }

    [ActivityOutput, ActivityFilter]
    public DateTime LastWriteTime
    {
        get { return fileInfo.LastWriteTime; }
    }

    [ActivityOutput, ActivityFilter]
    public bool ReadOnly
    {
        get { return (fileInfo.Attributes & FileAttributes.ReadOnly) != 0; }
    }
}

[Activity]
public class GetDirectory : IActivity
{
    public void Design(IActivityDesigner designer)
    {
        designer.AddInput("Directory").WithFolderBrowser();
        designer.AddCorellatedData(typeof(FileInfoAdapter));
    }

    public void Execute(IActivityRequest request, IActivityResponse response)
    {
        DirectoryInfo dir = request.Inputs["Directory"].As<DirectoryInfo>();
        ICollection files = request.Filters.Filter(FindFiles(dir));
        response.Publish("Number of Files", files.Count);
        response.PublishRange(files);            
    }

    private IEnumerable FindFiles()
    {
        foreach (FileInfo info in path.GetFiles("*.*"))
        {
            yield return new FileInfoAdapter(info);
        }
    }        
}

Remarks

When you add a type marked with the ActivityData attribute the designer will automatically add all of the ActivityInput, ActivityFilter and ActivityOutput properties encapsulated in the type.
