Does ServiceStack support binary responses?

Question

Is there any mechanism in ServiceStack services to return streaming/large binary data? WCF's MTOM support is awkward but effective in returning large amounts of data without text conversion overhead.

Answer 1

I love service stack, this litle code was enough to return an Excel report from memory stream

public class ExcelFileResult : IHasOptions, IStreamWriter
{
    private readonly Stream _responseStream;
    public IDictionary<string, string> Options { get; private set; }

    public ExcelFileResult(Stream responseStream)
    {
        _responseStream = responseStream;

        Options = new Dictionary<string, string> {
             {"Content-Type", "application/octet-stream"},
             {"Content-Disposition", "attachment; filename="report.xls";"}
         };
    }

    public void WriteTo(Stream responseStream)
    {
        if (_responseStream == null) 
            return;

        _responseStream.WriteTo(responseStream);
        responseStream.Flush();
    }
}
