Are you sure the stream is looking at the right place? I.e. if you just go Serialize, Deserialize on the same stream, it will still have the pointer at the end; you need to seek to the beginning (stream.Seek(0, SeekOrigin.Begin)).

In case you're using the same stream for deserialization and serialization, make sure to set your stream back to position 0.

C#

public static DataSet Deserialize(Stream stream)
        {
            BinaryFormatter serializer = new BinaryFormatter();
            stream.Position=0;
            return (DataSet)serializer.Deserialize(stream);
        }
