Biztalk custom send pipeline Using memory stream

Question

Hi friends,
I developing the custom send pipeline,I am calling the custom helper class.The helper class I am using the Memory stream.
The helper class method is looks like:
public MemoryStream UpdateProcess(MemoryStream ms)
In the pipeline i need to call this method 
 public IBaseMessage Execute(IPipelineContext pc, IBaseMessage inmsg)
                    //To get Incoming message
            System.IO.Stream originalStream = inmsg.BodyPart.GetOriginalDataStream();
            //Working with XDocument
            XDocument xDoc;
            using (XmlReader reader = XmlReader.Create(originalStream))
                reader.MoveToContent();
                xDoc = XDocument.Load(reader);
            // Returning stream
            byte[] output = System.Text.Encoding.ASCII.GetBytes(xDoc.ToString());
            MemoryStream memoryStream = new MemoryStream();
            memoryStream.Write(output, 0, output.Length);
            ProcessHelper mf = new ProcessHelper();
            mf.UpdateProcess(memoryStream);
            memoryStream.Position = 0;
            inmsg.BodyPart.Data = memoryStream;
            return inmsg;
            catch (Exception ex)
                throw ex;
            finally
                if (parms != null)
                    parms.Clear();
            return inmsg;
Can you can any one let me know i am doing correct logic in pipeline component.
Thanks

Realistically, we can say for sure if it's right since we don't know the implementation of the helper.
However, since it looks like the helper expects a MemoryStream with Xml content, you can probably just copy the data from the original stream to the local MemoryStream.  Passing it through an XmlDocument might be unnecessary.
Also, unless you are absolutely sure the source document is ASCII, you shouldn't use ASCII encoding since you can loose meaningful character data.
