Handling incoming streams in WCF when transmode is set to streaming

StreamManager.cs

public class StreamManager
{
  private const int BufferLength = 1024;
  /// <summary>
  /// Receives the sourceStream from service and iterate until end of the stream
  /// </summary>
  /// <param name="sourceStream">Source stream</param>
  /// <returns>Memory stream</returns>
  public MemoryStream ReadStream(Stream sourceStream)
  {
    var destinationStream = new MemoryStream();
    var byt = new byte[BufferLength];
    int count = 0;
    while ((count = sourceStream.Read(byt, 0, BufferLength)) > 0)
    {
      destinationStream.Write(byt, 0, count);
    }
    destinationStream.Position = 0;
    sourceStream.Dispose();
    return destinationStream;
    
  }
