How to Copy One Stream To Another in C#

 

This C# method will help you to copy a given stream file to another stream file.  Just pass the source and destination streams and you will get stream copied into destination one.

       /// <summary>
       /// Copies the contents of one stream to another.
       /// </summary>
       /// <param name="source">The stream to copy from</param>
       /// <param name="dest">The destination stream</param>
       /// <remarks>Copying starts at the current stream positions</remarks>
       public static void CopyStreams(Stream source, Stream dest)
       {
           byte[] buffer = new byte[64 * 1024];

           int nRead = source.Read(buffer, 0, buffer.Length);
           while (nRead != 0)
           {
               dest.Write(buffer, 0, nRead );
               nRead = source.Read(buffer, 0, buffer.Length);
           }
       }
