SharpZipLib Inflate caused Unexpected Eof C#

I am working in C# and using SharpZipLib as I am working with Silverlight and .NET.  I want to compress a file and decompress it prior to transfer to make sure that the file size is the same after decompression, just to catch any compression errors.  I have attached my code.  When I inflate the stream, the InflatorInputStream has zero length and I get an error "Unexpected Eof" when I try to read from the InflatorInputStream.  I have reset the position and all the online examples of decompressing a stream are all same.  Am I missing something?  
Just to add that I was using a small text file while testing.

private byte[] CompressFile(byte[] bytesIn)
        {
            MemoryStream ms = new MemoryStream();
            
            ICSharpCode.SharpZipLib.Zip.Compression.Deflater defl = new ICSharpCode.SharpZipLib.Zip.Compression.Deflater(9, false);
            Stream s = new DeflaterOutputStream(ms, defl);
            s.Write(bytesIn, 0, bytesIn.Length);
            
            byte[] compressedData = (byte[])ms.ToArray();
            ms.Position = 0;
            MemoryStream ms2 = new MemoryStream(compressedData);
            ms2.Position = 0;
            ICSharpCode.SharpZipLib.Zip.Compression.Inflater inf = new ICSharpCode.SharpZipLib.Zip.Compression.Inflater(false);
            InflaterInputStream s2 = new InflaterInputStream(ms2, inf);
           
            byte[] decompressedBuffer = new byte[32768];
            int totalCount = ReadAllBytesFromStream(s2, decompressedBuffer);
            if (!CompareData(bytesIn, bytesIn.Length, decompressedBuffer, totalCount))
            {
                throw new Exception("Error when compressing the file");
            }
            s.Close();
            s2.Close();

            return compressedData;
        }


        public int ReadAllBytesFromStream(InflaterInputStream stream, byte[] buffer)
        {
            int offset = 0;
            int totalCount = 0;
            while (true)
            {
                int bytesRead = stream.Read(buffer, offset, buffer.Length);
                if (bytesRead <= 0)
                {
                    break;
                }
                offset += bytesRead;
                totalCount += bytesRead;
            }
            return totalCount;
        }
