public static Byte[] BinaryCompress(Byte[] InputStream)
    {
        using (MemoryStream ms = new MemoryStream())
        {
        using (GZipStream x = new GZipStream(ms, CompressionMode.Compress, true))

            {
                byte[] inputBytes = (byte[])InputStream;
                x.Write(inputBytes, 0, inputBytes.Length);
            }

            return ms.ToArray();
        }

Could you please provide more specific exception by using below code?

  public static Byte[] BinaryCompress(Byte[] InputStream)
        {
            try
            {
                MemoryStream ms = new MemoryStream();
                try
                {
                    GZipStream x = new GZipStream(ms, CompressionMode.Compress, true)
                    byte[] inputBytes = (byte[])InputStream;
                    x.Write(inputBytes, 0, inputBytes.Length);
                }
                catch (Exception ex)
                {
                    Console.Write(ex.StackTrace);
                }
                return ms.ToArray();
            }
            catch (Exception e)
            {
                Console.WriteLine(e.StackTrace);
                throw;
            }

        }
