POGZipStream over .NET webservice causes invalid character issue
text
Body
copied!<p>I'm working on a complex .NET client server architecture customization and I absolutely have no control over request/reply sent or received except that I can add my stuff to the request/reply objects.</p> <p>I've a dataset on server side to be sent to client andI'm using GZipStream to compress the dataset. The compression works fine, but when the reply is received on client end, I get invalid character exception - 0x1F. I googled and could not find appropriate resource to address this issue. </p> <p>Compression code: </p> <pre><code>Private Function Compress(ByVal data() As Byte) As Byte() Try '---the ms is used for storing the compressed data--- Dim ms As New MemoryStream() Dim zipStream As Stream = Nothing zipStream = New GZipStream(ms, _ CompressionMode.Compress, True) '---or--- 'zipStream = New DeflateStream(ms, _ ' CompressionMode.Compress, True) '---compressing using the info stored in data--- zipStream.Write(data, 0, data.Length) zipStream.Close() ms.Position = 0 '---used to store the compressed data (byte array)--- Dim compressed_data(CInt(ms.Length - 1)) As Byte '---read the content of the memory stream into ' the byte array--- ms.Read(compressed_data, 0, CInt(ms.Length)) Return compressed_data Catch ex As Exception Return Nothing End Try End Function </code></pre> <p>Any idea to fix this issue considering the fact that I can alter the request/response handling mechanism is really appreciated. In addition, I also request any ideas on better ways handling large dataset transfers over webservice. Thank you.</p>
