Hi,

I am having one lakh record in my datatable while compress and de compress and after serialize i am getting Exception of type 'System.OutOfMemoryException' was throw

I AM USING WCF+WPF

My Code is

public static MemoryStream DataTableSerialization(DataTable dtSearchDataTable)
{
    System.IO.MemoryStreamstream = newSystem.IO.MemoryStream();
 
    System.Runtime.Serialization.IFormatterformatter = newSystem.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
    byte[] bytes = null;

    MemoryStream memory = new MemoryStream();  

    try
    {
        dtSearchDataTable.RemotingFormat = SerializationFormat.Binary;
        
        formatter.Serialize(stream, dtSearchDataTable);//Here i am getting error 
        bytes = stream.ToArray();
        
        using (vargzip = newGZipStream(memory, CompressionMode.Compress, true))
        {
            gzip.Write(bytes, 0, bytes.Length);
        }
        
        memory.Position = 0; 
        
        // ---  In order to enable reading option during Deserialzation on client side we need to set Position = 0
        }
    catch(Exceptionex)
    {  
    } 
    finally
    
    {
        stream.Dispose();
        MinimizeMemory();
    }            

    return memory;
}

My Webconfig(WCF)

Added code tags. Didn't even try to correctly format the web.config part though, it's an incomplete snippet. Please sort that out.
