Hi All,
I am trying to process messages from the service bus queue. So basically my handler unzips the message and process. I have come with the below to unzip but i seeing a lot of messages sitting int he dead letter queue with the error message "the underlying compression routine could not reserve sufficient memory". Appreciate if you could please comment on the code below? App insights failures are pointing me to the Unzip method below.
public static class StringCompression
{
public static void CopyTo(Stream src, Stream dest)
{
var bytes = new byte[4096];
int cnt;
while ((cnt = src.Read(bytes, 0, bytes.Length)) != 0)
{
dest.Write(bytes, 0, cnt);
}
}
public static string Unzip(byte[] bytes)
{
using (var msi = new MemoryStream(bytes))
using (var mso = new MemoryStream())
{
using (var gs = new GZipStream(msi, CompressionMode.Decompress))
{
//gs.CopyTo(mso);
CopyTo(gs, mso);
}
return Encoding.UTF8.GetString(mso.ToArray());
}
}
public static byte[] Zip(string str)
{
var bytes = Encoding.UTF8.GetBytes(str);
using (var msi = new MemoryStream(bytes))
using (var mso = new MemoryStream())
{
using (var gs = new GZipStream(mso, CompressionMode.Compress))
{
//msi.CopyTo(gs);
CopyTo(msi, gs);
}
return mso.ToArray();
}
}
}
