Enabling readerQuotas on WCF GZip Encoder Custom Binding

I have enabled compression of my WCF service by implementing the sample GZip encoder featured on on MSDN and everyth开发者_JAVA技巧ing is working great, however now need to transfer my reader quotas across to this binding, as I previously had these customised when I was using wsHttpBinding.

This is my GZip binding as declared in my Web.config of the wcf service:

  <customBinding>
    <binding name="BufferedHttpCompressionBinding" closeTimeout="00:00:15"
      openTimeout="00:00:15" receiveTimeout="00:00:15" sendTimeout="00:00:15">
      <gzipMessageEncoding innerMessageEncoding="textMessageEncoding">
      </gzipMessageEncoding>
      <httpTransport maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
        maxBufferSize="2147483647">
        <extendedProtectionPolicy policyEnforcement="Never" />
      </httpTransport>
    </binding>
  </customBinding>

As you can see without the reader quotas, now here are the readerQuotas that I would like to add:

<readerQuotas
              maxDepth="64"
              maxStringContentLength="1048576"
              maxArrayLength="1048576"
              maxBytesPerRead="1048576"
              maxNameTableCharCount="1048576" />   

I have tried inserting this node as a child of the <binding /> element, and also I saw an example online of it between the <gzipMessageEncoding /> element, neither of the two work for me returning an error:

System.Configuration.ConfigurationErrorsException: Unrecognized element 'readerQuotas'.

Any thoughts? Is it possible to use reader quotas with custom bindings? I imagine it would have to be, but might this be a class change, or a simple way to get it going through config? Hopefully some WCF whiz can help :)

Many thanks, Graham.

Have a look at this thread http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/633c5dc8-c134-40c9-9dfc-41a4b1cd3279/

You have to modify GZipMessageEncodingElement and GZipMessageEncodingBindingElement to expose readerQuotas...

I was able to do this programmatically:

var gzipBindingElement = new GZipMessageEncodingBindingElement();
myBinding.ReaderQuotas.CopyTo((TextMessageEncodingBindingElement)gzipBindingElement.InnerMessageEncodingBindingElement).ReaderQuotas);
