Modify endpoint ReaderQuotas programatically

Question

Hi,

I have a dynamic client to a service. How can i change the ReaderQuotas property of it's endpoint binding?

I tried like this but it doesn't work ....

DynamicProxyFactory factory = new DynamicProxyFactory(m_serviceWsdlUri);

         foreach (ServiceEndpoint endpoint in factory.Endpoints)
         {
             Binding binding =  endpoint.Binding;

             binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxArrayLength = 2147483647
             binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxBytesPerRead =2147483647;
             binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxDepth = 2147483647;
             binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxNameTableCharCount = 2147483647;
             binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxStringContentLength = 2147483647;
}

Even after doing this the ReaderQuotas values remain the default ones.

I also tried like this and still doesn't work:

 DynamicProxyFactory factory = new DynamicProxyFactory(m_serviceWsdlUri);

             foreach (ServiceEndpoint endpoint in factory.Endpoints)
             {
                 System.ServiceModel.Channels.BindingElementCollection bec = endpoint.Binding.CreateBindingElements();

                 System.ServiceModel.Channels.TransportBindingElement tbe = bec.Find<System.ServiceModel.Channels.TransportBindingElement>();

                 tbe.MaxReceivedMessageSize = 2147483647;
                 tbe.MaxBufferPoolSize = 2147483647;
                 TextMessageEncodingBindingElement textBE = bec.Find<TextMessageEncodingBindingElement>();

                 if (textBE != null)
                 {

                     textBE.ReaderQuotas.MaxStringContentLength = 2147483647;
                     textBE.ReaderQuotas.MaxArrayLength = 2147483647;
                     textBE.ReaderQuotas.MaxBytesPerRead = 2147483647;
                     textBE.ReaderQuotas.MaxDepth = 2147483647;
                     textBE.ReaderQuotas.MaxNameTableCharCount = 2147483647;

                 }
    }

I need this so i can send more than 8kb to the service.

Need help please, and some example if possible...

Thanks, Adrya

Answer 1

Setting quotas on a BindingElement after the binding is created has no effect on that binding.

Edit (since you don't know what binding is used):

You can use reflection to set the property. Note you should make sure the Binding actually has the property before setting it. Not all bindings have this property. If you try to set it on a binding that doesn't support it, the example will throw an exception.

Binding binding = endpoint.Binding;

XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
myReaderQuotas.MaxStringContentLength = _sanebutusablelimit_;
myReaderQuotas.MaxArrayLength = _sanebutusablelimit_;
myReaderQuotas.MaxBytesPerRead = _sanebutusablelimit_;
myReaderQuotas.MaxDepth = _sanebutusablelimit_;
myReaderQuotas.MaxNameTableCharCount = _sanebutusablelimit_;

binding.GetType().GetProperty("ReaderQuotas").SetValue(binding, myReaderQuotas, null);

Hope this helps you a bit.

Answer 2

Why are you solving that in a such complex way, just alter the ReaderQuotas directly:

ie:

WSHttpBinding WebBinding = new WSHttpBinding();

WebBinding.ReaderQuotas.MaxArrayLength = int.MaxValue; WebBinding.ReaderQuotas.MaxStringContentLength = int.MaxValue; WebBinding.ReaderQuotas.MaxBytesPerRead = int.MaxValue;

This will work without that weird reflection sample.
