The maximum nametable character count quota (16384) has been exceeded while reading XML data

Question

When I am trying to read a meta data I got this error any Idea here is My code

WSHttpBinding binding = new WSHttpBinding(SecurityMode.None);
binding.MaxReceivedMessageSize = Int32.MaxValue; // DPNote: This may actually be too big.  see how it performs.
binding.ReaderQuotas.MaxNameTableCharCount = 99999999;

MetadataExchangeClientMode exchangeMode = MetadataExchangeClientMode.HttpGet; // Default to a HttpGET
metaClient = new MetadataExchangeClient(binding);
metaClient.MaximumResolvedReferences = 10 * 100; //DPNote: Some arbitrary number.  Default is 10, so this is bigger.


if (address.Scheme == "http")
  exchangeMode = MetadataExchangeClientMode.HttpGet;
else if (address.Scheme == "https")
  exchangeMode = MetadataExchangeClientMode.HttpGet;
else
  exchangeMode = MetadataExchangeClientMode.MetadataExchange;

MetadataSet metadata = metaClient.GetMetadata(address, exchangeMode);
MetadataImporter importer = new WsdlImporter(metadata);

and this is the line which throws the error

MetadataSet metadata = metaClient.GetMetadata(address, exchangeMode);

Answer 1

Have you tried incrementing any of these other values inside of binding.ReaderQuotas beyond their default values:

maxDepth, maxStringContentLength, maxArrayLength, maxBytesPerRead?

It could also be the maxBufferPoolSize of the binding

Answer 2

This is a error in Microsoft code,Http-Get not support Reader Quotas, so we can do this

      var smAsm = AppDomain.CurrentDomain.GetAssemblies().First(a => a.FullName.StartsWith("System.ServiceModel,"));
        var defTy = smAsm.GetType("System.ServiceModel.Channels.EncoderDefaults");
        var rq = (System.Xml.XmlDictionaryReaderQuotas)defTy.GetField("ReaderQuotas", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.NonPublic).GetValue(null);
        rq.MaxArrayLength = int.MaxValue;
        rq.MaxDepth = int.MaxValue;
        rq.MaxNameTableCharCount = int.MaxValue;
        rq.MaxStringContentLength = int.MaxValue;
