C# WCF: WCF Service returning a (404) Bad Request when sending an array of items

I am trying to send an array of about 50 elements to a WCF service method, but I'm always receiving a (404) Bad Request error.

I think that it has to do with the message size or something like that, because if I send an empty array it works.

I did some research and added some stuff in the web.config of the WCF but I still can't manage to get this to work.

Can anyone please provide some additional information as to how I can maybe increase the size of the message I can send?

if i send 5 elements of the array, I still get the bad request error – Andreas Grech
then its not the size, try focusing on the contents of your array. – Konstantinos
but, if i send 3, it works; that's why I'm conferenced about the size – Andreas Grech
oh hmm then maybe its size related indeed – Konstantinos

Stupid, stupid me :(

The thing is that I was creating the binding configuration in the web.config like such:

<bindings>
    <wsHttpBinding>
        <binding name="netTcpBindingConfig" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" transactionFlow="false" hostNameComparisonMode="StrongWildcard"  maxBufferPoolSize="524288" maxReceivedMessageSize="6000000">
            <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="6000000" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        </binding>
    </wsHttpBinding>
</bindings>

But then I was not applying the configuration to the endpoint! So, I had to add this to the endpoint tag:

bindingConfiguration="netTcpBindingConfig"

Now it works like a charm.

It's an obvious one but have you tried setting MaxReceivedMessageSize to 65536 and seeing if it still fails?

Your service host should be configured to recieve large set of data, if not, it is either dropped at service level.

  • Add reference to System.Runtime.Serialization.

  • When creating the binding set the message size:

    
return new NetTcpBinding(SecurityMode.None, true)  
{  
    MaxReceivedMessageSize = 99999999,  
    ReaderQuotas = { MaxArrayLength = 99999999 }  
};
