[WCF]Maximum number of items that can be serialized or deserialized in an object graph is '65536'

I got this error while invoking a web service server with a WCF client.

This error message indicates that the data is too large and exceed max. serialize/deserialize object limit.

To resolve this, we need to modify maxItemsInObjectGraph attribute in <dataContractSerializer> on both client side and server side.

To accomplish this via xml configuration file, add the following lines on server web.config:

<serviceBehaviors>
<dataContractSerializer maxItemsInObjectGraph="2147483647" />
</serviceBehaviors>

And on client

<endpointBehaviors>
<behavior name="somename">
<dataContractSerializer maxItemsInObjectGraph="2147483647"/> 
...

To accomplish this via code on the server:
foreach (IServiceBehavior behavior in selfHost.Description.Behaviors)
{
    try
    {
        if(behavior is DataContractSerializerOperationBehavior){
            ((DataContractSerializerOperationBehavior)behavior).MaxItemsInObjectGraph = int.MaxValue;
        }
    }
    catch { }                        
}

on the client:

foreach (OperationDescription operation in pipeFactory.Endpoint.Contract.Operations)
{
    foreach (IOperationBehavior behavior in operation.Behaviors)
    {
        try
        {
            if(behavior is DataContractSerializerOperationBehavior){
              ((DataContractSerializerOperationBehavior)behavior).MaxItemsInObjectGraph = int.MaxValue;
          }
        }
        catch { }  
    }
}

And Since my server is a traditional web service, I don’t need to modify server codes (at least for my case).
