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

错误

Maximum number of items that can be serialized or deserialized in an object graph is '65536'. Change the object graph or increase the MaxItemsInObjectGraph quota. 

解决

服务器端：

ServiceHost host = new ServiceHost(serviceType, uri);
foreach (IServiceBehavior behavior in host.Description.Behaviors)
{
if (behavior is ServiceBehaviorAttribute)
{
(behavior as ServiceBehaviorAttribute).MaxItemsInObjectGraph = int.MaxValue;
}
}

 

客户端：

ChannelFactory<T> channelFactory = new ChannelFactory<T>(binding);
foreach (OperationDescription op in channelFactory.Endpoint.Contract.Operations)
{
DataContractSerializerOperationBehavior dataContractBehavior = op.Behaviors.Find<DataContractSerializerOperationBehavior>() as DataContractSerializerOperationBehavior;
if (dataContractBehavior != null)
{
dataContractBehavior.MaxItemsInObjectGraph = int.MaxValue;
}
}
