This is a recurring problem with people getting to grips with WCF.

The bit I think you're missing is maxItemsInObjectGraph. But the following article discusses the wider configuration requirements for WCF requests with large amounts of data.

I had change my server side config according to your link.But still i have found a new error "The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state"

That error message has nothing to do with the object graph size. That error message is a generic error message presented by the client. It means there's a problem with your service and your client can't communicate with it. You need to take a further look at the configuration of your service.

Hi Stephen,

Thanks for reply again.Now I was not doing any changes in config file and run again this code i had still found "The remote server returned an unexpected response: (400) Bad Request." this error.Can you give me more suggestion...

The following is an article about enabling tracing in WCF. Try this, it should provide with more information about your error. http://stackoverflow.com/questions/9897201/how-do-i-investigate-wcf-giving-400-bad-request-over-get

I have added "system.diagnostics......................... system.diagnostics"
in config file and also added "Error.svclog" viewer but error will be not traced by this.

I found the answer to the Bad Request 400 problem.

It was the default server binding setting. You would need to add to server and client default setting.

binding name="" openTimeout="00:10:00" closeTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">
