Calculate size of a package(datacontract) that goes over WCF?

Is it possible to calculate the size of a (complexed) object (with dataContract) that I send over WCF? What I need is to calculate the size on both the request and the response objects and I need to do this in a winform application.

Could I maybe serlize the objects and then get the total size?

You can manually serialise / deserialise the objects yourself. Here's a simple example of serialisation and obtaining the length.

[DataContract(Name = "Person", Namespace = "http://www.woo.com")]
    class Person
    {
        [DataMember()]
        public string Name;
        [DataMember()]
        public int Age;        
    }

calling code (in a console app)

        Person p = new Person();
        p.Name = "Sean Cocteau";
        p.Age = 99;

        DataContractSerializer ds = new DataContractSerializer(p.GetType());

        using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
        {
            ds.WriteObject(ms, p);                
            // Spit out

            Console.WriteLine("Output: " + System.Text.Encoding.UTF8.GetString(ms.ToArray()));
            Console.WriteLine("Message length: " + ms.Length.ToString());
        }

        Console.ReadKey();

In respect to performing this automatically, say on each WCF call may involve you having to create your own Custom Binding that adds this to the message.

You can use svctraceviewer to trace both the activity and the message and then you can see the actual message flowing over WCF. However it seems that this tool might not get you the total size.

This post might help.

I think a message interceptor will help, you can add this endpoint behavior to the endpoint and handle httpwebrequest/response.

For more information, google WCF Message Interceptor, you'll find lots of useful things.

Hope this will help.
