title: How can I ignore a property when serializing using the DataContractSerializer?
body: <p>I am using .NET 3.5SP1 and <code>DataContractSerializer</code> to serialize a class.  In SP1, they changed the behavior so that you don't have to include <code>DataContract</code>/<code>DataMember</code> attributes on the class and it will just serialize the entire thing.  This is the behavior I am using, but now I need to ignore one property from the serializer.  I know that one way to do this is to add the <code>DataContract</code> attribute to the class, and just put the <code>DataMember</code> attribute on all of the members that I want to include.  I have reasons, though, that this will not work for me.</p>
  <p>So my question is, is there an attribute or something I can use to make the <code>DataContractSerializer</code> ignore a property?</p>
