Question

Is it possible to create a generic method of type T where T has a specific attribute?

E.g.:

public static XmlDocument SerializeObjectToXml<T>(T obj)
{
    //...
}

and I want to serialize only a classes with a Serializable and/or DataContract attribute:

[Serializable]
[DataContract(Name = "viewModel", Namespace = "ns")]
internal class ViewModel
{
    //...
}

I’m afraid no. There are 3 types of constraints: derivation, constructor and reference/value-type.

I believe, you should check for attributes in the method body and if the serializable object doesn’t meet the criteria call a different method to process it.
