Set The “NonSerializedAttribute” To An Auto Property

Question

This cannot be done in C#. Any way to do it?

...

laugh, in case my little pun wasn\'t understood, what I mean is: how can I mark a property in C# as Non

Answer 1

What was said above is right: You can't prevent an auto-implemented property from being serialized by setting an attribute like [NonSerialized]. It just does not work.

But what does work is the [IgnoreDataMember] attribute in case you are working with an WCF [DataContract]. So

[DataContract]
public class MyClass
{
    [DataMember]
    public string ID { get; set; }

    [IgnoreDataMember]
    public string MySecret { get; set; }
}

will get serialized under WCF.

Although since WCF is an opt-in technology, you can also just omit the [IgnoreDataMember] and it will work as well. So maybe my comment is a little academical ;-)
