Hide public Property when exposed through web service.

Question

I would like to prevent a property from being exposed via my WCF web service. I tried adding the XmlIgnore attribute bug that didn't work. We are using .NET 3.5. WCF.

This doesn't work:

    public class MyClass
    {
        public string S1 { get; set; }

        [XmlIgnore]
        public string S2NotExposed { get; set; }
    }

Answer 1

Mark your class with the [DataContract] attribute from the DataContractAttribute Class , then mark only the properties you want to expose with the [DataMember] attribute from the DataMemberAttribute Class.
