Question

How to specify an attribute in XSD so that when C# classes are generated using XSD tool that particular attribute is generated as property with XMLIgnore attribute?

How to tweak XSD or generation of C# code to get something like this,

[Serializable]
public class Person {

    public string Name { get; set; }

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

By definition, XmlIgnore is for things that aren’t related to the xsd, so xsd is never going to generate a member that it doesn’t know about. If you have a requirement to add non-xml-related members to the xsd-generated type, that is where a partial class comes in, i.e. in a separate code file (specifying the name c# namespace):

// additional (non-xsd) members for Person
partial class Person {
    [XmlIgnore]
    public string NickName {get;set;}
}

note that the other .cs file (from the xsd) has the .Name etc
