Adding C# attribute to wsdl.exe generated property?

Question

I have a class which is automatically generated via wsdl.exe, I need to add the [System.Xml.Serialization.XmlIgnoreAttribute()] attribute to one of the properties, but I can't modify the class directly as it is regenerated every now and then.

Is there any way to do this? I already tried searching for solutions with inheritance, partial classes and reflection but without luck. I'm stuck with .NET Framework 2.0 because of customer's constraints.

(more details on why I need to do this here: Prevent timezone conversion on deserialization of DateTime value , I'm adding the string property in a partial class)

EDIT: A requested code snippet is a simple as this:

[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.3038")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://common.ws.model.plx.ids.it/")]
public partial class publication {
    private System.DateTime dateFromField;

    //[System.Xml.Serialization.XmlIgnoreAttribute()] I would like to add this
    [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public System.DateTime dateFrom {
        get {
            return this.dateFromField;
        }
        set {
            this.dateFromField = value;
        }
    }

    ///// This method has been moved in the other partial class
    //[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified, ElementName = "dateFrom")]
    //public string dateFromString
    //{
    //    get
    //    {
    //        return XmlConvert.ToString(dateFrom, XmlDateTimeSerializationMode.RoundtripKind);
    //    }
    //    set
    //    {
    //        dateFrom = DateTimeOffset.Parse(value).DateTime;
    //    }
    //}
}

You can use postsharp to dynamically add missing attributes to properties. Have a look at How to inject an attribute using a PostSharp attribute? .

It shows how you can apply the XmlIgnore attribute to every public property, but you can change the aspect code to have different behavior in your case.
