How to exclude certain properties in gerilization

[authera]

I'm trying to show the object with a few properties, but I don't want to turn all the properties on the show.

Of course I could use an attribute. [XmlIgnore]but I need to be able to do

The question is how to exclude certain properties when servilization does not change the reference class, and it would be desirable to have a rigorous typology.

Thank you.

This can be done as follows.

We'll use the ready class. XmlAttributeOverrides but we'll do a couple of extension techniques to add strict typology:

public static class XmlAttributeOverridesHelpers
{
    public static void Add<T>(this XmlAttributeOverrides overrides, Expression<Func<T, dynamic>> propertySelector, XmlAttributes attributes)
    {
        overrides.Add(typeof(T), propertySelector.BuildString(), attributes);
    }
public static string BuildString(this Expression propertySelector)
{
    switch (propertySelector.NodeType)
    {
        case ExpressionType.Lambda:
            LambdaExpression lambdaExpression = (LambdaExpression)propertySelector;
            return BuildString(lambdaExpression.Body);

        case ExpressionType.Convert:
        case ExpressionType.Quote:
            UnaryExpression unaryExpression = (UnaryExpression)propertySelector;
            return BuildString(unaryExpression.Operand);

        case ExpressionType.MemberAccess:

            MemberExpression memberExpression = (MemberExpression)propertySelector;
            MemberInfo propertyInfo = memberExpression.Member;

            if (memberExpression.Expression is ParameterExpression)
            {
                return propertyInfo.Name;
            }
            else
            {
                // we've got a nested property (e.g. MyType.SomeProperty.SomeNestedProperty)
                return BuildString(memberExpression.Expression) + "." + propertyInfo.Name;
            }

        default:
            // drop out and throw
            break;
    }
    throw new InvalidOperationException("Expression must be a member expression: " + propertySelector.ToString());
}

}

May be applied as follows:

var overrides = new XmlAttributeOverrides();

var ignore = new XmlAttributes { XmlIgnore = true };

overrides.Add<MyClass>(m => m.Id, ignore);

overrides.Add<MyClass>(m => m.DateChanged, ignore);

Type t = typeof(List<MyClass>);

XmlSerializer serial = new XmlSerializer(t, overrides);
