How to get metadata custom attributes?

Question

I have a class that defines data annotations at class level. The meta data class has custom attributes associated with it, along with the usual DisplayName,

Answer 1

Have you tried just doing this,

public class BaseViewModel
{
    [DisplayName("Id")]
    public int Id { get; set; }

    [DisplayName("Selected")]
    [ExportItem(Exclude = true)]
    public bool Selected { get; set; }
}

You can then use a variation of your code,

var type = typeof(T);    
var propertyMetaData = type.GetProperties()
    .Select(property => 
        property.GetCustomAttributes(typeof(ExportItemAttribute), false)
                .FirstOrDefault() as ExportItemAttribute)
    .Where(attribute => attribute == null || !attribute.Exclude)
    .ToList();
