I am writing code for a custom control. I have created a ConverterAttribute to convert the value in the property to something else. My CustomAttribute can be applied multiple times to a single property that allows conversion of a collection. Say I want to have a converter for the actual collection and a converter for the items in the collection, I need to get these two ConverterAttributes. How do you get an attribute array (CustomAttribute[]) from the PropertyDescriptor? I know you can do prop.Attributes[typeof(CustomAttribute)], but that only returns a single attribute and I need all of them on the property to build my object serializer.

Hi.

What exactly are you trying to do by applying more than one instance of the same attribute to a property? The code for doing that won't even compile. However theoretically if you do have multiple instances of the same attribute applied to a class or member, you can retrieve them through GetCustomAttributes(typeof(<custom attribute type>)) method of Type or MemberInfo. The Descriptor classes in System.ComponentModel are only components that utilize reflection through their various methods and properties.

Hope this helps.
