Use this method to examine the custom attributes of code in the reflection-only context, in cases where the custom attributes themselves are defined in code that is loaded into the reflection-only context. Methods like erload:System.Attribute.GetCustomAttributes and erload:System.Reflection.MemberInfo.GetCustomAttributes cannot be used in such cases, because they create instances of the attributes. Code in the reflection-only context cannot be executed. For more information and for example code, see the System.Reflection.CustomAttributeData class.

This method gets custom attribute data for types, nested types, and type members, because the Type class and the classes in the System.Reflection namespace that represent type members all derive from System.Reflection.MemberInfo.
