Assembly: mscorlib (in mscorlib.dll)
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 Attribute.GetCustomAttributes and Assembly.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 CustomAttributeData class.
