Remarks
The metadata may be class-level metadata or metadata associated with a DependencyProperty or MemberDescriptor. The designer uses this method to identify loaded types that need a Refreshed event raised when a new attribute table is added, and to quickly decide which tables should be queried further during attribute queries.
Examples
The following code example shows how to use the ContainsAttributes method to determine whether a type has custom attributes. This code example is part of a larger example provided for the AttributeTable class.
Dim hasCustomAttributes As Boolean = attributes.ContainsAttributes(GetType(Button))
bool hasCustomAttributes = attributes.ContainsAttributes(typeof(Button));
