  NameDescription
Public propertyCountGets the number of objects in the referenced collection. (Inherited from SmoCollectionBase.)
Public propertyIsSynchronizedGets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (Inherited from SmoCollectionBase.)

Public propertyItem(String)Gets a UserDefinedType object in the collection by name.
Public propertyItem(String, String)Gets a UserDefinedType object in the collection by name and schema.
