SqlUserDefinedTypeAttribute Class
Used to mark a type definition in an assembly as a user-defined type (UDT) in SQL Server. The properties on the attribute reflect the physical characteristics used when the type is registered with SQL Server. This class cannot be inherited.
Assembly: System.Data (in System.Data.dll)
SQL Server creates a user-defined type that is bound to the type definition that has the SqlUserDefinedTypeAttribute custom attribute. Every UDT must be annotated with this attribute. See "CLR User-Defined Types" in SQL Server 2005 Books Online for more information about UDTs as well as an example of an UDT.
