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)
A required attribute on a user-defined type (UDT), used to confirm that the given type is a UDT and to indicate the storage format of the UDT.
The serialization format as a Format.
Indicates whether the user-defined type is byte ordered.
Indicates whether all instances of this user-defined type are the same length.
The maximum size of the instance, in bytes.
The SQL Server name of the user-defined type.
The name of the method used to validate instances of the user-defined type.
This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)
Returns the hash code for this instance.(Inherited from Attribute.)
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)
Returns a string that represents the current object.(Inherited from Object.)
|_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)|
Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)
|_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)|
Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)
Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)
|_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)|
Provides access to properties and methods exposed by an object.(Inherited from Attribute.)
SQL Server creates a user-defined type that is bound to the type definition that has the CLR User-Defined Types for more information about UDTs, including an example of a UDT.custom attribute. Every UDT must be annotated with this attribute. See
