Assembly: System.Data (in System.Data.dll)
|The serialization format is unknown.|
|The Native serialization format uses a very simple algorithm that enables SQL Server to store an efficient representation of the UDT on disk. Types marked for Native serialization can only have value types (structs in Microsoft Visual C# and structures in Microsoft Visual Basic .NET) as members. Members of reference types (such as classes in Visual C# and Visual Basic), either user-defined or those existing in the framework (such as String), are not supported.|
The requirements for this format are:
|The UserDefined serialization format gives the developer full control over the binary format through the IBinarySerialize.Write and IBinarySerialize.Read methods.|
The aggregate must specify a value for MaxByteSize.
Specify the IsByteOrdered attribute property. The default value is false.
The following example shows the UserDefinedType attribute of the Point UDT. The UDT is byte-ordered, is named "Point", has a validation method named "ValidatePoint", and uses the native serialization format.
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
