Format Enumeration
Used by SqlUserDefinedTypeAttribute and SqlUserDefinedAggregateAttribute to indicate the serialization format of a user-defined type (UDT) or aggregate.
Assembly: System.Data (in System.Data.dll)
| Member name | Description | |
|---|---|---|
| Unknown | The serialization format is unknown. | |
| Native | 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:

| UserDefined | 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. If you omit any field in the Read or Write methods, the state of that field is not serialized. |
