KnownTypeAttribute Class

Specifies types that should be recognized by the DataContractSerializer when serializing or deserializing a given type.

Namespace:  System.Runtime.Serialization
Assembly:  System.Runtime.Serialization (in System.Runtime.Serialization.dll)

public final class KnownTypeAttribute extends Attribute

Apply the KnownTypeAttribute attribute to a type to indicate to the DataContractSerializer types that should be recognized when serializing or deserializing an instance of the type to which the attribute is applied. This attribute could also be recognized by other serializers that understand data contracts.

NoteNote:

In your code, you can use the word KnownType instead of the longer KnownTypeAttribute.

You can either apply exactly one KnownTypeAttribute instance with the MethodName property set, or one or more KnownTypeAttribute instances with the Type property set.

The following example shows a type named Person and a type named IDInformation that should be recognized when serializing or deserializing the Person type.

No code example is currently available or this language may not be supported.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
