DataContractSerializer.KnownTypes Property

Gets a collection of types that may be present in the object graph serialized using this instance of the DataContractSerializer.

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

member KnownTypes : ReadOnlyCollection<Type>

Property Value

Type: System.Collections.ObjectModel.ReadOnlyCollection(Type)
A ReadOnlyCollection(T) that contains the expected types passed in as known types to the DataContractSerializer constructor.

The KnownTypes property provides the set of known types that are used for serialization and deserialization. For example, if an instance of the Hashtable class contains instances of a Person class, add the Person type to an instance of the List(T) class and use the instance to construct an instance of the DataContractSerializer. If you know of other types to add to the Hashtable, then add those types to the collection.
