Specifies types that should be recognized by the DataContractSerializer when serializing or deserializing a given type.
Assembly: System.Runtime.Serialization (in System.Runtime.Serialization.dll)
'Declaration <AttributeUsageAttribute(AttributeTargets.Class Or AttributeTargets.Struct, Inherited := True, _ AllowMultiple := True)> _ Public NotInheritable Class KnownTypeAttribute _ Inherits Attribute
[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct, Inherited = true, AllowMultiple = true)] public sealed class KnownTypeAttribute : Attribute
The KnownTypeAttribute type exposes the following members.
|KnownTypeAttribute(String)||Initializes a new instance of the KnownTypeAttribute class with the name of a method that returns an IEnumerable of known types.|
|KnownTypeAttribute(Type)||Initializes a new instance of the KnownTypeAttribute class with the specified type.|
|MethodName||Gets the name of a method that returns a list of types that should be recognized during serialization or deserialization.|
|Type||Gets the type that should be recognized during serialization or deserialization by the DataContractSerializer.|
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
Apply the KnownTypeAttribute attribute to a type to indicate to the DataContractSerializer the 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.
In your code, you can use the word KnownType instead of the longer KnownTypeAttribute.
