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)

Syntax

Visual Basic (Declaration)

<AttributeUsageAttribute(AttributeTargets.Class Or AttributeTargets.Struct, Inherited := True,  _
    AllowMultiple := True)> _
Public NotInheritable Class KnownTypeAttribute _
    Inherits Attribute

Visual Basic (Usage)

Dim instance As KnownTypeAttribute

[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct, Inherited = true, 
    AllowMultiple = true)]
public sealed class KnownTypeAttribute : Attribute

Remarks

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.

Note:
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.
