<configuration>
  <system.runtime.serialization>

          <knownType>

Syntax

<parameter index="Integer"
           type="String" />

The following sections describe attributes, child elements, and parent elements.

Attribute	Description
index	When the declared type is a generic type, specifies the generic parameter that will return the known type.
type	A string that describes the known type used for serialization and deserialization.

Value	Description
"0"	The first parameter in the generic type. For example, a List<T> has only one parameter. If it is used as the declared type, the index would be set to "0".
"1"	The second parameter in a generic type. For example, a Dictionary<TKey,TValue> has two parameters. If the known type is returned by the second parameter, set the index attribute to "1".

None.

Element	Description
<knownType>	Specifies a known type that can be returned by a field or property of the declared type.

For more information about known types, see Data Contract Known Types and DataContractSerializer.

See the <dataContractSerializer> for an example of using this element.

This configuration element cannot have both attributes at the same time. If both attributes are set, a ConfigurationErrorsException occurs.
