Attributes and Elements
The following sections describe attributes, child elements, and parent elements.
Attributes
| 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. |
index Attribute
| 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". |
Child Elements
None.
Parent Elements
| Element | Description |
|---|---|
| <knownType> | Specifies a known type that can be returned by a field or property of the declared type. |
