# SerializedDictionary

Class in [Yarn.Unity](/2.2/api/csharp/yarn.unity.md)

Inherits from `IDictionary`2\`

## Summary

An `IDictionary<TKey,TValue>` that can be serialized as part of a Unity object.

```csharp
public class SerializedDictionary<TKey, TValue> : IDictionary<TKey, TValue>, ISerializationCallbackReceiver
```

## Remarks

Prior to Unity 2020, dictionaries cannot be directly serialized by Unity. This class is a workaround; it provides an API identical to `Dictionary<TKey, TValue>` , and stores its contents as two `List<T>` s: one for `TKey` , and one for `TValue` .

## Type Parameters

| Name   | Description                               |
| ------ | ----------------------------------------- |
| TKey   | The type of key used in the dictionary.   |
| TValue | The type of value used in the dictionary. |
