# InMemoryVariableStorage

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

Inherits from [`VariableStorageBehaviour`](/api/csharp/yarn.unity/yarn.unity.variablestoragebehaviour.md)

## Summary

A simple implementation of VariableStorageBehaviour.

```csharp
public class InMemoryVariableStorage : VariableStorageBehaviour, IEnumerable<KeyValuePair<string, object>>
```

## Remarks

This class stores variables in memory, and is erased when the game exits.

This class also has basic serialization and save/load example functions.

You can also enumerate over the variables by using a `foreach` loop:

```
// 'storage' is an InMemoryVariableStorage
foreach (var variable in storage) {
string name = variable.Key;
System.Object value = variable.Value;
}
```
