```csharp
public object ReadValue<TInput>(ref Reader<TInput> reader, Field field)
```

Reads a value and returns it untyped. The type must still match the codec instance!

### Parameters

- `reader` (`Reader<TInput>`)
- `field` (`Field`)

```csharp
public void WriteField<TBufferWriter>(ref Writer<TBufferWriter> writer, uint fieldIdDelta, Type expectedType, object value)
```

Writes a field using the provided untyped value. The type must still match the codec instance!

### Parameters

- `writer` (`Writer<TBufferWriter>`)
- `fieldIdDelta` (`uint`)
- `expectedType` (`Type`)
- `value` (`object`)
