## Remarks

A resource database owns an [AssetProvider](/engine/6000.7/script-reference/unity/localization/providers/assetprovider.md) chain and an internal per-locale asset cache. Access the active database through [LocalizationSettings.Database](/engine/6000.7/script-reference/unity/localization/localizationsettings/database.md). Tables load through the provider chain like any other asset (the database keeps no table list), so use the reference types [TableReference](/engine/6000.7/script-reference/unity/localization/tablereference.md) and [TableEntryReference](/engine/6000.7/script-reference/unity/localization/tableentryreference.md) to identify what to resolve. String entries flagged as Smart are formatted through the settings' Smart formatter (see [LocalizationSettings.GetSmartFormatter](/engine/6000.7/script-reference/unity/localization/localizationsettings/getsmartformatter.md)), and resolved values pass through the locale's post-processing hook, which pseudo-locales use to transform text. Each resolve method has an asynchronous form that loads on demand and a synchronous form that reads only already-loaded tables. Missing or empty entries follow the locale fallback chain defined by [Locale.FallbackCode](/engine/6000.7/script-reference/unity/localization/locale/fallbackcode.md).

Resolves a localized string in the selected locale.

## Examples

```csharp
using Unity.Localization;
using UnityEngine;

namespace Unity.Localization.Samples
{
    public class ResolveLocalizedStringExample : MonoBehaviour
    {
        async void Start()
        {
            ResourceDatabase database = LocalizationSettings.ResourceDatabase;
            string text = await database.GetLocalizedStringAsync("UI Text", "hello");
            Debug.Log(text);
        }
    }
}
```
