# RestoreDefault()

> Restores the built-in pluralization rule for every language.

## Definition

* **Type:** Method
* **Namespace:** [Unity.SmartStrings.Utilities](/engine/7000.0/script-reference/unity/smartstrings/utilities.md)
* **Assembly:** UnityEngine.SmartStringsModule

```csharp
public static void RestoreDefault()
```

### Remarks

Refills [PluralRules.IsoLangToDelegate](/engine/7000.0/script-reference/unity/smartstrings/utilities/pluralrules/isolangtodelegate.md) with only the built-in rules, which discards every rule you added or replaced. A change to [PluralRules.IsoLangToDelegate](/engine/7000.0/script-reference/unity/smartstrings/utilities/pluralrules/isolangtodelegate.md) applies to all formatting in the project, so call this method once you no longer need your custom rules, for example at the end of a test that registers one.

### Examples

```csharp
using System.Globalization;
using Unity.SmartStrings;
using Unity.SmartStrings.Utilities;
using UnityEngine;

public static class CustomPluralRuleExample
{
    public static void FormatWithCustomRule()
    {
        var english = CultureInfo.GetCultureInfo("en");

        // Use the first plural word for every count while the custom rule is registered.
        PluralRules.IsoLangToDelegate["en"] = (value, pluralWordsCount) => 0;

        try
        {
            Debug.Log(Smart.Format(english, "{0} {0:plural:item|items}", 5)); // 5 item
        }
        finally
        {
            PluralRules.RestoreDefault();
        }

        Debug.Log(Smart.Format(english, "{0} {0:plural:item|items}", 5)); // 5 items
    }
