# ExpandSubstitutions(string,IList\<string>)

Method in [LineParser](/3.1/api/csharp/yarn.markup/yarn.markup.lineparser.md)

## Summary

Replaces all substitution markers in a text with the given substitution list.

```csharp
public static string ExpandSubstitutions(string text, IList<string> substitutions)
```

## Remarks

This method replaces substitution markers - for example, `{0}`

* with the corresponding entry in `substitutions` . If `text` contains a substitution marker whose index is not present in `substitutions` , it is ignored.

| `string` text                                            | The text containing substitution markers. |
| `System.Collections.Generic.IList<string>` substitutions | The list of substitutions.                |
