An instance of this class can be obtained with the [HeaderFooter.PageNumberFields](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/headerfooter/pagenumberfields-property/llms-full.txt) property. The PageNumberFieldCollection class implements the IEnumerable and the ICollection interfaces. For more information see the technical article Text Fields and Hypertext Links.

### Syntax

```csharp
public sealed class PageNumberFieldCollection : TextFieldCollectionBase
```

```vbnet
Public NotInheritable Class PageNumberFieldCollection
    Inherits TextFieldCollectionBase
```

### Examples

The following example obtains a footer's page-number collection and builds a “Page X of Y” label.

```csharp
textControl.HeadersAndFooters.Add(HeaderFooterType.Footer);
HeaderFooter footer = textControl.HeadersAndFooters.GetItem(HeaderFooterType.Footer);
PageNumberFieldCollection fields = footer.PageNumberFields;
footer.Selection.Text = "Page ";
fields.Add(new PageNumberField());
footer.Selection.Text = " of ";
fields.Add(new PageNumberField() { ShowNumberOfPages = true });
```

```vbnet
textControl.HeadersAndFooters.Add(HeaderFooterType.Footer)
Dim footer As HeaderFooter = textControl.HeadersAndFooters.GetItem(HeaderFooterType.Footer)
Dim fields As PageNumberFieldCollection = footer.PageNumberFields
footer.Selection.Text = "Page "
fields.Add(New PageNumberField())
footer.Selection.Text = " of "
fields.Add(New PageNumberField() With { .ShowNumberOfPages = True })
```
