An instance of the FieldAdapterCollection class contains adapters for all application fields of the page it belongs to. An instance of this class can be obtained via the `DocumentController.Page.FieldAdapters` property. The FieldAdapterCollection that can be accessed via the `DocumentController.FieldAdapters` property contains adapters for all the application fields in the currently loaded document, of course. The FieldAdapterCollection class implements the IEnumerable and the ICollection interfaces and is part of the `TXTextControl.DocumentServer.DocumentController` namespace.

public sealed class DocumentController.FieldAdapterCollection : ICollection, IEnumerable
```

```vbnet
Public NotInheritable Class DocumentController.FieldAdapterCollection
    Implements ICollection, IEnumerable
```

### Examples

The following example creates a Field Adapter Collection instance for a document-processing operation. The created object is then available to the surrounding document workflow.

```csharp
TXTextControl.DocumentServer.DocumentController.FieldAdapterCollection fieldAdapterCollection = new(new UserDefinedPropertyDictionary(), new ServerTextControl());
Console.WriteLine("Field Adapter Collection is ready for use.");
```

```vbnet
Dim fieldAdapterCollection As New TXTextControl.DocumentServer.DocumentController.FieldAdapterCollection(New UserDefinedPropertyDictionary(), New ServerTextControl())
Console.WriteLine("Field Adapter Collection is ready for use.")
