## Remarks

Aspose.Words represents a Word document as a tree of nodes. `DocumentBase` is a root node of the tree that contains all other nodes of the document.

`DocumentBase` also stores document-wide information such as [`Styles`](./styles/) and [`Lists`](./lists/) that the tree nodes might refer to.

## Examples

Shows how to initialize the subclasses of DocumentBase.

```csharp
Document doc = new Document();

Assert.That(doc.GetType().BaseType, Is.EqualTo(typeof(DocumentBase)));

GlossaryDocument glossaryDoc = new GlossaryDocument();
doc.GlossaryDocument = glossaryDoc;

Assert.That(glossaryDoc.GetType().BaseType, Is.EqualTo(typeof(DocumentBase)));
```
