When declaring a `ShouldSerialize` or `Reset` method, use the `private` access modifier. These methods are usually invoked by the designer and not by user code.
The `Reset`*PropertyName* method sets a property to its default value, as shown in the following code fragment.
```vb
Public Sub ResetMyFont()
Private Sub ResetMyFont()
MyFont = Nothing
End Sub
```
```csharp
public void ResetMyFont() {
private void ResetMyFont()
{
MyFont = null;
}
```
