Comentários
Use o MergeWith método para combinar as propriedades de estilo do objeto especificado Style com as propriedades de estilo do TreeNodeStyle objeto do qual esse método é chamado.
Observação
O MergeWith método une as propriedades de estilo definindo cada propriedade que não está definida no objeto atual TreeNodeStyle com seu valor correspondente no objeto especificado Style . Somente as propriedades que não foram definidas são atualizadas. Se uma propriedade no objeto especificado Style não estiver definida, a propriedade correspondente no objeto atual TreeNodeStyle não será alterada.
