Utilice el CopyFrom método para duplicar las propiedades de estilo del objeto especificado Style en el TreeNodeStyle objeto que llama a este método.

Nota

Todas las propiedades del objeto actual TreeNodeStyle se reemplazan por las propiedades correspondientes del objeto especificado Style .

Para copiar propiedades de estilo sin reemplazar los valores que ya se han establecido, use el MergeWith método .
