Public Property XmlRoot As XmlRootAttribute

Valor de propiedad

XmlRootAttribute que reemplaza una clase con atributos de elemento raíz XML.

Ejemplos

En el ejemplo siguiente se crea un XmlAttributeOverrides objeto, un XmlAttributes objeto y un XmlRootAttribute objeto . En el ejemplo se asigna a XmlRootAttribute la XmlRoot propiedad del XmlAttributes objeto y se agrega el XmlAttributes objeto al XmlAttributeOverrides objeto . Por último, el ejemplo obtiene el XmlAttributes objeto pasando la Type clase serializada al XmlAttributeOverrides objeto . (En este ejemplo, Type es Group).
