XmlAttributes.XmlText XmlAttributes.XmlText XmlAttributes.XmlText XmlAttributes.XmlText Property

Definición

Obtiene o establece un objeto que instruye al objeto XmlSerializer para que serialice un campo público o una propiedad pública de lectura/escritura como texto XML.Gets or sets an object that instructs the XmlSerializer to serialize a public field or public read/write property as XML text.

public:
 property System::Xml::Serialization::XmlTextAttribute ^ XmlText { System::Xml::Serialization::XmlTextAttribute ^ get(); void set(System::Xml::Serialization::XmlTextAttribute ^ value); };
public System.Xml.Serialization.XmlTextAttribute XmlText { get; set; }
member this.XmlText : System.Xml.Serialization.XmlTextAttribute with get, set
Public Property XmlText As XmlTextAttribute

Valor de propiedad

XmlTextAttribute que reemplaza la serialización predeterminada de un campo público o una propiedad pública.An XmlTextAttribute that overrides the default serialization of a public property or field.

Ejemplos

En el ejemplo siguiente se serializa la clase Groupdenominada, que contiene un campo Commentdenominado.The following example serializes the class named Group, which contains a field named Comment. Para reemplazar el modo XmlSerializer predeterminado en que serializa el campo, en el ejemplo se crea un XmlAttributes XmlAttributeOverrides objeto y un objeto.To override the default way the XmlSerializer serializes the field, the example creates an XmlAttributeOverrides and an XmlAttributes object. A continuación, en el XmlTextAttribute ejemplo se crea un objeto, que se asigna XmlText a la propiedad, y XmlAttributes se agrega el objeto (con el nombre del campo que se va a XmlAttributeOverrides serializar como texto XML) al objeto.The example then creates an XmlTextAttribute object, which it assigns to the XmlText property, and adds the XmlAttributes object (with the name of the field to be serialized as XML text) to the XmlAttributeOverrides object. Por último, en el ejemplo XmlSerializer se crea XmlAttributeOverrides con el objeto.Lastly the example creates an XmlSerializer using the XmlAttributeOverrides object.

Comentarios

De forma predeterminada, un campo público o una propiedad pública de lectura/escritura se serializa como un elemento XmlSerializerXML.By default, a public field or public read/write property is serialized as an XML element by the XmlSerializer. Sin embargo, puede forzar la serialización del campo o la propiedad como texto XML aplicando XmlTextAttribute un al campo o propiedad.However, it can force the field or property to be serialized as XML text by applying an XmlTextAttribute to the field or property.

Nota

XmlTextAttribute No se puede aplicar a un campo o propiedad que devuelva una matriz.The XmlTextAttribute cannot be applied to a field or property that returns an array.

Para invalidar la serialización predeterminada de un campo o una propiedad (que no devuelve una matriz), cree XmlTextAttribute un y asígnelo a la XmlText propiedad de un XmlAttributes objeto.To override the default serialization of a field or property (that does not return an array), create an XmlTextAttribute and assign it to the XmlText property of an XmlAttributes object. Agregue el XmlAttributes objeto a un XmlAttributeOverrides objeto y especifique el tipo del objeto que contiene el campo o la propiedad invalidados, así como el nombre del campo o propiedad invalidado.Add the XmlAttributes object to an XmlAttributeOverrides object and specify the type of the object that contains the overridden field or property, and the name of the overridden field or property.
