Ejemplos

En el ejemplo de código siguiente se muestra cómo escribir básica IHierarchyData propiedades para un HttpResponse transmitir, a continuación, comprobar el tipo de un IHierarchyData objeto utilizando el Type propiedad y el objeto para realizar más operaciones específicas del tipo de conversión.The following code example demonstrates how to write the basic IHierarchyData properties to an HttpResponse stream, then check the type of an IHierarchyData object using the Type property and cast the object to perform more type-specific operations. Este ejemplo de código forma parte de un ejemplo más extenso proporcionado para el IHierarchyData interfaz.This code example is part of a larger example provided for the IHierarchyData interface.

// children and do the same.

    // Check for specific types and perform extended functions.
    if (node.Type == "SiteMapNode")
    {
        // Because SiteMapNode implements the IHierarchyData interface,
        // the IHierarchyData object can be cast directly as a SiteMapNode,
        // rather than accessing the Item property for the object that
        // the Type property identifies.
        SiteMapNode siteNode = node.Item as SiteMapNode;
        Response.Write(whitespace + siteNode.Url + br);

        // object of some kind, you can retrieve the business object by using
        // the IHierarchyData.Item property.

Comentarios

El Type propiedad no devuelve el System.Type del objeto representado en un IHierarchyData objeto.The Type property does not return the System.Type of the object represented in an IHierarchyData object. Devuelve un nombre utilizado por los controles enlazados a datos para diferenciar entre los elementos de una jerarquía que tienen diferentes propiedades enlazables.It returns a name used by data-bound controls to differentiate between items in a hierarchy that have different bindable properties.
