Ejemplos

En el ejemplo siguiente se obtiene la StylusPointDescription para un StylusPointCollection y se obtiene la información de cada StylusPointPropertyInfo de StylusPointDescription .The following example gets the StylusPointDescription for a StylusPointCollection and gets the information for each StylusPointPropertyInfo in the StylusPointDescription.

private void WriteDescriptionInfo(StylusPointCollection points)
{
    StylusPointDescription pointsDescription = points.Description;
    ReadOnlyCollection<StylusPointPropertyInfo> properties = 
        pointsDescription.GetStylusPointProperties();

    StringWriter descriptionStringWriter = new StringWriter();
    descriptionStringWriter.Write("Property Count:{0}", pointsDescription.PropertyCount.ToString());
    
    foreach (StylusPointPropertyInfo property in properties)
    {
        // GetStylusPointPropertyName is defined below and returns the
        // name of the property.
        descriptionStringWriter.Write("name = {0}", GetStylusPointPropertyName(property).ToString());

Comentarios

Un StylusPointDescription especifica qué propiedades están asociadas a un StylusPoint .A StylusPointDescription specifies which properties are associated with a StylusPoint. Para cada propiedad de una StylusPoint , StylusPointDescription contiene un StylusPointPropertyInfo objeto que especifica restricciones como los valores mínimo y máximo de la propiedad.For each property in a StylusPoint, the StylusPointDescription contains a StylusPointPropertyInfo object which specifies constraints such as the minimum and maximum values of the property. Utilice los HasProperty GetPropertyInfo métodos y para comprobar estas propiedades en StylusPointDescription .Use the HasProperty and GetPropertyInfo methods to check for these properties in the StylusPointDescription.

Todos los StylusPoint objetos de un StylusPointCollection deben compartir el mismo StylusPointDescription .All StylusPoint objects in a StylusPointCollection must share the same StylusPointDescription. Si intenta agregar un StylusPoint a un StylusPointCollection que tiene un diferente, se StylusPointDescription iniciará una excepción.If you try to add a StylusPoint to a StylusPointCollection that has a different StylusPointDescription, an exception will be thrown.
