Public ReadOnly Property Description As StylusPointDescription
Waarde van eigenschap
De StylusPointDescription die is gekoppeld aan de StylusPoint objecten in de StylusPointCollection.
Voorbeelden
In het volgende voorbeeld wordt de StylusPointDescription for a StylusPointCollection opgehaald en worden de gegevens voor elk StylusPointPropertyInfo in de StylusPointDescription.
private void WriteDescriptionInfo(StylusPointCollection points)

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());
descriptionStringWriter.WriteLine(" Guid = {0}", property.Id.ToString());
descriptionStringWriter.Write(" IsButton = {0}", property.IsButton.ToString());
