Contoh
Contoh berikut mendapatkan StylusPointDescription untuk StylusPointCollection dan mendapatkan informasi untuk masing-masing StylusPointPropertyInfo di StylusPointDescription.
private void WriteDescriptionInfo(StylusPointCollection points)

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());
descriptionStringWriter.WriteLine(" Guid = {0}", property.Id.ToString());
descriptionStringWriter.Write(" IsButton = {0}", property.IsButton.ToString());
descriptionStringWriter.Write(" Min = {0}", property.Minimum.ToString());
descriptionStringWriter.Write(" Max = {0}", property.Maximum.ToString());
descriptionStringWriter.Write(" Unit = {0}", property.Unit.ToString());
descriptionStringWriter.WriteLine(" Res {0}", property.Resolution.ToString());
}
descriptionOutput.Text = descriptionStringWriter.ToString();
