示例

下面的示例StylusPointCollection从创建StylusPointDescription一个对象, 并获取中每个StylusPointPropertyInfoStylusPointDescription信息。The following example creates an StylusPointDescription object from 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());
        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());
