Contoh

Contoh berikut membuat StylusPointDescription objek dari StylusPointCollection dan mendapatkan informasi untuk masing-masing StylusPointPropertyInfo di 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());
    }

    descriptionOutput.Text = descriptionStringWriter.ToString();
}

    Dim pointsDescription As StylusPointDescription = points.Description

    Dim properties As ReadOnlyCollection(Of StylusPointPropertyInfo) = _

        ' name of the property.
        descriptionStringWriter.Write("name = {0}", GetStylusPointPropertyName(pointProperty).ToString())
        descriptionStringWriter.WriteLine("  Guid = {0}", pointProperty.Id.ToString())
        descriptionStringWriter.Write("  IsButton = {0}", pointProperty.IsButton.ToString())

    Next pointProperty

    descriptionOutput.Text = descriptionStringWriter.ToString()

End Sub
// Use reflection to get the name of currentProperty.

{
    Guid guid = currentProperty.Id;

    // Iterate through the StylusPointProperties to find the StylusPointProperty
    // that matches currentProperty, then return the name.
    foreach (FieldInfo theFieldInfo
        in typeof(StylusPointProperties).GetFields())
    {
        StylusPointProperty property = (StylusPointProperty) theFieldInfo.GetValue(currentProperty);
        if (property.Id == guid)
        {
            return theFieldInfo.Name;
        }
    }
    return "Not found";
}

Private Function GetStylusPointPropertyName(ByVal currentProperty As StylusPointProperty) As String 
    Dim guid As Guid = currentProperty.Id

    ' that matches currentProperty, then return the name.
    Dim theFieldInfo As FieldInfo

    For Each theFieldInfo In GetType(StylusPointProperties).GetFields()

        Dim pointProperty As StylusPointProperty = _

        If pointProperty.Id = guid Then
            Return theFieldInfo.Name
        End If

    Next theFieldInfo

    Return "Not found"

End Function 'GetStylusPointPropertyName
