Ejemplos

En el ejemplo siguiente se llama GetNeverSupportedPatterns a en cada tipo de ControlType contenido como un campo estático de la ControlType clase .

/// <summary>
/// Obtains information about patterns supported by control types.
/// Control types are obtained by reflection.
/// </summary>
private void ListPatterns()
{
    // Any instance of a ControlType will do since we just want to get the type.
    ControlType controlTypeInstance = ControlType.Button;
    Type type = typeof(ControlType);
    System.Reflection.FieldInfo[] fields = type.GetFields();
    foreach (System.Reflection.FieldInfo field in fields)
    {
        if (field.IsStatic)
        {
            ControlType controlType = field.GetValue(controlTypeInstance) as ControlType;
            Console.WriteLine("\n******************** {0} never supports:",
                               controlType.ProgrammaticName);
            AutomationPattern[] neverSupportedPatterns =
                               controlType.GetNeverSupportedPatterns();
            if (neverSupportedPatterns.Length == 0)
            {
                Console.WriteLine("(None)");
