Exempel
I följande exempel anropas GetNeverSupportedPatterns alla typer av ControlType innehåll som ett statiskt fält i ControlType klassen.
/// <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)");
}
else
{
foreach (AutomationPattern pattern in neverSupportedPatterns)
{
Console.WriteLine(pattern.ProgrammaticName);
}
}
Console.WriteLine("\n******************** {0} requires:",
controlType.ProgrammaticName);
AutomationPattern[][] requiredPatternSets =
controlType.GetRequiredPatternSets();
if (requiredPatternSets.Length == 0)
{
Console.WriteLine("(None)");
}

foreach (AutomationPattern[] patterns in requiredPatternSets)
{
Console.WriteLine("Pattern set:");
foreach (AutomationPattern pattern in patterns)
{
Console.WriteLine(pattern.ProgrammaticName);
}
Console.WriteLine("--------------------");

Kommentarer
Den här metoden är användbar för UI Automation klienter, till exempel testramverk för en providerimplementering som behöver hitta alla kontrollmönster som inte är tillåtna för den här kontrolltypen.
