UI Automation－TransformPattern
表示一个可以在二维空间中移动，调整大小或旋转的控件。TransformPattern控件的主要方法有Move（移动控件），resize（调整控件大小）和rotate（旋转控件）。
示例：
public static void TestTransformPattern()
{
Process adressbook = Process.Start(@"C:/Program Files/Outlook Express/wab.exe");
Thread.Sleep(2000);
//Get main window "Address Book - Main Identity"
AutomationElement addresswindow = AutomationElement.RootElement.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Address Book - Main Identity"));
Thread.Sleep(2000);
TransformPattern windowpattern = Utility.UIA.ControlPattern.Transformpattern.GetTransformPattern(addresswindow);
windowpattern.Move(10, 0);
Thread.Sleep(1000);
windowpattern.Resize(200, 200);
Thread.Sleep(2000);
if (windowpattern.Current.CanRotate.ToString() == "True")
windowpattern.Rotate(20);
Thread.Sleep(1000);
}
public static TransformPattern GetTransformPattern(
AutomationElement targetControl)
{
TransformPattern transformPattern = null;
try
