UIAutomation学习

1. 在另一线程中执行Find等操作
   

   IntPtr handle = frm.Handle;
   
   Action act = () =>
   {
       UIAutomationMapping mapping = new UIAutomationMapping(handle);
   
       foreach (AutomationElement item in mapping.CheckedListBoxColumnNamesRows)
       {
           item.SetFocus();
           SendKeys.SendWait(" ");  // Send a {SPACE} to check the checkbox. 
       }
   
       InvokePattern aeOkButtonClick = (InvokePattern)mapping.ButtonOk.GetCurrentPattern(InvokePattern.Pattern);
       aeOkButtonClick.Invoke();
   };
   
   act.BeginInvoke(null, null);

2. 查找列表:
   this.CheckedListBoxColumnNames.FindAll(TreeScope.Descendants,
                       new PropertyCondition(
                           AutomationElement.ControlTypeProperty,
                           ControlType.ListItem));
3. TogglePattern似乎对CheckListBox不起作用, 可用如下代码代替:
   item.SetFocus();
   SendKeys.SendWait(" ");  // Send a {SPACE} to check the checkbox.
