在c＃

Question

我目前通过分别实施IRawElementProviderFragmentRoot和IRawElementProviderFragment向窗格控件和子控件添加UIA支持。

UIA片段使用方法public object GetPropertyValue(int propertyId)将特定属性返回到Ranorex或Test Complete等测试记录器。例如：

/// <summary>
/// Retrieves the value of a property supported by the UI Automation provider.
/// </summary>
/// <param name="propertyId"></param>
/// <returns></returns>
public object GetPropertyValue(int propertyId)
{
    if (propertyId == AutomationElementIdentifiers.NameProperty.Id)
    {
        // Name of this control. Since this is a top level pane, we'll use the partition name
        return View.Document.FullName;
    }
    else if (propertyId == AutomationElementIdentifiers.ControlTypeProperty.Id)
    {
        // Pane controls represent a level of grouping lower than windows or documents, but above individual controls.
        // The user can navigate between panes and within contents of the current pane, but cannot navigate between items in 
        // different panes. The pane navigation shortcut is typically CTRL + TAB.
        return ControlType.Pane.Id;
    }
    else if (propertyId == AutomationElementIdentifiers.IsContentElementProperty.Id)
    {
        // Indicates whether the element contains content that is valuable to the end user
        return true;
    }
    else if (propertyId == AutomationElementIdentifiers.IsControlElementProperty.Id)
    {
        // Indicates whether the element is viewed as a control
        return true;
    }
    else if (propertyId == AutomationElementIdentifiers.IsKeyboardFocusableProperty.Id)
    {
        // You can't explicitly focus a tab, the whole window gets focused
        return false;
    }
    else
    {
        // Null indicates no support
        return null;
    }
}

我希望注册一个自定义属性并在上面的方法中处理Get调用。根据此MSDN article，您的自定义属性可以返回

1. UIAutomationType_Bool
2. UIAutomationType_Double
3. UIAutomationType_Element
4. UIAutomationType_Int
5. UIAutomationType_Point
6. UIAutomationType_String

这正是我想要的。不幸的是，这些指令都是用C ++编写的，而且似乎并不是一个相应的C＃程序集来完成这一切。我是否必须执行一些托管 - >非托管编组才能实现此目的？我该怎么做呢？

提前致谢！
