Office 2013 的 UI 自动化

Question

我需要在 Office 2013 中自动按文件->信息->“检查问题”。 我设法用代码按下文件按钮：

AutomationElement window = AutomationElement.FromHandle(Window.Handle);
AutomationElementCollection buttons = window.FindAll(TreeScope.Descendants, new PropertyCondition(
AutomationElement.ControlTypeProperty, ControlType.Button));
AutomationElement file=buttons.Cast<AutomationElement>().FirstOrDefault(x => x.Current.Name == "File Tab");
InvokePattern ipClickLoadSettings = (InvokePattern)file.GetCurrentPattern(InvokePattern.Pattern);
ipClickLoadSettings.Invoke();

如何按“检查问题”按钮或信息窗口中的任何其他按钮？

谢谢

我使用 Inspect SDK 工具查看了 Word 2013 UI，这表明一些相关的 UI 可以通过 UIA Invoke 模式以编程方式调用，但有些则不能。相反，需要选择或扩展其他 UI。所以我只是写了下面的测试代码来做下面的……

1. 调用文件选项卡。
2. 选择信息项。
3. 扩展检查问题 UI。
4. 调用检查辅助功能按钮。

虽然代码做了一些假设（并且仅适用于 Word 的英文版本），但它似乎能够调用 Check Accessibility UI ok。

在我的测试中，我使用了 Windows 附带的非托管 UIA API，而不是托管的 .NET UIA API。我使用使用 tlbimp.exe 工具生成的包装器从 C# 代码调用 Windows UIA API。

这就是我为生成包装器所做的...

"C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6 Tools\x64\tlbimp.exe" c:\windows\System32\UIAutomationCore.dll /out:Interop.UIAutomationCore .dll

如果以下步骤对您不起作用，请告诉我，我可以调查一下。

谢谢，
