我正在尝试使用C＃.net ui-automation和winapi
读取另一个进程的SysListView32中的数据网格项使用ui-automation的C＃代码
http://pastebin.com/6x7rXMiW
使用winapi的C＃代码 http://pastebin.com/61RjXZuK
使用此代码，您只需将鼠标指针放在屏幕上的SysListView32上，然后按Enter键。
现在两个代码在具有以下属性
的单元格项上返回空pastebin.com/Rw9FGkYC
但两个代码都适用于以下属性
pastebin.com/L51T4PLu
唯一的区别我注意到name属性包含与单元格中相同的数据，但是当name属性为空时会出现问题。
还有其他方法可以阅读细胞吗？或者我可以做出任何改变，请详细说明。
答案 0 :(得分：3)
我还建议使用Inspect工具。如果你看到这个：
IsLegacyIAccessiblePatternAvailable: true
您可以使用LegacyIAccessiblePattern。其他帖子似乎表明它尚未在客户端UI自动化Api中，但它在核心。您可以通过包装它来使用.NET中的核心。我将其添加到我的构建中以开始使用它：
"%PROGRAMFILES%\Microsoft SDKs\Windows\v7.0A\bin\tlbimp.exe" %windir%\system32\UIAutomationCore.dll /out:..\interop.UIAutomationCore.dll"
如果确实支持这种模式，我可以添加更多细节。
那么，你可能很好。
以下是一些示例代码：
