将DWORD事件常量从WinEventProc转换为c#中的名称

本文关键字：转换 事件 DWORD 常量 WinEventProc | 更新日期: 2023-09-27 18:08:32

我使用SetWinEventHook和WinEventProc捕获窗口消息

在WinEventProc中有一个参数"DWORD event"，带有一个数字来表示事件

我想把这个数字转换成一个名字

是否有一个c#函数来做到这一点?

我的代码是基于这里的答案在Windows消息上设置Hook

这可能有点痛苦，但是您可以尝试创建一个T4模板来挖掘平台sdk C头文件，解析值，并为您创建枚举。如果您这样做，那么如果您获得具有新值的平台SDK更新，它们将自动包含到您的enum中(假设您再次生成T4输出)。
