如何找出最上面是什么表格？

在 Compact Framework 中，如何找出向用户显示的表单（即使它不是全屏）？

有什么想法吗？如果我找到答案，我会继续寻找并回复（但没有人回复）。

Answer 1

示例来自 http://www.pinvoke.net/default.aspx/user32/GetForegroundWindow .html：

public ApplicationState AppState
{
    get
    {
        Process[] processCollection = Process.GetProcessesByName(ProcessName);
        if(processCollection != null && processCollection.Length  >= 1 && 
            processCollection[0] != null)
        {
            IntPtr activeWindowHandle = Win32.GetForegroundWindow();
            //Optional int ProcessID;
            //Optional Win32.GetWindowThreadProcessId(GetForegroundWindow(),out ProcessID)
            foreach(Process wordProcess in processCollection)
            {
                //Optional if( ProcessID == wordProcess.Id ) return ApplicationState.Focused;
                if(wordProcess.MainWindowHandle == activeWindowHandle)
                {
                    return ApplicationState.Focused;
                }
            }
            return ApplicationState.Running;
        }
        return ApplicationState.NotRunning;
    }
}

看起来您可以 p/invoke GetForegroundWindow 来查找当前窗口。
