[C#] 見えている全ウインドウのハンドルを取得

Posted at

別記事で、ウインドウのハンドルを全部取ってきて、それを使ってウインドウを全部最小化、とかをしたが、その「ウインドウのハンドルを全部取ってくる」方法の別解があったのでメモ。

見えてるウインドウ全部取得 サンプルコード

        public static void aaa()
        {
            var top = NativeMethods.GetTopWindow(IntPtr.Zero);

            DispHwndTitle(top);

            IntPtr w = NativeMethods.GetWindow(top, NativeMethods.GetWindowType.GW_HWNDNEXT);
            while (w != IntPtr.Zero)
            {
                    DispHwndTitle(w);

                w = NativeMethods.GetWindow(w, NativeMethods.GetWindowType.GW_HWNDNEXT);
            }

            void DispHwndTitle(IntPtr w)
            {

                if (NativeMethods.IsWindowVisible(w) == true)
                {
                    int textLen = NativeMethods.GetWindowTextLength(w);

                    if (textLen > 0)
                    {
                        StringBuilder tsb = new StringBuilder(textLen + 1);
                        NativeMethods.GetWindowText(w, tsb, tsb.Capacity);
                        StringBuilder csb = new StringBuilder(256);
                        NativeMethods.GetClassName(w, csb, csb.Capacity);

                        if (!(csb.ToString().Contains("Windows.UI.Core.CoreWindow"))
                            && !(csb.ToString().Contains("ApplicationFrameWindow")))
                        {
                            // デスクトップアプリのウインドウ
                            Debug.WriteLine("desk : " + tsb.ToString());
                        }
                        else if (csb.ToString().Contains("ApplicationFrameWindow"))
                        {
                            // UWPのウインドウ
                            Debug.WriteLine("uwp  : " + tsb.ToString());
                        }
                    }
                }

            }
        }
