我在WPF窗口中有一個Frame元素,並且使用Frame.Navigate()加載了我的應用程序中的所有內容。但是,在導航到新頁面時,會默認播放該聲音,這與在Internet Explorer中播放的聲音相同。有什麼辦法可以從應用程序中轉換此聲音嗎?我不想在操作系統級別的控制面板中關閉設置。 謝謝。關閉WPF框架控件中的導航頁面聲音

編輯:我想唯一的辦法是改變操作系統級別的聲音,這可以在註冊表中完成。這對我來說是可接受的解決方案

似乎沒有其他的方式,只是在Windows設置中關閉等記載here

丹尼斯這裏 How to disable click sound in WebBrowser Control但對我來說沒有工作指出了一個解決方案。所以我修改了代碼,如下現在所有工作正常:

使用

注意命名的類的添加SafeNativeMethods
