如何判断是否主音量静音？ [英] How do I tell if the master volume is muted?

问题描述

我用下面的静音/取消静音我的电脑上的主音频。现在，我正在寻找一种方法来确定的静音状态。是否有一个同样简单的方式在C＃中做到这一点。

 私人const int的APPCOMMAND_VOLUME_MUTE = 0x80000？; 
私人const int的WM_APPCOMMAND = 0x319; 
函数[DllImport（user32.dll中）] 
公共静态外部的IntPtr SendMessageW（IntPtr的的HWND，诠释消息，IntPtr的的wParam，lParam的IntPtr的）; 
  

解决方案

感谢RRUZ在上述评论。见stackoverflow.com/questions/294292。唯一的问题是，你需要兼容模式。

I am using the following to mute/unmute the master audio on my computer. Now, I am looking for a way to determine the mute state. Is there a just as easy way to do this in C#?

    private const int APPCOMMAND_VOLUME_MUTE = 0x80000;
    private const int WM_APPCOMMAND = 0x319;
    [DllImport("user32.dll")]
    public static extern IntPtr SendMessageW(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);

解决方案

Credit to RRUZ in comments above. See stackoverflow.com/questions/294292. The only problem is that you need compatibility mode.
