显示当前的卷状态 [英] Show current volume status

问题描述

我需要显示计算机的音量状态。

我创建了两张图片来显示音量是否静音。

我发现这段代码但是我得到错误：

I need to show the volume status of the computer.
I created two pictures to show if the volume is muted or not.
I found this code but I get errors:

MMDeviceEnumerator devEnum = new MMDeviceEnumerator();
MMDevice defaultDevice = devEnum.GetDefaultAudioEndpoint(EDataFlow.eRender, ERole.eMultimedia);
defaultDevice.AudioEndpointVolume.Mute = true;

所以这里我会说一个条件说如果它是真的显示静音图片等等

但它不承认

像[这里]



我的尝试：



我尝试了这段代码，但它显示了一些错误。

我在一些论坛上看到我必须把这个：

使用CoreAudioApi;

但它也显示错误。

So here I will put a condition to say that if it is true show the mute picture and so on
but it doesn't recognize
like [here]

What I have tried:

I tried this code but it shows some errors.
I saw in some forums that I must put this:
using CoreAudioApi;
But also it shows errors.

推荐答案

您是否已将 CoreAudioAPI.dll 下载到您的磁盘呢？

如果是这样，那么你必须在项目中引用CoreAudioAPI.dll。

转到你的项目属性 - 参考 - 添加 - 浏览 - 本地化DLL。



在您的表格上添加导入声明

Have you downloaded the CoreAudioAPI.dll to your disk yet?
If so then you must make a reference to the CoreAudioAPI.dll on your project.
Go to your Project Properties - References - Add - Browse - Localize the DLL.

On your Form, add an import statement

using CoreAudioAPI;

我在不久前用R.Molenkamp编写的CoreAudioAPI帮助在VB.NET中创建了一个VUMeter应用程序。

请注意，Windows XP不支持CoreAudioAPI。

如果是帮助，请接受此解决方案并投票，谢谢。

I have created some time ago a VUMeter application in VB.NET with the help of CoreAudioAPI which is written by R.Molenkamp.

Be aware that CoreAudioAPI is not supported on Windows XP.
