從.net代碼更改音量

Question

是否有一種簡單的方法來設置來自託管.NET代碼的音量？

Answer 1

這個相當長的介紹瞭如何：Controlling sound volume in C#

Answer 2

This CodeProject article演示如何完全控制Windows混音設置，包括主音量的系統。它似乎包裝了大部分可怕的Win API，所以它可能是最簡單的方法。

Answer 3

簡單的答案：你必須使用互操作。

Answer 4

這會爲我的Windows 7：

下載n音訊（HTTP： //naudio.codeplex.com/releases/view/79035）並在您的項目中引用該DLL。比添加以下代碼：

 try 
     { 
      //Instantiate an Enumerator to find audio devices 
      NAudio.CoreAudioApi.MMDeviceEnumerator MMDE = new NAudio.CoreAudioApi.MMDeviceEnumerator(); 
      //Get all the devices, no matter what condition or status 
      NAudio.CoreAudioApi.MMDeviceCollection DevCol = MMDE.EnumerateAudioEndPoints(NAudio.CoreAudioApi.DataFlow.All, NAudio.CoreAudioApi.DeviceState.All); 
      //Loop through all devices 
      foreach (NAudio.CoreAudioApi.MMDevice dev in DevCol) 
      { 
       try 
       { 
        //Set at maximum volume 
        dev.AudioEndpointVolume.MasterVolumeLevel = 0; 

        //Get its audio volume 
        System.Diagnostics.Debug.Print("Volume of " + dev.FriendlyName + " is " + dev.AudioEndpointVolume.MasterVolumeLevel.ToString()); 

        //Mute it 
        dev.AudioEndpointVolume.Mute = true; 
        System.Diagnostics.Debug.Print(dev.FriendlyName + " is muted"); 
       } 
       catch (Exception ex) 
       { 
        //Do something with exception when an audio endpoint could not be muted 
        System.Diagnostics.Debug.Print(dev.FriendlyName + " could not be muted"); 
       } 
      } 
     } 
     catch (Exception ex) 
     { 
      //When something happend that prevent us to iterate through the devices 
      System.Diagnostics.Debug.Print("Could not enumerate devices due to an excepion: " + ex.Message); 
     }
