c#在webform中如何播放声音文件

Question

如何实现c#在webform中播放声音?我建立的是web窗体，无法引用winmm.dll，好像是因为这种方法只用于windows应用程序的；大家最好能给出代码。谢谢

Answer 1

[DllImport("winmm.dll")]   
  public   static   extern   long PlaySound(String   fileName,long   a,long   b);   
  然后在程序里调用它FILENAME文件。   
  PlaySound("路径\am.wav",0,0);   
  名字空间不要忘记：   
  using   System.Runtime.InteropServices;
