WinForm环境下，添加背景音乐

[sjbird331]

请问在WinForm环境下，如何添加背景音乐？有人说用wmp控件，可是我添加了com引用，又重新生成解决方案以后，依然没有找到这个wmp控件，请问这是怎么回事？

[jrl5365]

1：使用控件Microsoft MutileMedia Control Version 6.0,可在Vs.net中添加此控件.
取名为player.
'播放背景音乐
player.FileName = Application.StartupPath "\Music\GameMain.mid"
player.Command = "Open"
player.Command = "Play"
这种方法我测试过就可以播放wma和wmv格式的音乐文件，而且在播放wmv的时候会新建窗口


2.你可以用 directx 9 的托管DirectX.AudioVideoPlayback.DLL里面有个类命，你可以在C：的Microsoft.net的文件夹里面找到这个文件，用这个类Audio,用来播放音

乐很方便，
Audio v=Audio(".mp3");
v.ending +=new .....//添加事件处理函数！

在他的事件处理函数里可以写
v.open("声音文件名！")
v.play();
详细的可以自己处理一下就行了！

请教:为什么我的程序在调试的时候能播放音乐,但是生成安装文件后运行却播放不了了,楼上的大侠发扬一下侠客精神.三颗药!
