看看这个了

using System;
using System.Runtime.InteropServices;

class musicplay{
[DllImport("winmm.dll")]
private static extern long mciSendString(string lpstrCommand,string lpstrReturnString,long length,long hwndcallback);
public musicplay(string name){
filename=name;
}
public void play(){
t=mciSendString(@"open " + filename,m,0,0);
t=mciSendString(@"play " + filename + @" wait",m,0,0);
t=mciSendString(@"close " + filename,m,0,0);
}
private string filename;
private string m=@" ";
private long t;
}

class test{
static void Main(){
Console.WriteLine("请输入你要播放的歌曲的路径");
musicplay mpl=new musicplay(Console.ReadLine());
mpl.play();
Console.WriteLine("播放完毕,再见");

}
}

最简单的方法就是直接把媒体播放器的控件拖到窗体上来,

direct90sdk中有实例，从微软下吧
