最近在做一个监控项目的时候要求在监控的时候可以采用声音告警，如果用的是VS那么直接调用Media player好了，可惜自己用的是#Develop做为开发环境。居然不支持com组件的引用。我倒~于是参照MS API写了下面这个简单的播放类
/* * Created by SharpDevelop. * User: root * Date: 2006-8-16 * Time: 15:44 * * To change this template use Tools | Options | Coding | Edit Standard Headers. */
using System;using System.Runtime.InteropServices;
namespace Com.Music{ /// <summary> /// 音乐播放类 /// 参考：http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/_win32_multimedia_command_strings.asp /// </summary> public class MusicPlayer { [DllImport("winmm.dll")] private static extern long mciSendString(string strCommand, string strReturn, int iReturnLength, IntPtr hwndCallback); public MusicPlayer() { } //播放器状态 /* * * All devices can return the * "not ready", "paused", "playing", and "stopped" values. * Some devices can return the additional * "open", "parked", "recording", and "seeking" values * */ public string Status { get{ string sCommand = "status MediaFile mode"; string ret=""; mciSendString(sCommand, ret, 10, IntPtr.Zero); return ret.Trim(); } } private void Open(string sFileName) { string sCommand="open /"" + sFileName + "/" type mpegvideo alias MediaFile"; // MediaFile是选择播放文件类型 string ret=null; mciSendString(sCommand, ret, 0, IntPtr.Zero); } //播放音乐 public void Play(string filename) { Open(filename); string sCommand = "play MediaFile"; string ret=null; mciSendString(sCommand,ret, 0, IntPtr.Zero); } //停止播放音乐 public void Stop() { string sCommand = "stop MediaFile"; string ret=null; mciSendString(sCommand, ret, 0, IntPtr.Zero); } public void Pause() { string sCommand = "pause MediaFile"; string ret=null; mciSendString(sCommand, ret, 0, IntPtr.Zero); } }}
播放的话只要一句就搞定MusicPlayer mp = new MusicPlayer();void Button1Click(object sender, System.EventArgs e) { mp.Play("H:/mp3/十七岁的雨季.mp3"); }另外拿这个测试拉下MONO 1.6 beta 还不错开来MONO也开始支持调用OS本地API了。
