下面通过图文并茂的方式给大家分享C#实现KTV点歌系统。

public enum SongPlayState { //未播放，播放，重播，切歌 unplayed, played, again, cut } public class Song { public string SongName { get; set; }//歌曲名称 public string SongURL { get; set; }//歌曲路径 public SongPlayState playState = SongPlayState.unplayed;//默认未播放 internal SongPlayState PlayState { get; set; } //状态为已播 public void SetSongPlayed() { this.PlayState = SongPlayState.played; } //重唱 public void SetPlayAgain() { this.playState = SongPlayState.again; } //切歌 public void SetSongCut() { this.playState = SongPlayState.cut; }

PlayList类中实现切歌 重唱 下一首 等.....

public class PlayList { //定义一个长度为、 的歌曲数组，默认存储 首歌曲 public static Song[] SongList = new Song[ ]; public static int SongIndex = ;//当前播放的歌曲在数组中的索引 //点播一首歌曲，其实是将歌曲对象添加到歌曲数组中 public static bool AddSong(Song song) { bool success = false;//记录添加歌曲是否成功 for (int i = ; i < SongList.Length; i++) { //找到数组中第一个为null的位置 if (SongList[i] == null) { SongList[i] = song; success = true; break; } } return success; } //获取当前播放的歌曲：：既然是获取当前播放的歌曲，返回值肯定是Song类型 public static Song GetPlaySong() { if (SongList[SongIndex] != null) { return SongList[SongIndex]; } else { return null; } } /// <summary> /// 播放下一首 /// </summary> public static void MoveOn() { if (SongList[SongIndex] != null && SongList[SongIndex].PlayState == SongPlayState.again) { SongList[SongIndex].SetSongPlayed(); } else { SongIndex++; } } /// <summary> /// 当前播放的歌曲名称 /// </summary> /// <returns>歌曲名称</returns> public static string PlayingSongName() { string songName = ""; // 歌曲名称 if (SongList[SongIndex] != null) { songName = SongList[SongIndex].SongName; } return songName; } /// <summary> /// 下一首要播放的歌曲名称 /// </summary> /// <returns>歌曲名称</returns> public static string NextSongName() { string songName = ""; // 歌曲名称 if (SongList[SongIndex + ] != null) { songName = SongList[SongIndex + ].SongName; } return songName; } //重放当前歌曲 public static void PlayAgain() { if (SongList[SongIndex] != null) { SongList[SongIndex].SetPlayAgain(); } } //切歌 public static void CutSong(int index) { int i;//循环变量，代表切歌的位置 if (index == - )//循环变量，代表切割的位置 { i = SongIndex; } else { i = index;//从切歌的位置开始，将歌曲逐个向前移一个位置 } SongList[i].SetSongCut(); while (SongList[i] != null) { SongList[i] = SongList[i + ]; i++; //如果达到数组最后一个元素，就将最后一个元素指向空 if (i == SongList.Length) { SongList[i] = null; } } } }
