想了解c#实现KTV点歌系统的相关内容吗，蒲公英学长在本文为您仔细讲解C#实现KTV点歌系统的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：ktv点歌系统,家庭ktv点歌系统，下面大家一起来学习吧。

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;
  }
  }

  {

  }
  else
  {
   SongIndex++;
  }
  }
  /// <summary>
  /// 当前播放的歌曲名称
  /// </summary>
  /// <returns>歌曲名称</returns>
  public static string PlayingSongName()
  {

  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;
   }
  }
  }
 }
