一个项目，一分收获；一个项目，一些资源。Ktv项目也是一样的，所以我想分享我的收获，让你们获得你需要的资源。
一. 那MyKTV点歌系统具体的功能有哪些呢？我们就来看看吧!
1.MyKTV前台功能：
01.歌星点歌 、拼音点歌 、数字点歌 、类型选择 、金榜排行
02.切歌 、点歌 、重唱和退出
2.MyKTV后台功能：
01.歌手管理 、歌曲管理 、设置资源路径
02.新增歌手、歌曲 ,查询歌手、歌曲信息，设置歌曲路径和退出
二. 功能已经概括的差不多了,就让我们一起来看看MyKTV的项目吧
1.首先就是展现KTV的主界面，让我们先了解一下那些功能
01.实现各个共功能的主代码：

02.歌曲列表
03.已点列表
8.最后再看看重唱的功能展示以及代码
01.重唱
// 重新播放当前歌曲
private void tsbtnAgain_Click(object sender, EventArgs e)
{
