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：

01.歌曲列表

01.代码同为一个歌曲列表窗体

7.字数点歌

01.通过for循环把1-12的数字循环打印出来

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Text;usingSystem.Windows.Forms;usingSystem.Data.SqlClient;namespaceMyKTVClient

for (int i = 0; i < 12; i++)

{//循环生成字数项添加到窗体中

ListViewItem item = newListViewItem();

item.Text= (i + 1) + "个字";

item.Tag= i + 1;

lvlist.Items.Add(item);

}

}//呼叫服务

private void tsbtnService_Click(objectsender, EventArgs e)

{

MessageBox.Show("服务中");

}private void lvlist_Click(objectsender, EventArgs e)

{if (lvlist.SelectedItems[0] != null)

{//读取数据库，读出该歌手的所有歌曲

StringBuilder sb= newStringBuilder();

sb.Append("select song_id,song_name,singer_info.singer_name,song_url,singer_info.singer_photo_url from song_info inner join singer_info on song_info.singer_id=singer_info.singer_id");

sb.AppendFormat("where song_word_count={0}", Convert.ToInt32(lvlist.SelectedItems[0].Tag));

Console.WriteLine(sb.ToString());

frmSongList frm= newfrmSongList();

frm.Sql=sb.ToString();

frm.Onform=FanhuiForm.WordCount;

frm.Show();

}

}// private void tsbtnExit_Click_1(objectsender, EventArgs e)

{this.Close();

}// private void tsbtnOrdered_Click_1(objectsender, EventArgs e)

{

}// //重新播放当前歌曲

{

}private void tsbtnHome_Click(objectsender, EventArgs e)

}private Point mouseOffset; //记录鼠标指针的坐标

mousePos.Offset(mouseOffset.X+ 5, mouseOffset.Y + 30);

Location=mousePos;

}

}private void pnlon_MouseUp(objectsender, MouseEventArgs e)

{//修改鼠标状态isMouseDown的值//确保只有鼠标左键按下并移动时，才移动窗体

if (e.Button ==MouseButtons.Left)

{

isMouseDown= false;

}

}

}

}

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(objectsender, EventArgs e)

{

PlayList.PlayAgain();

PlaySong();

}
