完成时间3天，四人团队完成
Client前端
1.KTV主页面
1.KTV主界面
客户端进入KTV点歌系统的主窗体，窗体的中部是通过五个 PictureBox 控件，展示了歌星点歌，拼音点歌，类型点歌，热播排行和字数点歌等功能。当单机某个图片时，将会进入到相关的窗体。而窗体的下部使用了 ToolStrip 控件提供了重唱
2.歌星点歌
在主窗体上，单击“歌星点歌”图标就进入了“歌星点歌”窗体，按歌手性别分为组合，女歌手和男歌手三个类型，如图下所示
1.单机某种类型，如“男歌手”图标，窗体将变换为图下所示的页面，在窗体中对歌手所属地区进行了分类。
1.选择某个地区后，如“台湾”后，将显示这个地区的歌手信息，界面效果如图下所示。
1.当单击歌手姓名为“方大同”的歌手时，将显示这名歌手的信息

3.拼音点歌
输入歌曲的名称或歌曲的拼音，单击“查询”按钮，可以进行模糊查询
当你输入“Q”的时候，自动把“Q”开头的歌曲信息查询出来。
当你选择查询的时候也会把符合条件的歌曲信息查询出来显示到列表中

4.类型选择
类型选择提供了歌曲的分类列表（热门流行，经典老歌，影视金曲，游戏动漫，戏曲，儿歌）。
当你选择“热门流行”，将会在窗口下显示这个分类下的歌曲列表，如图下所示：
5.金榜排行
金榜是指将歌曲按点播过的次数，降序排列，作为点歌排行榜，在排行榜中显示了歌曲的名称和歌曲姓名。选择其中一首歌曲，可以进行点播，并把歌曲添加到播放列表中。
类型点歌关键代码： 窗体 FrmOrderBySongType
/// 窗体加载事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void FrmOrderBySongType_Load(object sender, EventArgs e)
{
bindDgvList();
}
string songType;
private void osPopularpop_MouseClick(object sender, MouseEventArgs e)
{
songType = "热门流行";
seek();
}

{

where song_info.singer_id=singer_info.singer_id
and song_info.songtype_id=song_type.songtype_id";
dapter = new SqlDataAdapter(sql, db.Conn);
if (ds.Tables[“songinfo”] != null)
{
ds.Tables[“songinfo”].Clear();
}
dapter.Fill(ds, “songinfo”);
this.dgvsonglist.DataSource = ds.Tables[“songinfo”];
}
catch (Exception ex)
{
MessageBox.Show("异常" + ex.Message);
}
}
/// <summary>

private void seek()
{
DataView dv = new DataView(ds.Tables["songinfo"]);
dv.RowFilter = string.Format("songtype_name='{0}'", songType);
MessageBox.Show(songType);
dgvsonglist.DataSource = dv; //绑定数据源
}
5.字数点歌
进入“字数点歌”窗体后，可以按歌曲名称的字数进行点歌。
当你选择2的时候他会筛选符合字数为2的歌曲并把它显示出来，如图下所示
字数点歌关键代码： 窗体：FrmOrderByWordCount
/// 加载事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void FrmOrderByWordCount_Load(object sender, EventArgs e)
{
this.dgvsonglist.AutoGenerateColumns = false;
bindDgvList();
}
public int number;
//一个字
private void lblone_MouseClick(object sender, MouseEventArgs e)
{
number = 1;
numberChoose();
}
//两个字
private void lbltwo_MouseClick_1(object sender, MouseEventArgs e)
{
number = 2;
numberChoose();
}
//三个字
private void lblthree_MouseClick(object sender, MouseEventArgs e)
{
number = 3;
numberChoose();
}
//四个字
private void lblfour_MouseClick(object sender, MouseEventArgs e)
{
number = 4;
numberChoose();
}
//五个字
private void lblfive_MouseClick(object sender, MouseEventArgs e)
{
number = 5;
numberChoose();
}
//六个字
private void lblsix_MouseClick(object sender, MouseEventArgs e)
{
number = 6;
numberChoose();
}
//七个字
private void lblseven_MouseClick(object sender, MouseEventArgs e)
{
number = 7;
numberChoose();
}
//八个字
private void lbleight_Click(object sender, EventArgs e)
{
number = 8;
numberChoose();
}
//九个字
private void lblnine_MouseClick(object sender, MouseEventArgs e)
{
number = 9;
numberChoose();
}
//全部
private void lblall_Click(object sender, EventArgs e)
{
bindDgvList();
}
DBhepel db = new DBhepel();
private SqlDataAdapter dapter;
DataSet ds = new DataSet();
/// <summary>
/// 绑定歌曲列表
/// </summary>
private void bindDgvList()
{
try
{
string sql = @" select * from song_info,singer_info,song_type
where song_info.singer_id=singer_info.singer_id
and song_info.songtype_id=song_type.songtype_id";
dapter = new SqlDataAdapter(sql, db.Conn);
if (ds.Tables[“songinfo”] != null)
{
ds.Tables[“songinfo”].Clear();
}
dapter.Fill(ds, “songinfo”);
this.dgvsonglist.DataSource=ds.Tables[“songinfo”];
}
catch (Exception ex)
{
MessageBox.Show("异常" + ex.Message);
}
}
/// <summary>
/// 根据字数选择
/// </summary>
private void numberChoose()
{
DataView dv = new DataView(ds.Tables["songinfo"]);
dv.RowFilter = string.Format("song_word_count={0}", number);
MessageBox.Show(number.ToString());
dgvsonglist.DataSource = dv; //绑定数据源
}
