这是一个KTV点歌系统，分为前台与后台，在后台是对操作人员、歌曲分类、歌曲上传等；前台就是一个KTV点歌功能的实现。
前台界面：

部分代码：

 //数字点歌private void bntNumber_Click(object sender, EventArgs e){Number frm1 = new Number(1);frm1.Owner=this;frm1.ShowDialog();}//拼音点歌private void bntPing_Click(object sender, EventArgs e){Number frm2 = new Number(2);frm2.Owner=this;frm2.ShowDialog();}//明星点歌private void bntAutor_Click(object sender, EventArgs e){Number frm3 = new Number(3);frm3.Owner = this;frm3.ShowDialog();}//歌名点歌private void bntName_Click(object sender, EventArgs e){Number frm4 = new Number(4);frm4.Owner = this;frm4.ShowDialog();}private void frmDaiGe_Load(object sender, EventArgs e){}private void bntEsce_Click(object sender, EventArgs e){DialogResult diaol = MessageBox.Show("是否要退出系统！", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Information);if (diaol == DialogResult.Yes){Application.Exit();}}tbMusicnfoMenthod tbMend = new tbMusicnfoMenthod();private void bntSelect_Click(object sender, EventArgs e){if (stringName != null){stringName = tbMend.tbFillName(stringName);MessageBox.Show("选择歌曲<<" + strigName2 + ">>完成，单击《播放》按钮，播放歌曲！", "提示");}else{MessageBox.Show("请选择要播放的歌曲！","提示");}}private void bntPlay_Click(object sender, EventArgs e){if (stringName != null){Play frm = new Play(stringName);frm.Owner = this;frm.ShowDialog();stringName = null;// lvPlay.SelectedItems[0].Selected = false;}else{MessageBox.Show("请选择要播放的歌曲！","提示");}}string stringName = null;string strigName2 = null;private void lvPlay_Click(object sender, EventArgs e){stringName = lvPlay.SelectedItems[0].SubItems[0].Text;strigName2 = lvPlay.SelectedItems[0].SubItems[1].Text;}
