第一步:创建数据库连接方法和打开方法和关闭方法!

 1 public partial class FormMain : Form 2   { 3     DBHelper db = new DBHelper(); 4     public FormMain() 5     { 6       InitializeComponent(); 7     } 8     private void Form1_Load(object sender, EventArgs e) 9     {10       //读取路径表中的图片路径放到filepath上11       get='_blank'>string sql = "select resource_path from resource_path where resource_id=1";12       SqlCommand cmd = new SqlCommand(sql,db.Conection);13       db.OpenConnection();14       KtvUtil.FilePath = cmd.ExecuteScalar().ToString();15       db.CloseConnection();16     }17 18     private void pictureBox1_Click(object sender, EventArgs e)19     {20       //打开明星点歌窗体21       FrmSinger frmSinger = new FrmSinger();22       frmSinger.Show();23     }24 25     private void toolStripButton4_Click(object sender, EventArgs e)26     {27       this.Close();28     }29 30     private void pictureBox4_Click(object sender, EventArgs e)31     {32       //打开拼音点歌窗体33       FrmOrderBySongName fobsn = new FrmOrderBySongName();34       fobsn.ShowDialog();35     }

第三步:歌星点歌

歌星点歌:用到了3个ListView之间的跳转,

 1 public partial class FrmSongList : Form 2   { 3     DBHelper db = new DBHelper(); 4     DataSet ds = new DataSet(); 5  6     private string sql = ""; 7     //歌曲的查询语句 8     public string Sql 9     {10       get { return sql; }11       set { sql = value; }12     }13     public FrmSongList()14     {15       InitializeComponent();16     }17    18     private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)19     {20       //第一步判断datagridView有没有选中的行21       //第二步从实例化SongList类22       //第三步调取歌曲song类的字段进行赋值(从datagridview中的列赋值);23       //第四部把从datagridview中获取到的数据添加到播放类里的数组中24       if (this.dataGridView1.SelectedRows[0]!=null)25       {26         SongList song = new SongList();27         song.SongName1 = this.dataGridView1.SelectedRows[0].Cells[1].Value.ToString();28         song.SongUl1 = this.dataGridView1.SelectedRows[0].Cells[3].Value.ToString();29         PalyList.AddSong(song);30       }31       32     }33 34     private void FrmSongList_Load(object sender, EventArgs e)35     {36       SqlDataAdapter sda = new SqlDataAdapter(sql,db.Conection);37       sda.Fill(ds,"songinfo");38       dataGridView1.DataSource = ds.Tables["songinfo"];39     }40 41     private void toolStripButton4_Click(object sender, EventArgs e)42     {43       this.Close();44     }45 46     private void toolStripButton6_Click(object sender, EventArgs e)47     {48       FrmSong frm = new FrmSong();49       frm.ShowDialog();50     }

第五步:已点歌曲

已点歌曲:进入了就是已播放状态一次往下添加都是未播放,如果到了下面的播放状态就还得改变成已播放

 1   public partial class FrmSpeall : Form 2   { 3     private DBOpetion db = new DBOpetion(); 4     private SqlDataAdapter adapter = null; 5     private DataSet ds = new DataSet(); 6     public FrmSpeall() 7     { 8       InitializeComponent(); 9     } 10     [DllImportAttribute("user32.dll")] 11     private static extern bool AnimateWindow(IntPtr hwnd, int dwTime, int dwFlags); 12     private void FrmSpeall_Load(object sender, EventArgs e) 13     { 14       AnimateWindow(this.Handle, 300, FrmMain.AW_SLIDE + FrmMain.AW_VER_POSITIVE); 15     //动态效果可以取消注释 16       //for (int i = 97; i < 123; i++) 17       //{ 18       //  for (int j = 0; j < 4; j++) 19       //  { 20       //    Label label = new Label(); 21       //    label.BackColor = Color.Yellow; 22       //    label.Font=new System.Drawing.Font("宋体",14.25F,System.Drawing.FontStyle.Regular, 23       //      System.Drawing.GraphicsUnit.Point,((byte)(134))); 24       //    label.AutoSize = false; 25       //    label.Size = new System.Drawing.Size(50, 25); 26       //    label.Text = ((char)i).ToString(); 27       //    label.TextAlign = ContentAlignment.MiddleCenter; 28       //    label.Location = new Point(60 + (i * 90), 60 + (j * 60)); 29       //    label.Parent = panel1; 30       //  } 31       //} 32       ////for (int i = 97; i < 123; i++) 33       ////{ 34       ////  Console.WriteLine((char)i); 35       ////} 36     } 37  38     private void pictureBox1_Click(object sender, EventArgs e) 39     { 40       this.textBox1.Text = this.textBox1.Text + "a";
