第一步:创建数据库连接方法和打开方法和关闭方法!
1 public class DBHelper 2 { 3 private string str = "server=.;database=MyKtv;uid=sa"; 4 private SqlConnection _conection; 5 6 public SqlConnection Conection 7 { 8 get 9 {10 if (_conection==null)11 {12 _conection = new SqlConnection(str);13 }14 return _conection;15 }16 }17 /// <summary>18 /// 打开方法19 /// </summary>20 public void OpenConnection() 21 {22 if (Conection.State == ConnectionState.Closed)23 {24 Conection.Open();25 } if (Conection.State == ConnectionState.Broken)26 {27 Conection.Close();28 Conection.Open();29 }30 }31 /// <summary>32 /// 关闭方法`33 /// </summary>34 public void CloseConnection() 35 {36 if (Conection.State == ConnectionState.Open && Conection.State == ConnectionState.Broken)37 {38 Conection.Close();39 }40 41 }
第二步:歌曲首页
歌曲首页:用到了窗体之间的转换和读取路径表中的图片路径放到filepath上
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 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 FrmSinger : Form 2 { 3 DBHelper db = new DBHelper(); 4 public string SingerType = "组合"; 5 public int SingerId = 0; 6 7 public FrmSinger() 8 { 9 InitializeComponent(); 10 } 11 12 private void panel1_Paint(object sender, PaintEventArgs e) 13 { 14 15 } 16 /// <summary> 17 /// 点击歌手类型后加载相应的信息 18 /// </summary> 19 public void ShowSingerDiQu() 20 { 21 if (lvtype.SelectedItems[0]!=null) 22 { 23 lvtype.Visible = false; 24 lvSinger.Visible = true; 25 lvSinger.Location = lvtype.Location; 26 27 28 this.SingerType = Convert.ToString(lvtype.SelectedItems[0].Tag); 29 } 30 string sql = "select singertype_name,singertype_id from singer_type"; 31 SqlCommand cmd = new SqlCommand(sql,db.Conection); 32 SqlDataReader sdr; 33 try 34 { 35 db.OpenConnection(); 36 sdr = cmd.ExecuteReader(); 37 lvtype.Items.Clear(); 38 if (sdr.HasRows) 39 { 40 int result = 0; 41 while (sdr.Read()) 42 { 43 ListViewItem lvitem = new ListViewItem(); 44 string typename = Convert.ToString(sdr["singertype_name"]); 45 int typeid = Convert.ToInt32(sdr["singertype_id"]); 46 lvitem.Text = typename; 47 lvitem.Tag = typeid; 48 lvitem.ImageIndex = result; 49 lvSinger.Items.Add(lvitem); 50 result++; 51 } 52 sdr.Close(); 53 } 54 } 55 catch (Exception ex) 56 { 57 MessageBox.Show("第二个系统报错" + ex.Message); 58 } 59 finally 60 { 61 db.CloseConnection(); 62 } 63 } 64 65 private void listView2_SelectedIndexChanged(object sender, EventArgs e) 66 { 67 68 } 69 70 private void FrmOrderBySinger_Load(object sender, EventArgs e) 71 { 72 this.lvSinger.Visible = false; 73 this.lvContry.Visible=false; 74 } 75 76 private void listView1_Click(object sender, EventArgs e) 77 { 78 ShowSingerDiQu(); 79 } 80 /// <summary> 81 /// 读取对应地区的歌手名称 82 /// </summary> 83 public void ShowSingerName() 84 { 85 if (lvSinger.SelectedItems[0]!=null) 86 { 87 lvSinger.Visible = false; 88 lvContry.Visible = true; 89 lvContry.Location = lvtype.Location; 90 SingerId = Convert.ToInt32(lvSinger.SelectedItems[0].Tag); 91 StringBuilder sb = new StringBuilder(); 92 string sum = SingerType; 93 if (sum!="组合") 94 { 95 sum = SingerType == "女歌手" ?

第四步:歌曲列表
双击DateGrilView选中的一行,提示:
歌曲列表:实现点击一下歌曲列表中的一行信息就到以点里面
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 private void FrmOrderedSongList_Load(object sender, EventArgs e) 2 { 3 //遍历播放类里面的数组 4 foreach (SongList item in PalyList.song) 5 { 6 7 if (item!=null) 8 { 9 ListViewItem lvitem = new ListViewItem(item.SongName1);10 string type = item.PlaySong == PalySongState.unplayed ?
