小学生之KTV项目文档(bdqn)
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)

197 }
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 }

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 ? "未播放" : "已播放";
11 lvitem.SubItems.Add(type);
12 this.listView1.Items.Add(lvitem);
13 }
14
15 }

17
18 private void toolStripButton1_Click(object sender, EventArgs e)

4 private SqlDataAdapter adapter = null;
5 private DataSet ds = new DataSet();
6 public FrmSpeall()

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++)
