VB.NET中datagridview表里的数据怎样写入到数据库中,请给出实际操作代码，不要理论说说的道理，谢谢

参考技术A Public Class datafrm
Dim conn As SQLite.SQLiteConnection
Dim cmd As SQLite.SQLiteCommand
Dim ap As SQLite.SQLiteDataAdapter
Dim mytable As New DataTable
Private Sub datafrm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
conn = New SQLite.SQLiteConnection("data source=InfoCenter.db")
cmd = New SQLite.SQLiteCommand("select * from leader", conn)
ap = New SQLite.SQLiteDataAdapter(cmd)
conn.Open()
ap.Fill(mytable)
DataGridView1.DataSource = mytable
End Sub
'更新操作

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim sd As New SQLite.SQLiteCommandBuilder(ap)
ap.Update(mytable)
End Sub
End Class本回答被提问者采纳

关于VB.NET中 datagridview 刷新问题

参考技术A 把连接数据库和显示数据的过程写成在一个方法里(如showdata),在点击录入按钮时,先写你的录入代码,写完后在调用一下showdata()
