想点DataGridView中显示的一行，然后点删除按钮实现删除
求代码

[解决办法]
Private Sub Del_Data()
Dim i As Integer = DataGridView1.Rows.Count
For i = 0 To DataGridView1.Rows.Count - 1
If DataGridView1.Rows(i).Selected Then
Del_Record_DataBase(DataGridView1.Rows(i).Cells(0).Value)
i = DataGridView1.Rows.Count + 1
End If
Next
End Sub
Private Sub Del_Record_DataBase(ByVal id As String)
Dim Conn As OleDbConnection = New OleDbConnection(strCon)
plConn.Open()
Dim strDele As String = "DELETE FROM file WHERE xh= " + id.Trim() + ""
Dim Command As OleDbCommand = New OleDbCommand(strDele, Conn)

Command.ExecuteNonQuery()
Conn.Close()


End Sub

C# code

  private void button1_Click(object sender, EventArgs e)        {            DataRowView rowView = this.dataGridView1.CurrentRow.DataBoundItem as DataRowView;            if (rowView != null)            {                DataRow currentRow = rowView.Row;                //获取主键                string id = currentRow["ID"];                //调用数据库里的删除方法：                string sql = "DELETE FROM TABLE_NAME WHERE ID='" + id + "'";                //数据库操作            }        }
