        Dim insertStatment As String = "INSERT INTO comment (name,comment) VALUES 
        (@name,@comment)"
        cmd2 = New MySqlCommand(insertStatment, db_con)
        cmd2.Parameters.AddWithValue("@name", txtname.Text)
        cmd2.Parameters.AddWithValue("@comment", richtxtcomment.Text)

通常，对于 ComboBox，您需要执行以下操作：

cmd2.Parameters.AddWithValue("@whatever", combobox.SelectedValue);
