คือตอนนี้ ผมอยากทราบการเขียน sqlreader อะครับ เขียนให้มัน read textbox ไปหาบน table

Dim connection As New SqlConnection
        Dim command As New SqlCommand
        Dim command2 As New SqlCommand


        connection.ConnectionString = "Server=XXXX;UID=sa;PASSWORD=XXXXX;Database=XXXXX;Max Pool Size=400;Connect Timeout=600;"
        connection.Open()
        command2.Connection = connection
        command2.CommandType = CommandType.Text
        command2.CommandText = "INSERT INTO UserInfo (fdUID,UserPass,UserEmail,UserPass2,fdAuthUserNum) VALUES ('" + Form2.TextBoxX1.Text + "','" + Form2.TextBoxX2.Text + "','" + Form2.TextBoxX3.Text + "','" + Form2.TextBoxX4.Text + "','" + Form2.TextBoxX5.Text + "')"

        Try
            If (Conversions.ToInteger(command2.ExecuteNonQuery) > 0) Then
                Interaction.MsgBox("You account have been registered.", MsgBoxStyle.Information, "FunZ")


            Else
                Interaction.MsgBox("Register failed.", MsgBoxStyle.Critical, "Error 108 !")
            End If
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try

        connection.Close()
        connection = Nothing
