Question

我想在项目中的任何位置使用dbConnectDBOStr连接字符串，这样如果数据库连接发生更改，我只需要在一个文件中更改它

目前这是一个错误，任何人都知道我做错了什么？

请帮助我真的坚持这个谢谢!!

的Default.aspx

Imports Pirelli.dbPirelli
Partial Class _Default
Inherits System.Web.UI.Page
Sub Page_Load(ByVal Sender As Object, ByVal E As EventArgs) Handles MyBase.Load
    Dim strCmd As String
    Dim dbCmd As SqlCommand
    Dim oConn As SqlConnection
    Dim dbReader As SqlDataReader
    oConn = New SqlConnection(dbConnectDBOStr)

dbPirelli.vb

Imports System.Data.SqlClient
Namespace Pirelli
Public Class dbPirelli
   'Database Server - ENABLE ONE ONLY
    Public Const strServerName As String = "[Server]"  'DEV
    Public Const dbConnectDBOStr As String = "uid=[USER];password=[PASS];database=[DB];server=" & strServerName & ";Connection Timeout=60;"
End Class
End Namespace
