三天了都没解决的 VS2003类 转到 2005无法使用的问题 有详细说明！
Imports Microsoft.VisualBasic
Imports System.Data.SqlClient
Imports System.IO
Public Class DBController
Private connectingstring As String
Private myConn As SqlConnection
Private ds As Data.DataSet
Private myAdapter As SqlDataAdapter
Private mycmd As SqlCommand
Public Sub New()
System.Configuration.ConfigurationManager.AppSettings( "Connectionstring ").ToString.Trim()
myConn = New SqlConnection(connectingstring)
End Sub
Public Sub open()
myConn.Open()
End Sub
Public Sub close()
myConn.Close()
End Sub
Public Function Getds() As Data.DataSet
Return ds
End Function
'===================================================================
'函数名: Cest （测试模块）

End Sub
这是个数据库连接的类
在2003下 使用正常
2005下 重新命名 而且 System.Configuration.ConfigurationManager.AppSettings( "Connectionstring ").ToString.Trim()
读不出 connectionstring的值 WEB.config正常
2005用什么语句读这个
还有 老是提示需要 NEW重新命名
请问各位大大 如何解决这个问题
我2003的类要重新写了么?
[解决办法]
如果要用ConfigurationManager.AppSettings( "Connectionstring ").ToString.Trim()来取，config里应该写成
<add key= "Connectionstring " value= "test connection string "/>
</appSettings>
