vs2005下怎么读取app.config?
环境vs2005,语言vb.net,用System.Configuration.ConfigurationSettings.GetConfig被提示System.Configuration.Configurationmanage.getsection编译错误
__________________________________________________________________________
救急
__________________________________________________________________________
能看一下那个完整的句子么？
__________________________________________________________________________
dim constr as string
constr=System.Configuration.ConfigurationSettings.GetConfig( "connectstring ").tostring
提示getconfig过时,被System.Configuration.Configurationmanage.getsection取代,但是后者根本通不过编译
__________________________________________________________________________
没有人吗?救急啊,55555555
__________________________________________________________________________
System.Configuration.ConfigurationManager.AppSettings( "connectionString ").ToString
__________________________________________________________________________
编译根本通不过
__________________________________________________________________________
您是用WebForm么？
__________________________________________________________________________
还有通不过显示什么信息？
__________________________________________________________________________
提示Configuration.不能初始化,请问什么意思?我用System.Configuration.Configurationmanage.appsettings.get来读
__________________________________________________________________________
用

Dim str as String = ConfigurationManager.AppSettings( "connectionString ").ToString

就行啦，您的connectionString设置好了吧？

是app.config的问题,已经处理好了,但是我读不出表里数据,但是用sql是可以查询到的
sqlstr = " select * from tbgmtsmpl where ClientName= '' " + Me.txtClientName.Text + " '' "
rs = cn.Execute(sqlstr)
If rs.RecordCount > 0 Then
setForm(rs)
End If
在后台是能查询数据的,请问什么原因?

能请问一下是什么问题么？

System.Configuration.ConfigurationManager.AppSettings( "connectionstring ").ToString

这个可以用么？
