从app.config文件中提取连接字符串 [英] Extract connection string from app.config file

问题描述

我正在使用

昏暗的ConStr = configurationmanager.connectionstring("zxcv").tostring

但这不起作用

我正在使用.net framework 3.0 vs 2008

I am using

dim ConStr= configurationmanager.connectionstring("zxcv").tostring

but this is not working

i am using .net framework 3.0 vs 2008

推荐答案

尝试一下:

Try this:

Private Shared Function GetConnectionStringByName( _
    ByVal name As String) As String
    '' Assume failure
    Dim returnValue As String = Nothing
    '' Look for the name in the connectionStrings section.
    Dim settings As ConnectionStringSettings = _
       ConfigurationManager.ConnectionStrings(name)
    '' If found, return the connection string.
    If Not settings Is Nothing Then
        returnValue = settings.ConnectionString
    End If
    Return returnValue
End Function

它直接来自MSDN:存储和检索连接字符串 [ ^ ]

可能值得您下次尝试使用Google ...

It is taken directly from MSDN:Storing and Retrieving Connection Strings[^]

It might be worth your trying Google first, next time...
