获取连接字符串的提供者详细信息 [英] getting provider details for connection string

问题描述

对于我的连接字符串，我使用以下命令:

Hi ,

for my connection string, I use this:

<connectionstring="provider=microsoft.data.jet.oledb.4.0;data source=|datadirectory|\db.mdb;...... >

I want to know what is the datadirectory while running the application in debug.
how can I do that?

by the way- my connectionstring is in the app.config of a different project ("DAL" project) from my application forms ("app" project)

thanx!

推荐答案

我的内存有点模糊，但是我相信您可以通过以下方式获得DataDirectory的值:

My memory is a bit fuzzy but I believe you can get the value of DataDirectory with:

Dim path As String = CStr(AppDomain.CurrentComain.GetData("DataDirectory"))

我还没有尝试过，只是隐约记得在某个地方看到它.

I haven''t tried it and only vaguely remember seeing it somewhere.
