如何指定数据库的路径 [英] How to specify the path to my database

问题描述

大家好，

我试图将数据插入我的数据库文件* .sdf

所以，如果我在d：\ project中有.sdf文件\ MyWPF \ App_Data \ Modeld.sdf

理想情况下我的连接字符串是什么。



理想情况下这条路径是正确的：

| DataDirectory | \ App_Data \Mydb.sdf



如果我在调试模式下构建应用程序：那么在我的bin文件夹中让App_data \ MyDb.sdf得到更新，我的原始文件在

d：\projects \ MyWPF \ App_Data \ Modeld.sdf中有时无法正确更新。



每个人都给我的连接字符串为| DataDirectory | \ App_Data \Mydb.sdf



CAn any请告诉我哪里出错了？

Hi All,
I am trying to inset data into my database file *.sdf
So, if i have the .sdf file in d:\projects\MyWPF\App_Data\Mydb.sdf
Ideally What shall be my connection string.

Ideally is this path correct:
|DataDirectory|\App_Data\Mydb.sdf

If i am building my application in Debug mode: then in my bin folder i have App_data\MyDb.sdf that is getting updated and my original file in
d:\projects\MyWPF\App_Data\Mydb.sdf is sometime not getting updated properly.

Everyehere i have given the connection string as |DataDirectory|\App_Data\Mydb.sdf only

CAn anyone pls let me know where i am going wrong??

推荐答案

嗯... D：\Projects \ MyWPF \不太可能是你的数据目录 - 这很可能会导致问题安装在另一台机器上的产品 - 因为您的应用程序将位于Program Files文件夹中并出于安全原因编写难以或不可能的内容。



有一个看看这个：我应该在哪里存储我的数据？ [ ^ ] - 它建议一些适合开发和发布的更好的地方。

Um...D:\Projects\MyWPF\ is very unlikely to be your data directory - and it's very, very likely to cause problems in production when installed on another machine - because your app will be in the "Program Files" folder and writing that that is either difficult or impossible for security reasons.

Have a look at this: Where should I store my data?[^] - it suggests some better places which would be appropriate for development and release.
