App.config和类库 [英] App.config and class libraries

问题描述

我正在构建一个类库，并希望在

配置文件中存储连接字符串。

我已经读完了，看来这是不可能的，因为通过

设计，类库没有自己的配置文件 - 他们读了

配置文件来自它们所在的应用程序，例如WinForm应用程序

或ASP.NET站点


所以，考虑到这一点，还有另一种解决方案吗？


非常感谢，

Hi,

I am building a class library and want to store a connection string in a
configuration file.

I''ve read around and it appears that this is not possible because "by
design, class libraries don''t have their own config file - they read the
config files from the application they are housed in, such as a WinForm app
or ASP.NET site "

So, with that in mind, is there an alternative solution?

Many thanks,

CR

假设代码在Windows / Web应用程序中使用时才真正使用，所以

使用正在使用你的应用程序的app / web.config文件代码

库

并在那里定义连接字符串？使用注册表？

Presumeably the code is only of real use when used in a Windows/Web app so
use the app/web.config file of the application that is using your code
library
and define the connection string there? Use the registry?

您的.dll（读取.NET代码库）不应该依赖于任何东西。


如果您公开的某个对象需要连接字符串才能工作，那么

应该提供一个属性访问器，以使你的库的用户能够获得/设置字符串。


A .dll应该作为一个黑匣子运作，即你知道你需要把什么放入

，你知道你期望得到什么;任何人使用你的图书馆确实

也不想记得复制配置文件（即使你不想要

这样做）

" CodeRazor"写道：

Your .dll (read .NET code library) should NOT be dependent upon anything.

If one of the objects you expose needs a connection string to work, you
should provide a property accessor to enable the user of your library to
get/set the string.

A .dll should operate as a "black box", i.e. you know what you need to put
in and you know what you expect to get out; anyone using your library does
not want to have to remember to copy the config file too (even you won''t want
to do that)
