我怎样才能让一个.NET类库读取自己的配置文件？ [英] How can I make a .NET class library read its own configuration file?

问题描述

我有一个.NET类库，它提供了一套辅助函数所使用的多种Web服务。此类库必须存储单个设定，具体地，一个连接字符串，其不必由Web看出服务本身，因为它们都必须查询相同datbase

I have a .NET class library that provides a set of helper functions that are used by several Web Services. This class library must store a single setting, specifically, a connection string, which need not be seen by the Web Services themselves, since they all must query the same datbase.

不幸的是，.NET提供了没有办法轻松地阅读一个DLL的的app.config 文件。唯一的易解决方案是将存储在连接字符串中的每一个的Web服务配置文件，这完全是胡说八道。

Unfortunately, .NET provides no means to easily read a DLL's app.config file. The only "easy" solution would be to store the connection string in every single Web Service configuration file, which is completely bollocks.

通常情况下，我在乎code优雅，但是这一次我的真正的需要一个解决方案，哪怕是一个黑客。有没有什么办法让一个.NET类库都有自己的配置？

Normally, I care about code elegance, but this time I really need a solution, even if it is a hack. Is there any way to make a .NET class library have its own configuration?

编辑：从技术上讲，我可以合并所有这些Web服务到一个单一的Web服务。但是，出于商业原因（每个Web服务将被单独出售），我不能这样做。

Technically, I could merge all those Web Services into a single Web Service. But, for business reasons (each Web Service will be sold separately), I cannot do that.

推荐答案

我想你要找的：

ConfigurationManager.OpenExeConfiguration(string exePath)

或

ConfigurationManager.OpenMappedExeConfiguration(
    new ExeConfigurationFileMap() { 
        ExeConfigFilename = path + "app.config" 
    }, ConfigurationUserLevel.None);

它返回一个 配置 对象。 在ConfigurationManager中 MSDN文档

尝试这个问题了解如何获得该DLL的路径。

Try this question for how to get the DLL path.
