使用ConfigurationManager从任意位置加载配置 [英] Using ConfigurationManager to load config from an arbitrary location

问题描述

我正在开发一个数据访问组件，将在包含经典ASP和ASP.NET页面的网站中使用，需要一个好的方法来管理其配置设置。

I'm developing a data access component that will be used in a website that contains a mix of classic ASP and ASP.NET pages, and need a good way to manage its configuration settings.

我想使用自定义的 ConfigurationSection ，对于ASP.NET页面，这是非常好的。但是当组件通过COM interop从一个经典的ASP页面调用时，该组件不在ASP.NET请求的上下文中运行，因此不知道web.config。

I'd like to use a custom ConfigurationSection, and for the ASP.NET pages this works great. But when the component is called via COM interop from a classic ASP page, the component isn't running in the context of an ASP.NET request and therefore has no knowledge of web.config.

有没有办法告诉 ConfigurationManager 只是从任意路径加载配置（例如 .. \web.config 如果我的程序集在 / bin 文件夹中）？如果有，我想我的组件可以回到，如果默认 ConfigurationManager.GetSection 返回 null for

Is there a way to tell the ConfigurationManager to just load the configuration from an arbitrary path (e.g. ..\web.config if my assembly is in the /bin folder)? If there is then I'm thinking my component can fall back to that if the default ConfigurationManager.GetSection returns null for my custom section.

推荐答案

尝试以下操作：

System.Configuration.ConfigurationFileMap fileMap = new ConfigurationFileMap(strConfigPath); //Path to your config file
System.Configuration.Configuration configuration = System.Configuration.ConfigurationManager.OpenMappedMachineConfiguration(fileMap);
