使用ConfigurationManager中从多个web.config文件中读取 [英] Using configurationmanager to read from multiple web.config files

问题描述

背景：

我在存储约100 Web应用程序的web.config文件中的一些数据，多数民众赞成。这个数据是越来越移到数据库逐步显现。该网页将显示在web.config数据，直到有人点击编辑链接在这种情况下，他们会被重定向到一个网页，这将使他们能够更新这一数据在那里将被保存在一个数据库来代替。

问题：

并非所有数据都将这个页面，将其保存到数据库中进行更改。当有人点击编辑链接，我希望表单从web.config文件中的数据填充，当他们点击保存把它保存到数据库中。但是，使用ConfigurationManager中，我只能得到它从当前应用程序的web.config文件中提取数据。

问题：

1. 有没有办法使用ConfigurationManager中选择web.config文件从可以说 ../ {} dynamic_app_id /web.config ？
办法

2. 是阅读他们作为普通的XML文件，我唯一的选择？


3. 是否有任何陷阱，以这种方式？


4. 有另一种解决方案，能够更好地工作吧？

解决方案

您可以阅读轻松的配置文件。请参阅我的样品code，其中我读到从外部app.config文件的应用程序设置：

  System.Configuration.KeyValueConfigurationCollection设置;
        System.Configuration.Configuration配置;        System.Configuration.ExeConfigurationFileMap CONFIGFILE =新System.Configuration.ExeConfigurationFileMap（）;
        configFile.ExeConfigFilename =my_file.config;
        配置= System.Configuration.ConfigurationManager.OpenMappedExeConfiguration（CONFIGFILE，System.Configuration.ConfigurationUserLevel.None）;
        设置= config.AppSettings.Settings;
 

快乐编码和最诚挚的问候！

Background:

I have some data thats stored in the web.config files of about 100 web applications. This data is getting moved to a database gradually. The webpages will show the web.config data until somebody clicks on an "edit" link in which case they'll be redirected to a webpage which will allow them to update this data where it will be saved in a database instead.

Problem:

Not all of the data will be changed on this page that will save it to the database. When somebody clicks the "edit" link I want the form to populate with the data from the web.config file and when they click "save" have it save to the database. However, using the configurationmanager I can only get it to pull data from the web.config file on current application.

Questions:

1. Is there a way to use configurationmanager to select the web.config file from lets say ../{dynamic_app_id}/web.config ?
2. is reading them as plain xml files my only option?
3. Are there any pitfalls to this approach?
4. Is there another solution that would work better perhaps?

解决方案

You can read any config file with ease. Please see my sample code where I read application settings from external app.config file:

        System.Configuration.KeyValueConfigurationCollection settings;
        System.Configuration.Configuration config;

        System.Configuration.ExeConfigurationFileMap configFile = new System.Configuration.ExeConfigurationFileMap();
        configFile.ExeConfigFilename = "my_file.config";
        config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(configFile, System.Configuration.ConfigurationUserLevel.None);
        settings = config.AppSettings.Settings;

Happy coding and best regards!
