.NET own configuration file

Question

Is there any way that I could specify at runtime the configuration file I would like to use (other than App.config)? For example I would like to read a first argument from a command line that will be a path to the application's config and I would like my application to refer to it when I use ConfigurationManager.AppSettings (It's probably impossible but still it's worth asking).
I did find this piece of code:

System.Configuration.Configuration config
    = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        config.AppSettings.File = myRuntimeConfigFilePath;
        config.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection("appSettings");

It works, but it overrides the original App.config's AppSettings section and my application isn't supposed to write anything.

I found this and it works. "path" is a path to configuration file.

AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", path);

Not directly.

Indirectly, you could:

spin up a second AppDomain, specify the config-file for that (AppDomainSetup.ConfigurationFile), and execute the code in the app domain
have two exes; the first (foo.exe) simply copies the config (into bar.exe.config) and shells the 2nd exe (bar.exe) [warning: thread race]

That is a big topic... basically, in .NET you have a level of abstraction inside a Process - the AppDomain. See msdn: msdn.microsoft.com/en-us/library/yb506139.aspx

If you're using log4net you can specify your configuration file in the AssemblyInfo.cs

Another solution is to refactor and create your own ConfigurationRepository. Then you can change at runtime what specific repository implementation you will use.

For example, AppConfigRepository : ConfigurationRespository will just be a facade for the old ConfigurationManager.AppSettings["key"].

I already know about it but i'm looking for something simpler so that I don't reinvent the wheel (if it exists ;))
