Relocating app.config file to a custom path

Is it possible to relocate the whole App.Config file to a custom path?

It seems a bit odd that the config file resides in the same folder as the exe, with Windows' new approcah of saving all program settings in c:\ProgramData and all.

An additional requirement we have is to programatically specify where to find the app.config file. The reason for this being that we spawn different service instances from the same exes, and would like to store each service's app.config in that service's settings folder under c:\ProgramData\\.

path app-config .net c#

This is an ancient question, but I ran into this same problem and came up with a hacky workaround from a few minutes in reflector:

static public class ConfigHack {
    static public void OverrideAppConfig(string path) {
        ((AppDomainSetup)
            typeof(AppDomain)
                .GetField("_FusionStore", BindingFlags.NonPublic | BindingFlags.Instance)
                .GetValue(AppDomain.CurrentDomain))
        .ConfigurationFile = path;
    }

    static public void ResetConfigManager() {
        typeof(ConfigurationManager)
            .GetField("s_initState", BindingFlags.Static | BindingFlags.NonPublic)
            .SetValue(null, 0);
    }
}

I've only used it on .NET2, but it looks the same in 4 in reflector. Of course I wouldn't recommend shipping this :P I only use it for quick internal things.
