c# - Accessing App.config in a location different from the binary

Question

In a .NET Win console application, I would like to access an App.config file in a location different from the console application binary. For example, how can C:inText.exe get its settings from C:Test.exe.config?

Answer 1

using System.Configuration;    

Configuration config =
ConfigurationManager.OpenExeConfiguration("C:Test.exe");

You can then access the app settings, connection strings, etc from the config instance. This assumes of course that the config file is properly formatted and your app has read access to the directory. Notice the path is not "C:Test.exe.config" The method looks for a config file associated with the file you specify. If you specify "C:Test.exe.config" it will look for "C:Test.exe.config.config" Kinda lame, but understandable, I guess.
