Modify AppSettings in the App.Config of different Exe

Question

I have a C# .NET Console application exe with an app.config specifying a handful of ApplicationSettings used as parameters.

I have an additional separate (Windows Forms) exe (residing in the same directory) to allow the ApplicationSettings used by the first exe to be modified by the user.

What it the cleanest way to go about modifying the first exe's app.config from the second exe?

Thanks.

Answer 1

you can use

public static Configuration OpenExeConfiguration(
    string exePath
)

Answer 2

Use:

Configuration cfg = ConfigurationManager.OpenExeConfiguration(path_to_exe_file_of_second_app);
// do whatever you need with that configuration
cfg.Save();

Please note that OpenExeConfiguration method takes a path to the second app exe file, not the config file itself.
