Question

When creating a Configuration object, it asks for a path to a config file… I keep getting an exception thrown for an invalid file path… What’s a valid path? I’ve tried “config.config” and “.\config.config”, but I can’t think of anything else.

If this is for accessing your app.config file, you can use System.Configuration.ConfigurationManager static class, i.e.

var setting = System.Configuration.ConfigurationManager.AppSettings["MySetting"];

Edit: You probably want something like this then:

var configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); // choose ConfigurationUserLevel value, or provide @"c:\path\to\some\exe\"
configuration.AppSettings.Settings.Add("test", "value"); // for new configs
configuration.AppSettings.Settings["test2"].Value = "somevalue"; // for modification of existing keys
c.Save(); // or choose save location
