how to read c# config file of your program with external startup program

Question

I have a project that adds some functionality to Excel. The way it is setup right now, includes adding "C:.....\Excel.exe" as the start action (Under Debug>Start Action>Start external program)

Now I have a config file (app.config), but when I use ConfigurationManager to read the config items, it reads the C:...\Excel.exe.config file instead of Myapplication.exe.config (or app.config)

Is there a way of making it read my application.exe.config? I've tried ConfigurationManager.OpenExeConfiguration() method but it seems that the config items are not enumerable using this method

Answer 1

Use this:

Configuration config = ConfigurationManager.OpenMappedExeConfiguration(new ExeConfigurationFileMap { ExeConfigFilename = "pathToConfigFile" }, ConfigurationUserLevel.None);
