How to specify path in .config file relative to the file?

Question

An app I use interprets a .NET .config file. I added a line specifying the path to a certificate it needs

Answer 1

I think in your case you need set file name. Folder where all files you know (if folder can be canged - set folder without ../)

And where you need use path - combine current location of application(can be got in runtime ) and key from settings

or use

System.Web.HttpContext.Current.Server.MapPath("~/[PARTH_TO_FILE]") '
