Question

   string EV_HOME = System.Environment.GetEnvironmentVariable("EV_HOME");
   string myFilePath = EV_HOME + "\\MyFolder\\MySubFolder";

Suppose EV_HOME return C:\myprogram\leanrning\anotherfolder

How can I remove the folder anotherfolder and get myFilePath as this

C:\myprogram\leanrning\MyFolder\MySubFolder

What I know is loop the Ev_HOME value and build each one (except the last one) as a new string.

thanks.

            string parentFolder = new System.IO.DirectoryInfo(EV_HOME).Parent.FullName;
            string myFilePath = parentFolder + "\\MyFolder\\MySubFolder";
