有什么更好的方法来删除C＃2.0中文件路径中附加的子文件夹

Question

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

假设EV_HOME返回C：\\ myprogram \\ leanrning \\ anotherfolder

我怎样才能删除anotherfolder文件夹并获取myFilePath这样

C：\\ myprogram \\ leanrning \\ MyFolder \\ MySubFolder

我所知道的是循环Ev_HOME值，并将每个（除了最后一个除外）构建为新字符串。

谢谢。

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication12
{
    class Program
    {
        static void Main(string[] args)
        {
            string EV_HOME = @"C:\myprogram\leanrning\anotherfolder\";
            string parentFolder = new System.IO.DirectoryInfo(EV_HOME).Parent.FullName;
            string myFilePath = parentFolder + "\\MyFolder\\MySubFolder";
            Console.WriteLine(myFilePath);
        }
    }
}
