什麼是更好的方式來去除附着在文件路徑C＃2.0

Question

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

假設EV_HOME回報下的子文件夾：\ myprogram \ leanrning \ anotherfolder

我怎樣才能刪除該文件夾anotherfolder並獲得myFilePath因爲這

C：\ myprogram \ leanrning \ MyFolder文件\ MySubFolder

我所知道的是循環的Ev_ HOME值並將每個（除最後一個）作爲新字符串構建。

謝謝。

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); 
     } 
    } 
}
