c# - Clean approach to finding a folder's parent -

i have piece of code searches folder given starting directory. once folder found need name of it's parent. following piece of code works terribly ugly. have flag, "sessionfound" assist breaking nested foreach loops. following works. hoping eyes on , see if suggestions on how make less verbose , bit more concise.

thanks.

    private void setprojectfolder(string sessionid)         {  //ioc container gives root directory begin search.             string[] supportdirs = directory.getdirectories(applicationcontainer.supportdirectory);             bool sessionfound = false;              foreach (string directory in supportdirs)             {                 if (!sessionfound)                 {                     foreach (string folder in directory.getdirectories(directory))                     {                         if (!sessionfound)                         {                             foreach (string productsubfolder in directory.getdirectories(folder))                             {                                 if (productsubfolder.contains(sessionid))                                 {                                     _productname = directory.getparent(productsubfolder).parent.name;                                     sessionfound = true;                                     break;                                 }                             }                         }                         else                         {                             break;                         }                     }                 }                 else                 {                     break;                 }             }         } 

try this:

private void setprojectfolder(string sessionid)     {         //this simulate contains statement         string searchpattern = string.format("*{0}*", sessionid);         string[] supportdirs = directory.getdirectories(applicationcontainer.supportdirectory, searchpattern);          foreach (string filteredfolder in supportdirs)         {             _productname = directory.getparent(filteredfolder).name;             break;         }     }
