       DirectoryInfo di = 
       
       
       
       new DirectoryInfo(
       
       
       
       string.Format(
       
       
       
       @"{0}..\..\", Application.StartupPath));
      
      
      
      
     
     
     
     
    
    
    
    

     
     
     
     

      
      
      
      

     
     
     
     
     
     
     
     

      
      
      
      
 
      
      
      
      
     
     
     
     
    
    
    
    

     
     
     
     

      
      
      
      

     
     
     
     
     
     
     
     

      
      
      
      

       
       
       
       di.FullName

       DirectoryInfo info =

       String path = info.Parent.Parent.FullName;
      
      
      
      
     
     
     
     
   
   
   
   
   
   
   
   

3、

string WantedPath = Application.StartupPath.Substring(0,Application.StartupPath.LastIndexOf(@"\"));
