       var files = Directory.GetFiles(
           this.txtPath.Text.Trim(), 
           "*.config", 
           SearchOption.AllDirectories);
       foreach (string filepath in files)
       {
           string fileName;
           fileName = Path.GetFileName(filepath);
       } 
   }
  </code></pre>
