copying msdn, there following solution. recursively copies directories on source destination.

using system; using system.io;  class directorycopyexample {     static void main()     {         // copy current directory, include subdirectories.         directorycopy(".", @".\temp", true);     }      private static void directorycopy(string sourcedirname, string destdirname, bool copysubdirs)     {         // subdirectories specified directory.         directoryinfo dir = new directoryinfo(sourcedirname);         directoryinfo[] dirs = dir.getdirectories();          if (!dir.exists)         {             throw new directorynotfoundexception(                 "source directory not exist or not found: "                 + sourcedirname);         }          // if destination directory doesn't exist, create it.          if (!directory.exists(destdirname))         {             directory.createdirectory(destdirname);         }          // files in directory , copy them new location.         fileinfo[] files = dir.getfiles();         foreach (fileinfo file in files)         {             string temppath = path.combine(destdirname, file.name);             file.copyto(temppath, false);         }          // if copying subdirectories, copy them , contents new location.          if (copysubdirs)         {             foreach (directoryinfo subdir in dirs)             {                 string temppath = path.combine(destdirname, subdir.name);                 directorycopy(subdir.fullname, temppath, copysubdirs);             }         }     } }
