Copy Directory and Sub Directory

Copy Directory and Sub Directory

Today I will discuss this a method to copy the entire directory along with associated sub directories if required..

Here is the code snippet to achieve this:

    /// <summary>

        /// Copys directory, including sub directories, if desired

        /// </summary>

        /// <param name="theSourcePath"></param>

        /// <param name="theDestPath"></param>

        /// <param name="copySubDirs"></param>

        private static void CopyDirectory(String theSourcePath, string theDestPath, bool copySubDirs)

        {

            var dir = new DirectoryInfo(theSourcePath);

            DirectoryInfo[] dirs = dir.GetDirectories();

            // If the source directory does not exist, throw an exception.

            if (!dir.Exists)

            {

                throw new DirectoryNotFoundException(

                    "Source directory does not exist or could not be found: "

                    + theSourcePath);

            }

            // If the destination directory does not exist, create it.

            if (!Directory.Exists(theDestPath))

            {

                Directory.CreateDirectory(theDestPath);

            }

            // Get the file contents of the directory to copy.

            FileInfo[] files = dir.GetFiles();

            foreach (FileInfo file in files)

            {

                // Create the path to the new copy of the file.

                string temppath = Path.Combine(theDestPath, file.Name);

                // Copy the file.

                file.CopyTo(temppath, false);

            }

            // If copySubDirs is true, copy the subdirectories.

            if (copySubDirs)

            {

                foreach (DirectoryInfo subdir in dirs)

                {

                    // Create the subdirectory.

                    string temppath = Path.Combine(theDestPath, subdir.Name);

                    // Copy the subdirectories.

                    CopyDirectory(subdir.FullName, temppath, true);

                }

            }

        }
