asp.net - How to move a directory

Move a directory to a new path

.Net framework DirectoryInfo.MoveTo() method allow us to move a DirectoryInfo instance and its contents to a new path. DirectoryInfo class MoveTo() method exists in System.IO namespace.

DirectoryInfo MoveTo() method require to pass a parameter named 'destDirName'. this 'destDirName 'parameter value data type is System.String which represents the name and path to which to move this directory. the destination can be an existing directory to which we want to add the source directory as a sub directory.

MoveTo() method throw ArgumentNullException exception, if the 'destDirName' is null. it throw ArgumentException, if the 'destDirName' is an empty string. method throw IOException, if an attempt was made to move a directory to a different volume or 'destDirName' already exists or caller are not authorized to access this path or source and destination directory have the same name.

MoveTo() method throw SecurityException, if the caller does not have the required permission. method also throw DirectoryNotFoundException, if the destination directory cannot be found.

.Net framework Directory class Directory.Move() method also allow us to move a file or directory and its contents to a new location. this method has two required parameter named 'sourceDirName' and 'destDirName'.

the following asp.net c# example code demonstrate us how can we move a directory to a specified path programmatically at run time in an asp.net application.
