Do I need to check if directory/file exist or not?

Question

Which one code is better? Code1: ``` if (!Directory.Exists("DirectoryPathHere")) Directory.CreateDirectory("DirectoryPathHere"); ``` Code2: ``` Directory.CreateDirectory("DirectoryPathHere"); ``` I think Code2 because as I saw it not gives any error and its not making new folder when the folder already exists, so I though that checking for folder existence is useless. Right?

Accepted Answer

You don't need to check if the directory already exists, the method does it for you. If you check on MSDN :

Any and all directories specified in path are created, unless they already exist or unless some part of path is invalid. The path parameter specifies a directory path, not a file path. If the directory already exists, this method does not create a new directory, but it returns a DirectoryInfo object for the existing directory.
