xtd::io::directory_info::file_system_info_iterator xtd::io::directory_info::enumerate_file_system_infos

(

)

const

Returns an enumerable collection of file system information in the current directory.

Returns

An xtd::io::directory_info::file_system_info_iterator of file system information in the current directory.

Exceptions

xtd::io::directory_not_found_exception	The specified path is invalid, such as being on an unmapped drive.
xtd::security::security_exception	The caller does not have code access permission to create the directory.

Remarks

The xtd::io::directory_info::enumerate_file_system_infos and xtd::io::directory_info::get_file_system_infos methods differ as follows:

• When you use xtd::io::directory_info::enumerate_file_system_infos, you can start enumerating the collection of xtd::io::directory_info objects before the whole collection is returned.
• When you use xtd::io::directory_info::get_file_system_infos, you must wait for the whole array of xtd::io::directory_info objects to be returned before you can access the array.

Therefore, when you are working with many files and directories, xtd::io::directory_info::enumerate_file_system_infos can be more efficient.

This method pre-populates the values of the following xtd::io::directory_info properties:

• xtd::io::file_system_info::attributes
• xtd::io::file_system_info::creation_time
• xtd::io::file_system_info::last_access_time
• xtd::io::file_system_info::last_write_time
• xtd::io::file_system_info::size
