xtd::string xtd::io::file_info::directory_name

(

)

const

Gets a string representing the directory's full path.

Returns

A string representing the directory's full path.

Exceptions

xtd::security::security_exception	The caller does not have the required permission.
xtd::io::path_too_long_exception	The specified path, file name, or both exceed the system-defined maximum length.

Exemple

The following example retrieves the full path of the specified file.

string file_name = R"(C:\TMP\log.txt)";
file_info file_info(file_name);
if (!file_info.exists())
  return;
 
console::write_line("{0} has a directoryName of {1}", file_name, file_info.directory_name());
/* This code produces output similar to the following,
 * though actual results may vary by machine:
 *
 * C:\TMP\log.txt has a directory name of C:\TMP
 *‍/

Remarks

To get the parent directory as a xtd::io::directory_info object, use the xtd::io::file_info::directory property.

When first called, xtd::io::file_info calls xtd::io::file_info::refresh and caches information about the file. On subsequent calls, you must call xtd::io::file_info::refresh to get the latest copy of the information.
