/** @property */ public DateTime get_CreationTimeUtc () /** @property */ public void set_CreationTimeUtc (DateTime value)
public function get CreationTimeUtc () : DateTime public function set CreationTimeUtc (value : DateTime)
Property ValueThe creation date and time in UTC format of the current FileSystemInfo object.
When first called, FileSystemInfo calls Refresh and returns the cached information on APIs to get attributes and so on. On subsequent calls, you must call Refresh to get the latest copy of the information.
If the file described in the FileSystemInfo object does not exist, this property will return 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC).
NTFS-formatted drives may cache file meta-info, such as file creation time, for a short period of time. This process is known as file tunneling. As a result, it may be necessary to explicitly set the creation time of a file if you are overwriting or replacing an existing file.
This property value is a null reference (Nothing in Visual Basic) if the file system containing the FileSystemInfo object does not support this information.
