Parameters

path

The file for which to set the creation date and time information.

creationTimeUtc

A DateTime containing the value to set for the creation date and time of path. This value is expressed in UTC time.

Exception typeCondition

FileNotFoundException

The specified path was not found.

ArgumentException

path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.

ArgumentNullException

path is a null reference (Nothing in Visual Basic).

PathTooLongException

The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.

IOException

An I/O error occurred while performing the operation.

ArgumentOutOfRangeException

creationTime specifies a value outside the range of dates, times, or both permitted for this operation.

UnauthorizedAccessException

The caller does not have the required permission.

NotSupportedException

path is in an invalid format.

The path parameter is permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see GetCurrentDirectory.

NTFS-formatted drives may cache file meta-info, such as file creation time, for a short period of time, which 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.
