Sets the date and time, in Coordinated Universal Time (UTC), that the file was created.

public:
 static void SetCreationTimeUtc(System::String ^ path, DateTime creationTimeUtc);

Public Shared Sub SetCreationTimeUtc (path As String, creationTimeUtc As DateTime)

Parameters

path

String

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

creationTimeUtc

DateTime

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

Exceptions

FileNotFoundException

The specified path was not found.

ArgumentException

.NET Framework and .NET Core versions older than 2.1: path is a zero-length string, contains only white space, or contains one or more invalid characters. You can query for invalid characters by using the GetInvalidPathChars() method.

ArgumentNullException

path is null.

PathTooLongException

The specified path, file name, or both exceed the system-defined maximum length.

IOException

An I/O error occurred while performing the operation.

ArgumentOutOfRangeException

creationTimeUtc 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.

Remarks

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. 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.

For a list of common I/O tasks, see Common I/O Tasks.
