File.GetCreationTimeUtc Method (String)
Returns the creation date and time, in coordinated universal time (UTC), of the specified file or directory.
Assembly: mscorlib (in mscorlib.dll)
The file or directory for which to obtain creation date and time information.
The caller does not have the required permission.
path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.
path is null.
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.
path is in an invalid format.
This method may return an inaccurate value, because it uses native functions whose values may not be continuously updated by the operating system.
If the file described in the path parameter does not exist, this method returns 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC).
NTFS-formatted drives may cache information about a file, 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.
