Syntax

public static DateTime GetCreationTime (string path)

Parameters

Exceptions

TypeReason
ArgumentException path is a zero-length string, contains only white space, or contains one or more implementation-specific invalid characters.
ArgumentNullException path is null.
System.IO.IOException path was not found.

System.Security.SecurityExceptionThe caller does not have the required permission.
UnauthorizedAccessExceptionThe caller does not have the required permission.

Remarks

Note:

This method may return an inaccurate value, because it uses native functions whose values may not be continuously updated by the operating system.

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 Directory.GetCurrentDirectory.

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), adjusted to local time.

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.
