public: static DateTime GetCreationTimeUtc(System::String ^ path);
public static DateTime GetCreationTimeUtc (string path);
static member GetCreationTimeUtc : string -> DateTime
Public Shared Function GetCreationTimeUtc (path As String) As DateTime
The file or directory for which to obtain creation date and time information.
A DateTime structure set to the creation date and time for the specified file or directory. This value is expressed in UTC time.
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.
The specified path, file name, or both exceed the system-defined maximum length.
path is in an invalid format.
The following example demonstrates the GetCreationTimeUtc method.
Imports System.IO Module Module1 Sub Main() Dim fileCreatedDate As DateTime = File.GetCreationTimeUtc("C:\Example\MyTest.txt") Console.WriteLine("file created: " + fileCreatedDate) End Sub End Module
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.
