File.GetCreationTime Method

Returns the creation date and time of the specified file or directory.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public static DateTime GetCreationTime(
	string path
)

Parameters

path
Type: System.String

The file or directory for which to obtain creation date and time information.

Return Value

Type: System.DateTime
A DateTime structure set to the creation date and time for the specified file or directory. This value is expressed in local time.

ExceptionCondition
UnauthorizedAccessException

The caller does not have the required permission.

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 null.

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.

NotSupportedException

path is in an invalid format.

NoteNote

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 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.

The following example demonstrates GetCreationTime.

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            DateTime fileCreatedDate = File.GetCreationTime(@"C:\Example\MyTest.txt");
            Console.WriteLine("file created: " + fileCreatedDate);
	    }
    }
}
