@msdn=http://search.microsoft.com/search/results.aspx?qu=$$$ @pinvoke=http://pinvoke.net/$$$.htm Summary: The FileTimeToSystemTime API !!!!C# Signature: [DllImport("kernel32.dll", CallingConvention=CallingConvention.Winapi, SetLastError=true)] static extern bool FileTimeToSystemTime([In] ref FILETIME lpFileTime, out SYSTEMTIME lpSystemTime); !!!!VB.Net Signature <DllImport( _ "kernel32.dll", _ CharSet:=CharSet.Auto, _ SetLastError:=True)> _ Friend Shared Function FileTimeToSystemTime( _ <[In]()> ByRef lpFileTime As FILETIME, _ <Out()> ByRef lpSystemTime As SYSTEMTIME) _ As Boolean End Function !!!!User-Defined Types: Structures.[FileTime] and Structures.[SystemTime]. !!!!Notes: By setting the SetLastError property to true, a System.ComponentModel.Win32Exception will generated if the function fails. !!!!Tips & Tricks: For .NET Compact Framework: this function is contained in "coredll.dll" not "kernel32.dll" !!!!Sample Code: If you are trying to parse the Modified (e.g. B0D37BF53EBEC501B5) value in the URL (Shortcut) file you could use the following code: References used for the code below: http://www.fmtz.com/formats/url-file-format/article Structures.[FileTime] page C# public static DateTime FileTimeToSystemTime(string hexTS) { string lowDT = string.Format("{0}{1}{2}{3}", hexTS.Substring(6, 2), hexTS.Substring(4, 2), hexTS.Substring(2, 2), hexTS.Substring(0, 2)); string highDT = string.Format("{0}{1}{2}{3}", hexTS.Substring(14, 2), hexTS.Substring(12, 2), hexTS.Substring(10, 2), hexTS.Substring(8, 2)); FILETIME fileTime; fileTime.dwHighDateTime = int.Parse(highDT, System.Globalization.NumberStyles.HexNumber); fileTime.dwLowDateTime = int.Parse(lowDT, System.Globalization.NumberStyles.HexNumber); long hFT2 = (((long)fileTime.dwHighDateTime) << 32) | ((uint)fileTime.dwLowDateTime); return DateTime.FromFileTimeUtc(hFT2); } !!!!Alternative Managed API: You really do not need to use this function as you could use the FromFileTime or FromFileTimeUtc on DateTime class. Refer to the sample code provided in the Structures.[FileTime] page. Documentation: FileTimeToSystemTime@msdn on MSDN
