C# Definition:

struct FILETIME {

    public uint DateTimeLow;
    public uint DateTimeHigh;

}

VB.Net Definition:

Structure FILETIME
   Public dwLowDateTime As Integer
   Public dwHighDateTime As Integer
End Structure

Alternative Managed Definition:

System.Runtime.InteropServices.FILETIME, or System.Runtime.InteropServices.ComTypes.FILETIME in the .NET Framework 2.0.

Notes:

None.

Sample Code:

There is no reason not to use System.Runtime.InteropServices.FILETIME, but there still is a need for conversion to DateTime:

C#

    public static DateTime FiletimeToDateTime(FILETIME fileTime) {
        long hFT2 = (((long) fileTime.dwHighDateTime) << 32) + fileTime.dwLowDateTime;
        return DateTime.FromFileTimeUtc(hFT2);
    }

    public static FILETIME DateTimeToFiletime(DateTime time) {
        FILETIME ft;
        long hFT1 = time.ToFileTimeUtc();
        ft.dwLowDateTime = (int) (hFT1 & 0xFFFFFFFF);
        ft.dwHighDateTime = (int) (hFT1 >> 32);
        return ft;
    }
