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;
}
