Tips & Tricks:
Please add some!
Sample Code:
public static DateTime SytemTimeToDateTime(ref SYSTEMTIME st)
{
//malloc the SystemTime structure
int stLen = Marshal.SizeOf(st);
IntPtr pSystemTime = Marshal.AllocHGlobal(stLen);
// copy SystemTime structure to the global heap
Marshal.StructureToPtr(st, pSystemTime, true);
//now malloc the Filetime;
long lFileTime = 0;
int ftLen = sizeof(long);
IntPtr pFileTime = Marshal.AllocHGlobal(ftLen);
//call the kernal32.dll SystemTimToFileTime method
SystemTimeToFileTime(pSystemTime, pFileTime);
//marshal the Filetime back into managed memory
lFileTime = Marshal.ReadInt64(pFileTime);
// convvert filetime to System.DateTime class
DateTime dt = DateTime.FromFileTimeUtc(lFileTime);
//free up resources
Marshal.FreeHGlobal(pSystemTime);
Marshal.FreeHGlobal(pFileTime);
return dt;
}
