C# Signature:
[DllImport("kernel32.dll")]
static extern int GetTimeFormat(uint locale, uint dwFlags, ref SystemTime time, string format, StringBuilder sb, int sbSize);
User-Defined Types:
SYSTEMTIME in Win32 is different then DateTime in CLR. This structure may represent SYSTEMTIME in CLR world:
[StructLayout(LayoutKind.Sequential)]
private struct SystemTime {
[MarshalAs(UnmanagedType.U2)] public ushort Year;
[MarshalAs(UnmanagedType.U2)] public ushort Month;
[MarshalAs(UnmanagedType.U2)] public ushort DayOfWeek;
[MarshalAs(UnmanagedType.U2)] public ushort Day;
[MarshalAs(UnmanagedType.U2)] public ushort Hour;
[MarshalAs(UnmanagedType.U2)] public ushort Minute;
[MarshalAs(UnmanagedType.U2)] public ushort Second;
[MarshalAs(UnmanagedType.U2)] public ushort Milliseconds;
}
Notes:
Win32 interprets format differently than CLR does so if you don't need exactly Win32 compatible behavior use DateTime.ToString() instead.
Tips & Tricks:
Please add some!
Sample Code:
(see sample code for GetDateFormat())
Alternative Managed API:
DateTime.ToString(string format, IFormatProvider provider);
