You can specify the DateTimeKind when you create a new DateTime object, so you could specify that as UTC and then use .ToLocalTime to convert it to local time:

        long dateNumber = 1297380023295;
        long beginTicks = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).Ticks;

        DateTime dt = new DateTime(beginTicks + dateNumber * 10000, DateTimeKind.Utc);
        MessageBox.Show(dt.ToLocalTime().ToString());
