关于c＃：根据Ticks给出不正确的值构造DatetimeOffset对象


Constructing DatetimeOffset object based on Ticks giving incorrect value

DateTimeOffset值要存储在数据库表：我as belowP＞＜／

1
2002-08-27 07:49:20.3190000 -11:00

现在这样的值：在binary filewrite thisP＞＜／

1
2
3
DateTimeOffset d ="2002-08-27 07:49:20.3190000 -11:00";
BinaryWriter w ;
w.Write(d.Ticks);

现在，当我试图使用二进制阅读器读取这个值，那么它是生成基于Ticks类：incorrectly belowP＞＜／

1
2
3
BinaryReader r;
var dateTime = DateTime.FromBinary(r.ReadInt64());
return new DateTimeOffset(dateTime);

输出：8/27/2002 7:49:20 AM +05:30P＞＜／

这是如何发生的？P＞＜／

how to construct DateTimeOffset对象基于ticks properly精确吗？P＞＜／

您需要同时存储UTC刻度和时区偏移量：

1
2
3
4
5
6
7
8
9
DateTimeOffset d ="2002-08-27 07:49:20.3190000 -11:00";
BinaryWriter w;
w.Write(d.Ticks);
w.Write(d.Offset.Ticks);

BinaryReader r;
var dateTime = new DateTime(r.ReadInt64());
var offset = new TimeSpan(r.ReadInt64());
return new DateTimeOffset(dateTime, offset);
