D:将DateTime转换为Date:无法从DateTime转换为Date

Question

我需要将DateTime类型转换为Date.这是我的代码:

DateTime dt = DateTime(2015, 1, 1, 14, 10, 13);
Date z = cast(Date)dt;

Error: cannot cast from DateTime to Date

怎么了？

Answer 1

DateTime不是Date,你不能投它.要转换,只需访问该DateTime.date()属性:

http://dlang.org/phobos/std_datetime.html#.DateTime.date

const pure nothrow @property @safe Date date();

The date portion of DateTime.
