问题描述

你如何兑换



Datetime.UTCnow.Hour



加倍？



UTChour = Cdbl（Datetime.UTCnow.Hour）

UTChour = Cdbl（Datetime.UTCnow.ToString（HH））< br $>


不起作用。

How do you convert

Datetime.UTCnow.Hour

to a double?

UTChour = Cdbl(Datetime.UTCnow.Hour)
UTChour = Cdbl(Datetime.UTCnow.ToString("HH"))

do not work.

推荐答案

它应该 - UTCNow返回一个标准的DateTime，而Hour只返回一个整数 - 所以CDbl只会将 int32 转换为 double 值。

和a快速查看：

It should - UTCNow returns a standard DateTime, and Hour just returns an integer - so CDbl will just convert the int32 to a double value.
And a quick check here:

Dim d As Double = CDbl(DateTime.UtcNow.Hour)

说工作正常...... d 包含18.0，而它是19:26 BST，即GMT + 1或UTC + 1如果您愿意......

Says it works just fine...d contains 18.0, and it's 19:26 BST, which is GMT+1, or UTC+1 if you prefer...
