Integer representation for day of the week
提问by THE DOCTOR
I would like to convert a date object its integer representation for the day of week in C#. Right now, I am parsing a XML file in order to retrieve the date and storing that info in a string. It is in the following format:
我想在 C# 中将日期对象转换为星期几的整数表示。现在，我正在解析一个 XML 文件以检索日期并将该信息存储在一个字符串中。它采用以下格式：
"2008-12-31T00:00:00.0000000+01:00"
“2008-12-31T00:00:00.0000000+01:00”
How can I take this and convert it into a number between 1 and 7 for the day of the week that it represents?
我怎样才能把它转换成它所代表的星期几的 1 到 7 之间的数字？

(Int32)Convert.ToDateTime("2008-12-31T00:00:00.0000000+01:00").DayOfWeek + 1

If you load that into a DateTime varible, DateTime exposes an enum for the day of the week that you could cast to int.
如果您将其加载到 DateTime 变量中，则 DateTime 会公开您可以转换为 int 的星期几的枚举。

DateTime date = DateTime.Parse("2008-12-31T00:00:00.0000000+01:00");
int dayOfWeek = (int)date.DayOfWeek + 1; //DayOfWeek is 0 based, you wanted 1 based

(int)System.DateTime.Parse("2008-12-31T00:00:00.0000000+01:00").DayOfWeek + 1
(int)System.DateTime.Parse("2008-12-31T00:00:00.0000000+01:00").DayOfWeek + 1
