It depends on where in the world you are and what your computer clock is set up to.

It returns the value of the <a href="http://msdn.microsoft.com/en-us/library/system.dayofweek.aspx" rel="nofollow"><code>DayOfWeek</code></a> enum corresponding to the time it was run, plus 1. Sunday is 0, Saturday is 6.

So, for Thursday, <code>dayOfWeekIndex</code> would be 5.

blocks|key|1890471|text|根据MSDN的说法：“DayOfWeek枚举中的常量的值范围从DayOfWeek.Sunday到DayOfWeek.Saturday。如果强制转换为整数，则其值的范围为0。”|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1890472|所以你可以看到枚举的用法，它被转换为int。对于周日%2B1=1+...|1890473|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

According to MSDN: "The value of the constants in the DayOfWeek enumeration ranges from DayOfWeek.Sunday to DayOfWeek.Saturday. If cast to an integer, its value ranges from zero"

So you see usage of enumeration that is casted to int.
For Sunday + 1 = 1

blocks|key|4658532|text|DateTime.Now返回当前日期。DayOfWeek属性以枚举值的形式返回该日期的星期几(星期一、星期二等)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4658533|对Int32的强制转换会将枚举值转换为一个整数(其中sunday+=+0)。|4658534|然后添加1，因此周日将结束为1，周四将结束为5。|4658535|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

DateTime.Now returns the current date. The DayOfWeek property returns the day-of-the-week (monday, tuesday, etc) of that date as an enum value.

The cast to Int32 turns that enum value into an int (where sunday = 0).

Then 1 is added so sunday will end up as 1 and thursday as 5.

blocks|key|1886368|text|etch是一周中各天的枚举，其值包括DayOfWeek.Monday、DayOfWeek.Tuesday+DateTime.DayOfWeek。它的底层类型是整数，这是枚举的默认类型。因此，此代码将返回当前日期的基础整数加1。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1886369|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

DateTime.DayOfWeek is an enum for the days of the week with values such as DayOfWeek.Monday, DayOfWeek.Tuesday etch. It's underlying type is integers which is the default for enums. Therefore this code will return the underlying integer for whichever day it current is plus one.

An enumerated constant that indicates the day of the week of this DateTime value.

The value of the constants in the DayOfWeek enumeration ranges from DayOfWeek.Sunday to DayOfWeek.Saturday. If cast to an integer, its value ranges from zero (which indicates DayOfWeek.Sunday) to six (which indicates DayOfWeek.Saturday).

SO today being thursday means that DayOfWeek will be 4. So day of week+1 will be 5.

I did not run this code. I just used google and msdn.

我想理解c#中的一句话，Int32 dayOfWeekIndex = (Int32)DateTime.Now.DayOfWeek + 1;例如，如果我们今天运行它，返回的结果是什么？我没有运行此代码的选项。
