如何从日期获得DayOfWeek [英] How to get the DayOfWeek from the date

问题描述

例如我把10月20日它给了我星期三

For example i put 10/09/2013 it give me Wednesday

推荐答案

将输入日期字符串解析为DateTime类型，并使用DayOfWeek属性：

Parse the input date string into DateTime type, and use DayOfWeek property:

string day = DateTime.Parse("10/09/2013").DayOfWeek.ToString();

或if你正在文本框控件中输入：

or if you are taking input in a textbox control then:

string day = DateTime.Parse(TextBox1.Text).DayOfWeek.ToString();

输出：day = Wednesday

Output: day = Wednesday

使用 .DayOfWeek 属性

< br $>
请参阅 DateTime.DayOfWeek属性 [ ^ ]



VB示例

Console.WriteLine("The day of the week for {0:d} is {1}.", dt, dt.DayOfWeek.ToString())

结果： 2003年5月1日星期四是星期四。





C＃示例

Result:The day of the week for 5/1/2003 is Thursday.


C# Example

Console.WriteLine("The day of the week for {0:d} is {1}.", dt, dt.DayOfWeek);

< b>结果： 2003年5月1日的星期几是星期四。

Result:The day of the week for 5/1/2003 is Thursday.

var d=new Date();
var weekday=new Array(7);
weekday[0]="Sunday";
weekday[1]="Monday";
weekday[2]="Tuesday";
weekday[3]="Wednesday";
weekday[4]="Thursday";
weekday[5]="Friday";
weekday[6]="Saturday";

var n = weekday[d.getDay()];

< br $>
n 的结果将是：

Wednesday

The result of n will be:
Wednesday
