通过在from dd/MM/yyyy中插入日期来查找星期几 [英] Find day of the week by inserting date in fromat dd/MM/yyyy

问题描述

大家好

我想通过插入日期来获取星期几，但使用格式dd/MM/yyyy

现在这就是我所做的..

< pre lang ="c#"> Session ["StartDate"] = 09/10/2011
字符串ddMMyyyyFormat = Session ["StartDate"].ToString();//dd/MM/yyyy中的日期
字符串MMddyyyFormat = Convert.ToDateTime(ddMMyyyyFormat).ToString("MM/dd/yyyy");

DateTime MMddyyyyDate = Convert.ToDateTime(MMddyyyFormat);
字符串dayOfWeek = MMddyyyyDate.DayOfWeek.ToString();</pre>

现在，我将星期几作为星期六"，因为它没有转换为MM/dd/yyyy

Hi guys

I want to get day of the week by inserting the date but using format dd/MM/yyyy

Now this is what i did..

<pre lang="c#">Session["StartDate"]=09/10/2011
string ddMMyyyyFormat = Session["StartDate"].ToString();//Date in dd/MM/yyyy
string MMddyyyFormat =Convert.ToDateTime(ddMMyyyyFormat).ToString("MM/dd/yyyy");

DateTime MMddyyyyDate = Convert.ToDateTime(MMddyyyFormat);
string dayOfWeek = MMddyyyyDate.DayOfWeek.ToString();</pre>

Now i get the day of the week as "Saturday" because its not converted to format MM/dd/yyyy

推荐答案

session["StartDate"] = 09/10/2011;
string abc = Session["StartDate"].ToString();
DateTime xyz = Convert.ToDateTime(abc);
string dayofweek = xyz.DayOfWeek.toString()

this is working on my machine.

DayOfWeek是一个结构！只需使用int值，然后根据需要设置其格式.演示:

DayOfWeek is a struct! Just use the int value instead and format it as desired. Demonstration:

Console.WriteLine("{0:00}", (int)DateTime.Now.DayOfWeek);
