//default locale
System.DateTime.Now.DayOfWeek.ToString();
//localized version
System.DateTime.Now.ToString("dddd");
To make the answer more complete:
为了使答案更完整：
If localization is important, you should use the "dddd" string format as Fredrikpointed out - MSDN "dddd" format article
如果本地化很重要，您应该使用Fredrik指出的“dddd”字符串格式- MSDN“dddd”格式文章

DateTime.Now.DayOfWeekquite easy to guess actually.
DateTime.Now.DayOfWeek其实很容易猜到。

对于任何给定日期：
DateTime dt = //....
DayOfWeek dow = dt.DayOfWeek; //enum

If you want to know the day of the week for your code to do something with it, DateTime.Now.DayOfWeekwill do the job.
如果你想知道你的代码在一周中的哪一天用它做某事，就DateTime.Now.DayOfWeek可以完成这项工作。
If you want to display the day of week to the user, DateTime.Now.ToString("dddd")will give you the localized day name, according to the current culture (MSDN info on the "dddd" format string).
如果您想向用户显示星期几，DateTime.Now.ToString("dddd")则会根据当前文化（“dddd”格式字符串上的 MSDN 信息）为您提供本地化的日期名称。

What about if we use String.Format here
如果我们在这里使用 String.Format 呢？
DateTime today = DateTime.Today;
String.Format("{0:dd-MM}, {1:dddd}", today, today) //In dd-MM format
String.Format("{0:MM-dd}, {1:dddd}", today, today) //In MM-dd format回答by Abhendra Tiwari
(DateTime.Parse((Eval("date").ToString()))).DayOfWeek.ToString()
at the place of Eval("date"),you can use any date...get name of day
在Eval("date") 的位置，您可以使用任何日期...获取日期名称

I use this Extension Method:
我使用这个扩展方法：
public static string GetDayName(this DateTime date)
{
string _ret = string.Empty; //Only for .NET Framework 4++
var culture = new System.Globalization.CultureInfo("es-419"); //<- 'es-419' = Spanish (Latin America), 'en-US' = English (United States)
_ret = culture.DateTimeFormat.GetDayName(date.DayOfWeek); //<- Get the Name
_ret = culture.TextInfo.ToTitleCase(_ret.ToLower()); //<- Convert to Capital title
return _ret;
}
