如何从当年的特定日期找到日期名称？

Question

I have the birth date from particular year, i want to find the day name of that birth date for current year.

how to do this?

Answer 1

You can find birthdate in this year like;

var birthDate = new DateTime(1983, 10, 21);
var thisYear = new DateTime(DateTime.Today.Year, birthDate.Month, birthDate.Day);

var dayOfWeek = thisYear.DayOfWeek; // it gives you day of week of birth day in this year

Answer 2

只需使用DateTime.DayOfWeek

Answer 3

采用

    string day = DateTime.Now.DayOfWeek.ToString();

Answer 4

I use this Extension Method:

public static string GetDayName(this DateTime date)
{
    string _ret = string.Empty; //Only for .NET Framework 4.0++
    var culture = new System.Globalization.CultureInfo("en-US"); //<- '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;
}

Then we call it:

var birthDate = new DateTime(1983, 10, 21);
var thisYear = new DateTime(DateTime.Today.Year, birthDate.Month, birthDate.Day);

var dayOfWeek = thisYear.GetDayName(); //<- Returns 'Monday'

Answer 5

try this

 string Name = CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(DateTime.Now.DayOfWeek);

Hops its helps
