Get 2 or many coming fridays dates from current date c#-CodePudding

I am working on a module (scheduler). If I add scheduler and I select 2 or many tuesdays from current date to schedule my task. And It will show my task on scheduler for coming 2 or many tuesdays. How can I code this.

To get 2 or many tuesdays from current date. C# or jquery

I have seen many codes but these are not fulfilling my condition.

Var date = new date()

You can try this:

        DateTime dtFrom = DateTime.Today;  // any starting date

        int NextWeekDay = 5; // 1=Sun, 7=sun, so look for Friday's
        int HowMany = 3;     // how many to get

        NextWeekDay = NextWeekDay - (int)dtFrom.DayOfWeek;
        if (NextWeekDay < 0)
            NextWeekDay  = 7;

        DateTime dtStart = dtFrom.AddDays(NextWeekDay);
        for (int i=0; i < HowMany; i  )
        {
            DateTime MyDate = dtStart.AddDays(i * 7);
            Debug.Print(MyDate.ToLongDateString());
        }

output:

Friday, December 9, 2022
Friday, December 16, 2022
Friday, December 23, 2022

So, today is Saturday Dec 3rd, and I count/include today if the requested starting date is same date.

To obtain 2 or many upcoming day of the week (e.g. Tuesday) dates from the current date to schedule, you can the concept in the console example below.

Demo: https://dotnetfiddle.net/UrUrS2

Pass to the ReturnNextNthWeekdaysOfMonth function the following inputs:

starting date e.g. DateTime.Now
day of the week e.g. DayOfWeek.Tuesday
amount of schedule dates to obtain e.g. 2

The result will be the dates to schedule.

public class Program
{
    public static void Main()
    {
        var scheduleDates = ReturnNextNthWeekdaysOfMonth(
            DateTime.Now, DayOfWeek.Tuesday, 2);

        foreach (var date in scheduleDates) Console.WriteLine(date.ToString("f"));
    }

    private static IEnumerable<DateTime> ReturnNextNthWeekdaysOfMonth(
        DateTime dt, DayOfWeek weekday, int amounttoshow = 4)
    {
        // Find the first future occurance of the day.
        while (dt.DayOfWeek != weekday)
            dt = dt.AddDays(1);

        // Create the entire range of dates required. 
        return Enumerable.Range(0, amounttoshow).Select(i => dt.AddDays(i * 7));
    }
}

Output:

Tuesday, 6 December, 2022 12:56 PM
Tuesday, 13 December, 2022 12:56 PM
