I got an array of days, have to select next upcoming day by comparing today,
here is my code snippet-

private string GetUpcomingDeliveryDay(string today, ModelSetting ObjModelSetting)

 //string today = DateTime.Now.DayOfWeek.ToString(); //Tuesday
 // daysOfDeliveries = ("Monday","Friday")
 string daysOfDeliveries = Convert.ToString(ObjModelSetting.DeliveryDays).Split(',');
 string nextDelivery = string.Empty;

 return nextDelivery;

ex. if today is Monday and it is present in the array then it should return Monday else upcoming closest day from that array.

I never worked on days and date section before so it's getting harder for me.
thank you!

If you have daysOfDeliveries in DaysOfWeek format then it will be easy. So if it is in string format first you need to convert it to Enum.DaysOfWeek. The rest will be a simple comparison:

var days = daysOfDeliveries.Select(x => (DayOfWeek)Enum.Parse(typeof(DayOfWeek), x)).ToArray();
DayOfWeek today = DateTime.Now.DayOfWeek;
var nextDelivery = days.Where(x => x >= today).FirstOrDefault();

please make sure that the strings in daysOfDeliveries comply with the Enum names.

You can try something like this:

private static string GetUpcomingDeliveryDay(string today, string days) 

 if (days.Length == 0)
 
 return string.Empty; 
 

 if (days.Any(x => x == today.ToString())) 
 
 return today; 
 

 var day = string.Empty;
 var allDays = Enum.GetValues(typeof(DayOfWeek));
 var i = Array.IndexOf(allDays, Enum.Parse(typeof(DayOfWeek), today));

 while (string.IsNullOrEmpty(day))
 
 i++;

 if (i >= allDays.Length) 
 
 i = 0; 
 

 if (days.Any(x => x == allDays.GetValue(i).ToString()))
 
 day = allDays.GetValue(i).ToString();
 
 

 return day;
