How do I generate date for each day in the next week

Add the following class to your project.

public static class DateTimeHelpers  
{  
    public static DateTime Next(this DateTime from, DayOfWeek dayOfWeek)  
    {  
        int start = (int)from.DayOfWeek;  
        int target = (int)dayOfWeek;  
        if (target <= start)  
        {  
            target += 7;  
        }  
  
        return from.AddDays(target - start);  
    }  
  
    public static List<DateTime> NextWeeksDates() =>  
        Enumerable.Range(0, 7).Select(index =>   
            DateTime.Now.Next(DayOfWeek.Sunday).AddDays(index)).ToList();  
}  

Get dates

foreach (var dateTime in DateTimeHelpers.NextWeeksDates())  
{  
    Console.WriteLine(dateTime.ToShortDateString());  
}  

Hi MohammedFaraj, guess this is what you ask for.

Today is 8/19/2022 and with the code below, you can generate the date for each day in the next week:

            string NextSun = DateTime.Now.AddDays(0 - Convert.ToInt16(DateTime.Now.DayOfWeek) + 7).ToString();  
            string NextMon = DateTime.Now.AddDays(1 - Convert.ToInt16(DateTime.Now.DayOfWeek) + 7).ToString();  
            string NextTue = DateTime.Now.AddDays(2 - Convert.ToInt16(DateTime.Now.DayOfWeek) + 7).ToString();  
            string NextWed = DateTime.Now.AddDays(3 - Convert.ToInt16(DateTime.Now.DayOfWeek) + 7).ToString();  
            string NextThu = DateTime.Now.AddDays(4 - Convert.ToInt16(DateTime.Now.DayOfWeek) + 7).ToString();  
            string NextFri = DateTime.Now.AddDays(5 - Convert.ToInt16(DateTime.Now.DayOfWeek) + 7).ToString();  
            string NextSat = DateTime.Now.AddDays(6 - Convert.ToInt16(DateTime.Now.DayOfWeek) + 7).ToString();  
  
            Console.WriteLine(NextSun);  
            Console.WriteLine(NextMon);  
            Console.WriteLine(NextTue);  
            Console.WriteLine(NextWed);  
            Console.WriteLine(NextThu);  
            Console.WriteLine(NextFri);  
            Console.WriteLine(NextSat);  

Just copy the code to your project and you can see the result below:
