Program

DateTime dtBirthDate = new DateTime(1971, 2, 23);

DateTime dtBirthDate = new DateTime(1971, 2, 23);

Student

public DateTime DateOfTime { get; set; }

        public int GetAge()
        {
            var today = DateTime.Now;

            var age = today.Year - DateOfTime;

            if (DateOfTime.Date > today.AddYears(-age)) age--;

            return age;
        }

public DateTime DateOfTime { get; set; }

        public int GetAge()
        {
            var today = DateTime.Now;

            var age = today.Year - DateOfTime;

            if (DateOfTime.Date > today.AddYears(-age)) age--;

            return age;
        }

I am trying to calculate the age, from the birthdate to now. but I am not sure how to do it when using properties

should DateOfTime not be DateOfBirth? except it's not. a datetime minus a datetime results in a timespan how stupid 'TimeSpan' does not contain a definition for 'TotalYears'

Ah okay thanks, if I get it as days I can just devide it by 365 and by doing that get the years

        public int Age
        {
            get { 

                var today = DateTime.Today;
                var age = DateOfTime - today;
                age = Convert.ToInt32(ToString());
                return _Age; }

            set { _Age = value; }
        }

        public int Age
        {
            get { 

                var today = DateTime.Today;
                var age = DateOfTime - today;
                age = Convert.ToInt32(ToString());
                return _Age; }

            set { _Age = value; }
        }

This is correct right? I am trying to converting it to a string? Whops catlaugh

It's fixed now, thanks for the help

        public int Age
        {
            get { 

                var today = DateTime.Today;
                double antalDage = (DateOfTime - today).TotalDays;
                int age = (int)antalDage / 365;
                return _Age; }

            set { _Age = value; }
        }

        public int Age
        {
            get { 

                var today = DateTime.Today;
                double antalDage = (DateOfTime - today).TotalDays;
                int age = (int)antalDage / 365;
                return _Age; }

            set { _Age = value; }
        }

Thanks again catlaugh

        public int Age
        {
            get { 

                double antalDage = (DateOfTime - DateTime.Now).TotalDays;
                int _Age = (int)antalDage / 365;
                return _Age; }

            set { _Age = value; }
        }

        public int Age
        {
            get { 

                double antalDage = (DateOfTime - DateTime.Now).TotalDays;
                int _Age = (int)antalDage / 365;
                return _Age; }

            set { _Age = value; }
        }

But I get -51 for some reason That is werid

ero•2y ago

I feel like there shouldn't be a set You can't set the age of a person You can't set their date of birth either

DayKnight•2y ago

It's fixed now, now it says +51 instead Remove set? Hmm, it does seem kinda useless here, that is true
