Question

This one has me stumped, since I don’t think this can be done with a simple DateTime method, unless there’s something I’m not understanding.

It should be simple like this: format the variables to read in the XX/XX/XXXX format and if one of these integers is 0, a console output should read ~~unspecified~~

   namespace TheTime
    {
        public class Time
        {
            private int month;
            private int day;
            private int year;

            public int Mont{}
            public int Day {}
            public int Year {}

Answer 1

Add this method to your Time class.

public string FormattedDate()
{
    if (month == 0 || day == 0 || year == 0)
        return string.empty;

    DateTime dt = new DateTime(year, month, day);
    return dt.ToString("d"); // returns mm/dd/yyyy
}

Then to use it:

string sDate = myTimeObj.FormattedDate();

if(sDate == string.empty)
{
   Console.WriteLine("~~unspecified~~");
}
else
{
   // it worked fine
}
