Having trouble using the "DateTime" line in VS 2015

 I have everything down except for the DOB. I can't get it to display without the application crashing. The names are and the numbers are but for the DOB I need to use "DateTime".

 

Here's what I have so far, I don't have the DOB stuff entered in anymore because it was causing a crash.

 

 

 

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace MidtermWeek5

{

   class Program

   {

       static void Main(string[] args)

       {

            //VARIABLE AREA

            bool isContinued = true;

            int listCount = 0;

            List<string> firstName = new List<string>();

            List<string> lastName = new List<string>();

            List<int> studentID = new List<int>();

            List<int> classCount = new List<int>();

            List<int> graduateYear = new List<int>();

            while (isContinued)

            {

                 //COLLECT DATA AREA

                 Console.WriteLine("Please enter your first name:");

                 firstName.Add(Console.ReadLine());

                 Console.WriteLine("Please enter your last name:");

                 lastName.Add(Console.ReadLine());

                 Console.WriteLine("Please enter your student ID (XXXX):");

                 studentID.Add(Convert.ToInt32(Console.ReadLine()));

                 Console.WriteLine("Please enter your number of classes:");

                 classCount.Add(Convert.ToInt32(Console.ReadLine()));

                 Console.WriteLine("Please enter your graduation year:");

                 graduateYear.Add(Convert.ToInt32(Console.ReadLine()));

                 //CHECK USER TO CONTINUE

                 Console.WriteLine("Do you want to continue (Y/N)?");

                 if (Console.ReadLine().ToUpper() == "Y")

                 {

                      isContinued = true;

                      Console.Clear(); //clear screen

                 }

                 else

                 {

                      isContinued = false;

                 }

             }

             //DISPLAY RESULTS AREA

             Console.WriteLine("{0, -9} {1, -8} {2, -10} {3, -8} {4, -15}", "First", "Last", "Student ID", "Classes", "Graduate Year");

             Console.WriteLine("-------------------------------------------------------------------------------");

             listCount = firstName.Count;

             while (listCount > 0)

             {

                  Console.WriteLine("{0, -9} {1, -8} {2, -10} {3, -8} {4, -15}", firstName[listCount - 1], lastName[listCount - 1], studentID[listCount - 1], classCount[listCount - 1], graduateYear[listCount - 1]);

listCount--;

             }

             //KEEP THE SCREEN ON

             Console.ReadLine();

          }

      }

}

 

 

 

 

 

 

 

 

I was trying:

 

DateTime birthday;

and 

List birthday = new List();

 

and for collecting the information:

 

Console.WriteLine("Please enter your DOB:");

birthday.Add(Convert.ToDateTime(Console.ReadLine()));

 

and for displaying the information:

 

Console.WriteLine("{0, -9} {1, -8}  {2, -12}  {3, -10} {4, -8} {5, -15}", "First", "Last", "DOB", "Student ID", "Classes", "Graduate Year");

Console.WriteLine("-------------------------------------------------------------------------------");

listCount = firstName.Count;

while (listCount > 0)

{

Console.WriteLine("{0, -9} {1, -8}  {2, -12}  {3, -10} {4, -8} {5, -15}", firstName[listCount - 1], lastName[listCount - 1], birthday[listCount - 1], studentID[listCount - 1], classCount[listCount - 1], graduateYear[listCount - 1]);

listCount--;

}

 

 

Please help!
