how do i store a string value from user input in a list using loop for multiple entry c#
Question
Write a program to do the following: Create a console application which asks user to enter suburb and postcode for two cities Auckland and Wellington. Iterate this 10 times (which means the user has to input suburb and postcode, one after the other 10 times). You are required to handle the exceptions using try and catch block. Store the values of suburb in a List called suburb_values and the values of the postcodes in a List called postcode_values. You are now required to ask the user if they want to INSERT(), REMOVE() or CONTAINS(). This must be a switch case. If the user selects 1: you are required to INSERT 5 pre-defined suburb and post code values into the respective lists and print the final values inside the list. If the user selects 2: you are required to REMOVE 4 values using Remove() and RemoveAt(). If the user selects 3: you are required to check if the suburb_values list contains atleast 5 suburbs that the user will enter. If the user selects any other value: you need to display invalid and exit.
THIS IS MY CODE TILL NOW
using System;
using System.Collections.Generic; // TO HAVE LIST YOU NEED TO ADD THIS LINE using System.Collections.Generic; UNDER the line using System;
namespace Assessent1ListUsingGenerics
{
class Program //List<T> in C# | In Class Activity
{ //a. WAP to insert 10 values of Country and capital names and
//its pin code (two lists: suburb<string> and pincode<int>).
//Print and display the list.
static void Main(string[] args)
{
int counter = 0;
var suburb_values = new List<string>();
while (counter < 10)
{
//creating list suburb_ values ( String Type )
//Adding values to the list from user input //user input will be saved in country_values
Console.WriteLine("PLease Enter a Suburb for Auckland City");
suburb_values.Add(Console.ReadLine()); //suburb_values 1 //this will be the index 2 correct ?
suburb_values.Add(Console.ReadLine()); //suburb_values 2
suburb_values.Add(Console.ReadLine()); //suburb_values 3 country_values.Add(Console.ReadLine()); //country name 1
suburb_values.Add(Console.ReadLine()); //suburb_values 4
suburb_values.Add(Console.ReadLine()); //suburb_values 5

suburb_values.Add(Console.ReadLine()); //suburb_values 9
suburb_values.Add(Console.ReadLine()); //suburb_values 10
counter;
}
//creating list postcode_values ( String Type )
var postcode_values = new List<string>();
Console.WriteLine("Please enter a Post code for the Auckland Suburb you entered ");
//Adding values to the list
postcode_values.Add(Console.ReadLine()); //postcode 1
postcode_values.Add(Console.ReadLine()); //postcode 2

postcode_values.Add(Console.ReadLine()); //postcode 8
postcode_values.Add(Console.ReadLine()); //postcode 9
postcode_values.Add(Console.ReadLine()); //postcode 10
Console.WriteLine("PLEASE CHOOSE TO INSERT - REMOVE _ CONTAINS \n");
Console.WriteLine("PLEASE SELECT ON OPTION: ");
Console.WriteLine("\nPress 1 for Insert - Press 2 for Remove - Press 3 for Contains ");
int userInput = Convert.ToInt32(Console.ReadLine()); //ASK YOUR INPUT WITH THIS CODE, what user type will be saved inside userInput
switch (userInput)
{
case 1: //you are required to INSERT 5 pre-defined suburb and post code values into the respective lists and print the final values inside the list. ");
{
Console.WriteLine("\nOption 1 Selected - PLEASE INSERT 2 SUBURBS AND 2 POSTCODES FOR AUCKLAND CITY");
//Inserting values to the Suburb list
Console.WriteLine("Please Insert a Suburb ");
suburb_values.Insert(0, Console.ReadLine());
Console.WriteLine("Please Insert the next Suburb ");
suburb_values.Insert(1, Console.ReadLine());
//inserting values to the PostCode list
Console.WriteLine("Please Inser a PostCode");
postcode_values.Insert(0, Console.ReadLine());
Console.WriteLine("Please Inser a PostCode");
postcode_values.Insert(1, Console.ReadLine());
break;
}
case 2:
{
Console.WriteLine("\nOption 2 selected - you are required to REMOVE 4 values using Remove() and RemoveAt().D");
suburb_values.Remove("");
suburb_values.RemoveAt(0);
break;
}
case 3:
{
Console.WriteLine(" you are required to check if the suburb_values list contains atleast 5 suburbs that the user will enter. ");
// code to check missing
break;
}
default:
Console.WriteLine("Invalid");
break;
}
Console.ReadKey();
}

At this stage i have the code almost done but how do I check if the suburb_values list contains atleast 5 suburbs that the user will enter. ???
here is my code updated still not sure if is 100% correct but I'm trying
using System; using System.Collections.Generic; // TO HAVE LIST YOU NEED TO ADD THIS LINE using System.Collections.Generic; UNDER the line using System;
namespace Assessent1ListUsingGenerics {
class Program //List in C# |
{ //a. insert 10 values of suburb_values and postcode_values
static void Main(string[] args)
{ //------------------------------------ AUCKLAND---------------------------------------------------------------
int counter = 0; // this is for the loop to execute asking user input 10x times for each suburb and postcode values to store in the variables
var suburb_values = new List<string>(); //creating list suburb_ values ( String Type )
var postcode_values = new List<string>(); //creating list postcode_values ( String Type )
try
{
while (counter < 10) //counter is zero and won't pass the limit of 10 times if the user input some value
{
//Adding values to the list from user input //user input will be saved in suburb_values
Console.WriteLine("Please enter a Suburb for Auckland City: ");
suburb_values.Add(Console.ReadLine()); //suburb_values 1 //this will be the index 2 correct ?
//Console.Clear();
Console.WriteLine("Please enter a Post code number: ");
//Adding values to the list
postcode_values.Add(Console.ReadLine()); //postcode 1
// Console.Clear();
counter++;
}
}
catch (FormatException e)
{
Console.WriteLine(e.Message);
}
finally
{
Console.WriteLine(""); //This is Finally block and get executed regardless
}
//--------------FROM HERE SWITCH LOOP FOR AUCKLAND-------------------------------------------------------
