How can i repeat the condition if the user wants to input many student name in the list and how can i list all of them. after i input "N"

Question

I only got the example of the program but how can i repeat the condition in order to get the desired output of the program. I'm confused on how I'm going to repeat the condition to add number in the "INSERT STUDENT {0}" what if the users want to insert more than 10 student name.

here's is what i have started:

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

        string insertStudentOne = "INSERT STUDENT 1:";
        string insertStudentTwo = "INSERT STUDENT 2:";
        string listOfStudent = "List of Student:";

        string studentOne;
        string studentTwo;

        Console.Write(insertStudentOne);
        studentOne = Console.ReadLine();
        studentName.Add(studentOne);

        Console.Write(insertStudentTwo);
        studentTwo = Console.ReadLine();
        studentName.Add(studentTwo);

        string selectAnswer = "DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?: ";
        string answerStr;
        Console.Write(selectAnswer);
        answerStr = Console.ReadLine();
        string name;

        if (answerStr.Equals("Y"))
        {
            {
                int addedStudent = 2;
                int sum;
                sum = addedStudent + 1;
                Console.Write("INSERTE STUDENT {0}: ", sum);
                name = Console.ReadLine();
            }

            Console.Write("DO YOU WANT TO CONTINUE ADDING STUDENT(Y / N) ?: ");
             string addedStudent1= Console.ReadLine();
            studentName.Add(addedStudent1);

            if (addedStudent1.Equals("N"))
            {
                Console.WriteLine(listOfStudent);
                Console.WriteLine(studentOne);
                Console.WriteLine(studentTwo);
                Console.WriteLine(name);

            }
            Console.ReadKey(); 

The sample program output should be like this:

INSERT STUDENT 1: JAMES INSERT STUDENT 2: JOHN DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?:Y INSERT STUDENT 3: MICHAEL DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?:N LIST OF STUDENTS: JAMES JOHN MICHAEL

INSERT STUDENT 1: JAMES INSERT STUDENT 2: JOHN DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?:N LIST OF STUDENTS: JAMES JOHN

INSERT STUDENT 1: JAMES INSERT STUDENT 2: JOHN DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?:Y INSERT STUDENT 3: MICHAEL DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?:Y INSERT STUDENT 4: WILLIAM DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?:Y INSERT STUDENT 5: JORDAN DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?:N LIST OF STUDENTS: JAMES JOHN MICHAEL WILLIAM JORDAN

As you can see the "INSERT STUDENT {0} "added +1 after the "INSERT STUDENT 2" and everytime the answer is "Y" but if i Input the Letter "N" it will display all the inserted name Like sample program#2 if Input "N" after Student 2 it will display the student quickly and will always ask me if i want to cointinue adding student.However, if i alsways insert "Y" it will not stop to print the student inifinitely until i inserted "N". Some of my friends suggest that use foreach or LINQ to answer this. I'm just beginner in programming i want to learn programming deeper even i did not finish my college. i hope someone knows how to address my question. thanks in advance.

First of all check out arrays or lists which can store many variables. Otherwise you may need to create hundreds of student variables.

You may use a do-while loop to achieve the problem.

string answerStr = "";
do {
    string selectAnswer = "DO YOU WANT TO CONTINUE ADDING STUDENT (Y/N)?: ";
    Console.Write(selectAnswer);
    answerStr = Console.ReadLine();
    // get the user input
    // add the new user to a list or an array
    // then repeat the steps until the user gives an input other then "Y".
} while(answerStr == "Y");
