Passing user input through a class and displaying it in the console

I am trying to create a C# console app, where if a user presses a number it will ask them to add a task, view current task, delete a task. I have created my first class to "Add a task" just get the user input, and then in the main method call that class running the user input through it, any advice?

class addTask
{
    public string UserInput { get; set; }
    public override string ToString() => UserInput;
}
...
System.Console.WriteLine("Please select what you would like to do");
System.Console.WriteLine("1. Add A Task");
System.Console.WriteLine("2. Remove A Task");
System.Console.WriteLine("3. Update A Task");
System.Console.WriteLine("4. View Task");
int num = Convert.ToInt32(Console.ReadLine());

if (num == 1)
{
    System.Console.WriteLine("Please enter a new Task");
    string input = Console.ReadLine();

    while (input != Console.ReadLine())
    {
        //  a.getUserInput.ToString();
        System.Console.WriteLine($"New Task: {a}");
        break;
    }
}
Console.ReadKey();

To have this output:

You can use this:

using System;
using System.Collections.ObjectModel;

namespace C_TaskManager
{
    public class UserTask
    {
        public UserTask(string Description)
        {
            this.UserInput = Description;
        }
        public string UserInput { get; set; }
        public override string ToString()
        {
            return UserInput;
        }
    }
    public class TaskManager
    {
        public ObservableCollection<UserTask> UserTasks { get; set; } = new ObservableCollection<UserTask>();
    }
}
