I am trying to enter input from the console(street, city, country) but the fields are underlined and display the message(field is never assigned to and will have its value null). I have also created a method SetFullAddress which doesn't work(idk if it is because of that message).

Code inside Address class:

```
public class Address
{
    private string street;
    private string city;
    private string country;

    public Address()
    {
        this.Street = street;
        this.City = city;
        this.Country = country;
    }

    public string Street { get; set; }
    public string City { get; set; }
    public string Country { get; set; }

    public string SetFullAddress()
    {
        return ($"Full address: {street} {city} {country}");
    }

    public void DisplayAddress()
    {
        Console.WriteLine($"Street: {Street}");
        Console.WriteLine($"City: {City}");
        Console.WriteLine($"Country: {Country}");
        Console.WriteLine(SetFullAddress());

    }

}

```

And inside Main method:

```
        Address address = new Address();
        Console.Write("Street: ");
        address.Street = Console.ReadLine();

        Console.Write("City: ");
        address.City = Console.ReadLine();

        Console.Write("Country: ");
        address.Country = Console.ReadLine();

        Console.WriteLine();
        address.DisplayAddress();

```
