I want to get multiple string values(selectedNameand selectedCurrency) individually from public override string ToString() below. How do I go on about it?

 using System.Collections;
       using System.Collections.Generic;
       using UnityEngine;  

       [CreateAssetMenu(fileName = "Country", menuName = "Country/Country", order = 0)]
       public class country : ScriptableObject
       {
           [System.Serializable]
           public class Item
           {
               public string Name;
               public string Currency;
               public string Capital;
               public string[] City;

    public override string ToString()
    {
    string selectedName = this.name;
    string selectedCurrency = this.currency;
    return selectedName + selectedCurrency; 
    }

           }

           public Item[] m_Items;
       public Item PickRandomly()
    {
        int index = Random.Range(0, m_Items.Length);
        return m_Items[index];
    }
}

I need to use the selected string values in the script below.

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using UnityEngine.UI;

    public class GameController: MonoBehaviour
    {   public country country; //This is the scriptable object country
    public Text countryText;
    public Text currencyText;

    void Start(){
    countryText.text = country.PickRandomly().ToString(); // This is where I need the country name string to show up.
currencyText.text = country.PickRandomly().ToString(); // This is where I need the currency string to show up.
    }
    }

Right now it just displays a random country name and currency for example USA USD in both the fields.

You could make it return an array and select what you need.
Code:

public override string ToString()
{
	string selectedName = this.name;
	string selectedCurrency = this.currency;
	return {selectedName, selectedCurrency}; // Return an array
}

countryText.text = country.PickRandomly().ToString()[0]; // To select the first item in the array

Or pass an argument to ToString so it returns what you need.

public override string ToString (string whatToReturn)
{
	if (whatToReturn == "name") {
		return this.name;
	}

	if (whatToReturn == "currency") {
		return this.currency;
	}
}

countryText.text = country.PickRandomly().ToString("name");
