Two classes how to properly return values from class A to B

I have two classes. First class takes user input as a string. User can choose for example: bananas, apples, grapes and blueberries.

class Choice
{
    string fruit;
    public void ChooseFruit()
    {
        Console.WriteLine("Enter [bananas] or [apples] or [grapes] or [bluebarries]");
        fruit = Console.ReadLine();
        ...
    }
}

Second class stores a variables for every fruit for examples if its banana (amount = 102.4, price = 12.34, volume = 16.3) different variables for every fruit.

How to return all the variables (amount, price, volume) to the first class for a chosen fruit in a proper way ?

[EDIT] I tried something like this (it works but it doesnt look right): 

class Choice
{
    string fruitName;
    float amount, price, volume;
    public void ChooseFruit()
    {
        Console.WriteLine("Enter [bananas] or [apples] or [grapes] or [bluebarries]");
        string fruitName = Console.ReadLine();

        Fruit f1 = new Fruit(fruitName);
        amount = f1.Amount;
        price = f1.Price;
        volume = f1.Volume;
        //...................//
    }
}
class Fruit
{
    public float Amount { get; private set; }
    public float Volume { get; private set; }
    public float Price { get; private set; }

    public Fruit(string name)
    {
        if (name.ToLower() == "bananas")
        {
            Amount = 12;
            Volume = 1.6f;
            Price = 27;
        }
        else if (name.ToLower() == "grapes")
        {
            Amount = 12;
            Volume = 1.6f;
            Price = 27;
        }
        // AND OTHERS //
    }
}

It appears that you want the community to solve your school assignments?

Anyway - try and have a look at

Inheritance C#

or even better

Polymorphism

.. and see if you can make sense of it.

Good luck /Anders

Here's a quick implementation:

public enum Fruits {
    Bananas,
    Apples,
    Grapes,
    Blueberries
}

public class FruitInfo
{       
    public Fruits Fruit { get; }
    public decimal Price {get; set}
    ...   
}

// TODO: Populate this dictionary with all your fruit info
private Dictionary<Fruits , FruitInfo> _fruitDatabase;

public FruitInfo ChooseFruit()
{
    while(true)
    {
        Console.WriteLine("Choose [bananas], [apples], [grapes], or [blueberries]: ");
        var input = Console.ReadLine();
        Fruits selection;

        if(!Enum<Fruits>.TryParse(input, true, out selection))
        {
            Console.Error.WriteLine("Invalid Fruit Selection, Try Again.");
            continue;
        }

        return _fruitDatabase[selection];
    }
}
