If int value equal to x replace with a string

Question

I am storing a int in schadstoffklasse so when calling the Car object like so (last int in brackets) : PKW Kaefer = new PKW("VW", "Käfer", "K-GS-01", 1965, 9999, 1000, 30, 1); I can either say 0, 1, 2. Now when i write this Console.WriteLine(Kaefer.Schadstoffklasse) to the console it obiously outputs 1 in this case.

I do want it to not say 1 i want for example....

0 = foo 1 = bar 2 = foobar

So it outputs to the console a string.

Here is what i have tried, which does not work.

private int schadstoffklasse;

    public int Schadstoffklasse
    {
        get
        {
            return schadstoffklasse;
        }
        set
        {
            if (value == 0)
            {
                string foo = value.ToString();
                foo = "BLABLALBA";

            }

            schadstoffklasse = value;
        }
    }

Thank you for having patience with a beginner

Answer 1

You can't have a property return mixed types. Your property of Schadstoffklasse is an int, therefore it can only ever return an int never a string.

There are a variety of different ways to accomplish this though, but without knowing more of how you are using this it'd be impossible to say which one you should do. I'd recommend either another property that has no setter and the getter looks at the other property, reads it's value and returns the string that you want or a method that does the same.

To expand on my suggestion:

public enum SchadstofklasseStrings
{
    foo = 0,
    bar = 1,
    foobar = 2
}

public int Schadstoffklasse { get; set; }
public string SchadstoffklasseToString { 
{
    get
    {
        var stringValue = (SchadstofklasseStrings) Schadstoffklasse;
        return stringValue.ToString();
     }
}

Also, sorry for mutilating the German.
