❔ How to shorten switch statement

        public void SwitchAvailability(string koalaName)
        {
            switch(koalaName)

                    break;

        }

        public void SwitchAvailability(string koalaName)

                    break;
                case "Kiki":
                    KikiAvailable = !KikiAvailable;
                    break;
                case "Katie":
                    KatieAvailable = !KatieAvailable;
                    break;
            };
        }

I feel like a noob again. I can't think of how to remove the switch statement. I think I need either the ref keyword or reflections but not sure which and not sure what to do

Looks like you can't return ref from a switch, annoyingly Do you need however-many separate properties? Do you actually use them as properties?

Matt•2y ago

yes they are required properties since they're bound to UI controls for WPF

canton7•2y ago

You can bind to e.g. dictionary elements in WPF, if that makes life easier <TextBlock Text="{Binding Koalas["Kiki"]}"/>

Matt•2y ago

so I could bind to a dictionary of type string bool and get the bool by string?

canton7•2y ago

It's one option

Matt•2y ago

that might make my life significantly easier actually. I'm not the one working on the front end but I'll put the suggestion forwards

That or something like:

class Koala
{
    public string Name { get; }
    public bool IsAvailable { get; set; }

    public Koala(string name) => Name = name;
}

class KoalaCollection
{
    public Koala Boonie { get; }
    public Koala Mim { get; }

    private readonly Dictionary<string, Koala> koalas = new();

    public KoalaCollection()
    {
        Koala Add(string name)
        {
            var koala = new Koala(name);
            this.koalas[name] = koala;
            return koala;
        }

        Boonie = Add("Boonie");
        Mim = Add("Mim");
    }
 
    public Koala GetByName(string name) => koalas[name];
}

class Koala
{
    public string Name { get; }
    public bool IsAvailable { get; set; }

    public Koala(string name) => Name = name;
}

class KoalaCollection
{
    public Koala Boonie { get; }
    public Koala Mim { get; }

    private readonly Dictionary<string, Koala> koalas = new();

    public KoalaCollection()
    {
        Koala Add(string name)
        {
            var koala = new Koala(name);
            this.koalas[name] = koala;
            return koala;
        }

        Boonie = Add("Boonie");
        Mim = Add("Mim");
    }
 
    public Koala GetByName(string name) => koalas[name];
}

Then "{Binding Koalas.Mim.IsAvailable}" Then you can do:

public void SwitchAvailability(string koalaName)
{
    var koala = koalas.GetByName(koalaName);
    koala.IsAvailable = !koala.IsAvailable;
}

public void SwitchAvailability(string koalaName)
{
    var koala = koalas.GetByName(koalaName);
    koala.IsAvailable = !koala.IsAvailable;
}

(Add INPC as appropriate)
