Question

I cannot return from a ForEach, here is my code:

cards.ForEach(delegate(Card c){
    if (c.GetFaceValue().ToString() == card) {
        return "Your Card has been located";
    }

error:

Cannot convert anonymous method to delegate type ‘… .Card>’ because some of the return types in the block are not implicitly convertible to the delegate return type

the following wont work either, as CheckCard can only return void:

 cards.ForEach(CheckCard);

 public string CheckCard(Card c) {
        if (c.GetFaceValue().ToString() == card) { // card = global 
            return "Your Card has been located";
        }
    }

error:

‘string SharedGamesClasses.Hand.CheckCard(SharedGamesClasses.Card)’ has the wrong return type

Answer 1

You’re currently trying to return a message from the anonymous function and not your calling code; that won’t work as the anonymous function is an Action<T>, which can’t return anything.

Do you just want to see if any element in cards matches card and return the message if so?

Use .Any() instead of .ForEach():

if (cards.Any(c => c.GetFaceValue().ToString() == card))
{
    return "Your Card has been located";
}
