C＃Foreach循环问题

Question

I was just making this program to experiment with lists and such, and I was curious as to why in the foreach loop the Object always shows up as the "Minecraft" Wish object. Is it because it was the last Wish object to be created? And how can I fix it, so all 3 Wish objects which have been declared show up? Thanks!

        public string getStore()
        {
            return Store;
        }
        public double getCost()
        {
            return ApproxCost;

    }
}

Answer 1

Remove static from Wish members declaration

static means that the data will be shared across all the instances. So static members are also so called class variables. While not static members - are object variables.

Answer 2

这是因为在课堂上希望你将Name，Score和ApproxCost声明为静态。
