Retrieve bool result by using LinQ code

Question

If the ingredients of a pizza exist among allIngred, the result would give true by using LINQ. How would I go about doing this?

string[] allIngred = {
    "oil", "yeast", "wheat-flour", "salt", "oil", "baking-powder",
    "wheat-flour", "salt", "sugar", "milk"
};
string[] pizza = { "oil", "yeast", "wheat-flour", "salt" };

Answer 1

You can use a combination of the All and Contains methods to check that all items in pizza exist in allIngred:

bool result = pizza.All(i => allIngred.Contains(i));
