The syntax for a foreach loop is the following.

foreach(data_type var_name in collection) {

}

so in your example, lets say your phonebook array contained integers representing the digits of a phonenumber. ex: {5551055, 1112222, 4443333}

int[] phonebook = {5551000,1112222,4443333};
foreach(int number in phonebook){
Console.WriteLine(number);
}

This code would print all numbers in the phonebook array to the console.
