The foreach statement is used to iterate through a collection which implements the IEnumerable or IEnumerable interface without having to specify the index of each element. This includes arrays and lists amongst other collections. However it can't be used to add or remove elements to or from the collection. You need to use an ordinary 'for' loop for this.
