A stack is a data structure that allows adding elements to the top of the stack through a Push operation, or removing elements from the top of the stack through a Pop operation.
The .NET Framework includes a Stack<T> type, defined in System.Collections.Generic, that implements a stack data type.
When you declare a stack, you indicate the type of objects that the stack will contain.
1 | Stack<Book> pileOfBooks = new Stack<Book>(); |
You can now add instances of Books to the top of the stack using the Push method.
1 2 3 4 5 | // Push 1st book onto stack<span class="skimlinks-unlinked">pileOfBooks.Push(new</span> Book("The World According to Garp", new Person("Irving", "John")));// Push another. Gatsby on "top" of stack<span class="skimlinks-unlinked">pileOfBooks.Push(new</span> Book("The Great Gatsby", new Person("Fitzgerald", "F. Scott"))); |
You can remove the object from the stop of the stack using the Pop method.
1 2 3 | // Remove book from topBook bookToRead = <span class="skimlinks-unlinked">pileOfBooks.Pop</span>();Console.WriteLine(bookToRead); |
