使用Push操作设置堆栈以将元素添加到堆栈-
Stack st = new Stack(); st.Push('A'); st.Push('M'); st.Push('G'); st.Push('W');
要从堆栈中弹出元素,请使用Pop()
方法-
st.Pop();
st.Pop();
以下是使用Push和Pop操作实现堆栈的示例-
例
using System; using System.Collections; namespace CollectionsApplication { class Program { static void Main(string[] args) { Stack st = new Stack(); st.Push('A'); st.Push('M'); st.Push('G'); st.Push('W'); Console.WriteLine("Current stack: "); foreach (char c in st) { Console.Write(c + " "); } Console.WriteLine(); st.Push('V'); st.Push('H'); Console.WriteLine("The next poppable value in stack: {0}", st.Peek()); Console.WriteLine("Current stack: "); foreach (char c in st) { Console.Write(c + " "); } Console.WriteLine(); Console.WriteLine("Removing values "); st.Pop(); st.Pop(); st.Pop(); Console.WriteLine("Current stack: "); foreach (char c in st) { Console.Write(c + " "); } } } }
输出结果
Current stack: W G M A The next poppable value in stack: H Current stack: H V W G M A Removing values Current stack: G M A
