C#程序通过Push和Pop操作实现堆栈
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
