动态数组

using System.Collections;
using System.Text.RegularExpressions;
namespace demo1
{/// <summary>/// 常用的集合类型有动态数组（ArrayList类）、堆栈（Stack类）、Queue类和Hashtable类/// </summary>internal class progrm{static void Main(string[] args){//动态数组元素的添加//创建一个arraylist实例，大小为5ArrayList array = new ArrayList(5);Console.WriteLine("arraylist中包含的元素个数{0}", array.Count);array.Add(100);//添加一个整数类型array.Add("i love you");Console.WriteLine("arraylist中包含的元素个数{0}",array.Count);string[] s1 = { "孙", "李", "王" };array.AddRange(s1);//遍历foreach (object i in array){Console.WriteLine("array内的元素{0}",i);        }//删除元素array.RemoveRange(0,1);foreach (object i in array){Console.WriteLine("array内的元素{0}", i);}}}

堆栈

using System.Collections;
namespace demo1
{/// <summary>/// 堆栈后进先出的对象集合/// </summary>internal class progrm{        static void Main(string[] args){Stack stack = new Stack(); //实例化一个对象Console.WriteLine("向堆栈的顶部添加四个对象");stack.Push('a');stack.Push('b');stack.Push('c');stack.Push('d');Console.WriteLine(stack.Count);foreach (object item in stack){Console.WriteLine(item);}Console.WriteLine("向堆栈的顶部添加2个对象");stack.Push('e');stack.Push("f");foreach (object item in stack){Console.WriteLine(item);}Console.WriteLine("堆栈顶部的对象{0}",stack.Peek());Console.WriteLine("移除堆栈顶部的对象{0}",stack.Pop());Console.WriteLine("遍历堆栈");foreach (object item in stack){Console.WriteLine(item);}}}

队列

using System.Collections;

哈希表

using System.Collections;
namespace demo1
