1ArrayList
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Collections; namespace 动态数组ArrayList { class Program { static void Main(string[] args) { ArrayList a1 = new ArrayList(); a1.Add(100); foreach (int number in new int[6] { 9, 3, 7, 2, 4, 8 }) { a1.Add(number); } int[] number2 = new int[2] { 11, 12 }; a1.AddRange(number2); a1.Remove(3); a1.RemoveAt(3); ArrayList al2 = new ArrayList(a1.GetRange(1,3)); Console.WriteLine("遍历方法1:"); foreach (int i in a1) { Console.WriteLine(i); } Console.WriteLine("遍历方法2:"); for (int i = 0; i < al2.Count; i++) { Console.WriteLine(al2[i]); } Console.ReadLine(); } } }
2 Stack
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Collections; namespace Stack集合类 { class Program { static void Main(string[] args) { Stack s1 = new Stack(); Stack s2 = new Stack(); foreach (int i in new int[4] { 1, 2, 3, 4 }) { s1.Push(i); s2.Push(i); } foreach (int i in s1) { Console.WriteLine(i); } s1.Pop(); Console.WriteLine("出栈"); foreach (int i in s1) { Console.WriteLine(i); } int num=(int)s2.Peek(); Console.WriteLine("弹出最后一项{0}",num); foreach (int i in s2) { Console.WriteLine(i); } Console.ReadLine(); } } }
3Queue
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Collections; namespace Queue集合类 { class Program { static void Main(string[] args) { Queue q1 = new Queue(); Queue q2 = new Queue(); foreach(int i in new int [4]{1,2,3,4}) { q1.Enqueue(i); q2.Enqueue(i); } foreach (int i in q1) { Console.WriteLine(i); } q1.Dequeue(); Console.WriteLine("q1出队"); foreach (int i in q1) { Console.WriteLine(i); } int num=(int)q2.Peek(); Console.WriteLine("取q2开始处{0}",num); foreach(int i in q2) { Console.WriteLine(i); } Console.ReadLine(); } } }
4Hashtable
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Collections; namespace Hashtable集合类 { class Program { static void Main(string[] args) { Hashtable h = new Hashtable(); h.Add("E","e"); h.Add("B", "b"); h.Add("C", "c"); h.Add("A", "a"); foreach (DictionaryEntry e in h) { Console.Write("{0},{1} ", e.Key, e.Value); } Console.WriteLine(); string s = (string)h["C"]; Console.WriteLine(s); if (h.Contains("E")) { Console.WriteLine("含有E"); } Console.WriteLine(h["A"]); h.Remove(h["A"]); h.Clear(); foreach (DictionaryEntry e in h) { Console.Write("{0},{1} ", e.Key, e.Value); } Console.ReadLine(); } } }
5SortedList
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Collections; namespace SortedList集合类 { class Program { static void Main(string[] args) { SortedList s1 = new SortedList(); s1["c"]=41; s1["a"]=42; s1["d"]=11; s1["b"]=13; foreach (DictionaryEntry e in s1) { string s = (string)e.Key; int i = (int)e.Value; Console.Write("{0},{1} ",s,i); } Console.ReadLine(); } } }
