下面介紹C#的集合類
1ArrayList
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Collections;
namespace 動態數組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("遍歷方法1:");
foreach (int i in a1)
{
Console.WriteLine(i);
}
Console.WriteLine("遍歷方法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集合類
{
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("出棧");
foreach (int i in s1)
{
Console.WriteLine(i);
}
int num=(int)s2.Peek();
Console.WriteLine("彈出最后一項{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集合類
{
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出隊");
foreach (int i in q1)
{
Console.WriteLine(i);
}
int num=(int)q2.Peek();
Console.WriteLine("取q2開始處{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集合類
{
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集合類
{
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();
}
}
}
