C#集合类用法实例代码详解

下面介绍c#的集合类

1arraylist

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();
    }
  }
}
