集群

1. 线性群集
2. 非线性群集

线性群集

• 直接存取群集（数组，字符串，结构）ArrayList，StringBuild，Struct
• 顺序存取群集（栈，队列）Stack，Queue
• 索引群集（散列表，字典）Hashtable，Directionary

非线性群集

• 层次群集（树-二叉树，堆）
• 组群集（集合，图，网络）

 

通过CollectionBase类实现Collection类

class Collection:CollectionBase
    {
        public void Add(object item)
        {
            InnerList.Add(item);
        }

        public void Remove(object item)
        {
            InnerList.Remove(item);
        }


        public int Count(object item)
        {
            return InnerList.Count;
        }

    }

泛型编程

 class Nodes<T>
    {
        T data;
        Nodes<T> Link;
        public Nodes(T data,Nodes<T> Link)
        {
            this.data = data;
            this.Link = Link;
        }
    }
     static void Swap<T>(ref T a, ref T b)
        {
            T temp;
            temp = a;
            a = b;
            b = temp;
        }

 

程序运行时间测试类

class Timing
    {
       
        TimeSpan duration;

        public Timing()
        {
            duration = new TimeSpan(0);
        }


        public void StopTime()
        {
            duration = Process.GetCurrentProcess().TotalProcessorTime;
        }

        public void StartTime()
        {
            GC.Collect();
            GC.WaitForFullGCApproach();
        }

        public TimeSpan Result()
        {
            return duration;
        }
    }

 

 class Program
    {
        static void Main(string[] args)
        {
            int[] nums=new int[100000];
            BuildArray(nums);
            TimeSpan duration;
            Timing t=new Timing();
            t.StartTime();
            DisplayNums(nums);
            t.StopTime();
            Console.WriteLine("time:"+t.Result().TotalSeconds);
            Console.ReadKey();
           
        }

        static void DisplayNums(int[] args)
        {
            int a = args.GetUpperBound(0);
            for (int i = 0; i < args.GetUpperBound(0); i++)
            {
                ;
            }
        }
        static void BuildArray(int[] args)
        {
            for (int i = 0; i <= 99999; i++)
            {
                args[i] = i;
            }
        }

    }
