Collection類學習

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Collections;namespace Colloction{    class Collection:CollectionBase    {        public void Add(Object item) { InnerList.Add(item); }        public void Remove(Object item) { InnerList.Remove(item); }        public void Clear(){InnerList.Clear();}        public int Count() { return InnerList.Count; }            }    class Program    {        static void Main(string[] args)        {            Collection names = new Collection();            names.Add("1");            names.Add("2");            names.Add("3");            names.Add("4");            foreach (Object name in names) { Console.WriteLine(name); }            Console.WriteLine("總數量: "+names.Count());            names.Remove("3");            Console.WriteLine("總數量: " + names.Count());            names.Clear();            Console.WriteLine("總數量: " + names.Count());                    }    }}

 泛型

 static void Swap<T>(ref T val1,ref T val2)        {            T temp;            temp = val1;            val1 = val2;            val2 = temp;        }        static void Main(string[] args)        {            int num1 = 100;            int num2 = 200;            Swap<int>(ref num1, ref num2);            Console.WriteLine(num1);        }

 測量時間

            DateTime startTime;            TimeSpan endTime;            startTime = DateTime.Now;            for (int i = 0; i < 10000000; i++)                ;            endTime = DateTime.Now.Subtract(startTime);            Console.WriteLine(endTime.TotalSeconds);
