1. List

List有ArrayList和LinkedList

• ArrayList 類似數組，查找快，插入刪除慢(相對)
• LinkedList 類似雙向鏈表，查找慢(相對)，插入刪除快

//ArrayList

//ArrayList
ArrayList arrList = new ArrayList();
arrList.Add("andy");
arrList.Add("sandy");
arrList.Add("sunny");arrList.RemoveAt(1);arrList.Reverse();arrList.Insert(1, "tom");arrList.InsertRange(0, new[] {"times","jerry"});foreach (var item in arrList)
{Console.WriteLine(item);
}/*timesjerrysunnytomandy*/

//LinkList

//LinkList
LinkedList<string> linkArr = new LinkedList<string>();
//從頭部加入
linkArr.AddFirst("andy");
linkArr.AddFirst("sandy");
linkArr.AddFirst("sunny");
//sunny
//sandy
//andy
//從尾部加入
linkArr.AddLast("tom");
linkArr.AddLast("jerry");
/*
sunny
sandy
andy
tom
jerry
*///在順數第三個位置添加元素
linkArr.AddAfter(linkArr.First.Next, "get");
//在倒數第三個位置添加元素
linkArr.AddBefore(linkArr.Last.Previous, "give");foreach (var item in linkArr)
{Console.WriteLine(item);
}/*
sunny
sandy
get
andy
give
tom
jerry
*/

2. Queue

隊列，先進先出

Queue<string> queue = new Queue<string>();
queue.Enqueue("tom");
queue.Enqueue("jerry");
queue.Enqueue("times");string deTemp = queue.Dequeue();
Console.WriteLine("dequeue ele is "+deTemp);
Console.WriteLine(queue.Count);
Console.WriteLine(queue.Contains("tom"));
//給容器瘦身
queue.TrimExcess();string[] strArr = queue.ToArray();foreach (var item in strArr)
{Console.WriteLine(item);
}
/*dequeue ele is tom2Falsejerrytimes*/
