几种常用的集合类用法

//列表比较基础就不写了 其他的不太常用

// Dictionary 字典 Dictionary<int, EQInfo> eqs = new Dictionary<int, EQInfo>(); EQInfo tempInfo = new EQInfo(); for (int i = 1; i <= 11; i++) { tempInfo.ID = 1212 * i; tempInfo.buyMoney = 220 * i; tempInfo.sealMoney = 110 * i; eqs.Add(tempInfo.ID, tempInfo); }

EQInfo tempEq; if (eqs.TryGetValue(1212, out tempEq)) { Console.WriteLine(tempEq.buyMoney + " " + tempEq.sealMoney); }var dicSort = from objDic in eqs orderby objDic.Value.buyMoney descending select objDic;

foreach (KeyValuePair<int, EQInfo> item in dicSort) { Console.WriteLine(item.Value.buyMoney); }

 

//字典降序排序方法 public static void DictonarySort(Dictionary<string, int> dic) { var dicSort = from objDic in dic orderby objDic.Value descending select objDic;

foreach (KeyValuePair<string, int> kvp in dicSort) Console.WriteLine(kvp.Key + "：" + kvp.Value + "<br />"); }

//字典升序排序方法 public static void DictonarySort(Dictionary<string, int> dic) { var dicSort = from objDic in dic orderby objDic.Value ascending select objDic;

foreach (KeyValuePair<string, int> kvp in dicSort) Console.WriteLine(kvp.Key + "：" + kvp.Value + "<br />"); }

// Stack  堆栈    后进先出 Stack<int> sta = new Stack<int>(); //int staCou = sta.Count; for (int i = 0; i < 10; i++) { sta.Push(i);//入栈 } sta.Pop();//出栈 foreach (var item in sta) { Console.WriteLine(item); }// Queue  队列    先进先出 Queue<int> que = new Queue<int>(); for (int i = 0; i < 10; i++) { que.Enqueue(i); }

Console.WriteLine(que.Dequeue() + "----------"); foreach (var item in que) { Console.WriteLine(item);
