C#-几个STL相关

C#结构体排序

1................................................. 声明 struct data { public string A; public string B; } 创建测试数据 data[] st = new data[4] { new data() { A = "CC", B = "003" }, new data() { A = "BB", B = "002" }, new data() { A = "DD", B = "005" }, new data() { A = "AA", B = "007" } }; 按照 data.B 顺序排列 data[] basc = st.OrderBy(P => P.B).ToArray<data>(); 按照 data.B 倒序排列 data[] bdesc= st.OrderByDescending(P => P.B).ToArray<data>();2..........................................................struct data:IComparable<data>{ string A;string B;public int CompareTo(data d){return this.B.CompareTo(d.B);}}
队列

DirectoryInfo tou = null, xin = null;//文件类型 xin = (DirectoryInfo)s;//把参数s强制转换 Queue<DirectoryInfo> q = new Queue<DirectoryInfo>(); q.Enqueue(xin);//进队列 while (q.Count() != 0)//判断是否为空 tou = q.First();//取出 q.Dequeue();//删除 容器

static Dictionary<string, int> mark = new Dictionary<string, int>(); mark[myProcess.ProcessName] = 1; 赋值 mark.Remove();删除 mark.ContainsKey()查是否存在
