private TextBox findEmpy(){for(int i=1;i

LinkedList ll = new LinkedList(); for (int i = 0; i < 10; i++) { ll.AddLast(i); Console.Write("{0} ", ll.Last.Value); } Console.WriteLine(); LinkedListNode llnLastPrivous = ll.Last; do { Console.Write("{0} ", llnLastPrivous.Va...

就是写文件啊,循环list string str = Guid.NewGuid().ToString(); string strPath = "C:\\Program Files\\" + str + ".xls"; FileStream fs = File.Create(strPath); StreamWriter sw = new StreamWriter(fs, Encoding.Unicode); string strLin...

static void Main(string[] args) { List lst = new List { "a", "b", "a", "b", "c", "a", "1", "b" }; foreach (string s in F(lst, "a", 2)) Console.Write(s + " "); Console.ReadLine(); } static List F(List lst, string a, int n) { //...

List a; List b=a.Cast().ToList();

List list = new List();List strlist = new List();XmlDocument doc = new XmlDocument();doc.Load("文件名.xml");foreach (XmlNode node in doc.SelectSingleNode("//object").ChildNodes){ // 遍历object下的所有子节点 list.Add(node); // ...
