C # Learning Notes

C # has a lot of features, but the ordinary work of the opportunity to use a little, today have time to try to use a bit, wrote a code, which used the indexer, delegate, extension method, generics, anonymous type, anonymous method, object set initializer, immediately feel very high-end wood has ~ ~ ~

public class User {public int UserID {get; set;}        public string UserName {get; set;}    public int Age {get; set;}        } public class Mylist<t> {private t[] data;        Public MyList () {data = new t[0]; } public int Count {get {return data. Length;            }} public void Add (T t) {t[] temp = data; data = new T[temp.            Length + 1]; Temp.            CopyTo (data, 0); Data[data.        Length-1] = t;            } public T This[int index] {get {return data[index];}        set {Data[index] = value;}        }} public static class Schema {public delegate bool Condtion<t> (T T);            public static mylist<t> search<t> (this mylist<t> MyList, condtion<t> condtion) {            mylist<t> result = new mylist<t> ();   for (int i = 0; i < Mylist.count; i++)         {if (condtion (Mylist[i])) {result.                ADD (Mylist[i]);        }} return result; }} class Program {static void Main (string[] args) {mylist<user> US = new MyList            <User> (); for (int i = 1; i <=; i++) {us.                    ADD (New User () {UserID = i, UserName = "name" + I,            age = i}); } var result = us.            Search<user> (Delegate (User u) {return u.age > 80;});        Console.ReadLine (); }    }
