Gotdotnet More detais about future C# features such as Generics, Anonymous Methods, Partial Types and simplified Iterators. (via SBC's weblog). Pretty exciting stuff. Here are quick examples from the presentation by Anders Hejlsberg: Generics, a form of C++ templates that makes reusing existing code easier List<int> intList = new List<int>(); intList.Add("one"); // Generates compile-time error Iterators, a construct that makes traversing collections of data significantly faster and easier public class List {     internal object[] elements;     internal int count;     public object foreach() {         for( int i=0; i<count; i++) yield elements[i]; } Anonymous methods, an easier way to perform simple tasks using delegates public class Bank {     ArrayList accounts;     ArrayList GetLargeAccounts( int minBalance) {        return accounts.Select( new Filter(a) { return ((Account)a).Balance >= minBalance;} );     } } Partial types, a means for programmers to split code across multiple files public partial class Customer {     private string name; } public partial class Customer {     public void DoSomething() { ... } }
