===Using delegates only=== |

<lang csharp> |
|||
using System; |
|||
using System.Collections.Generic; |
|||
class Program |
|||
{ |
|||
static void Main( string[] args ) |
|||
{ |
|||
List<Func<int>> l = new List<Func<int>>(); |
|||
for ( int i = 0; i < 10; ++i ) |
|||
{ |
|||
var captured_val = i; |
|||
l.Add( delegate() { return captured_val * captured_val; } ); |
|||
} |
|||
l.ForEach( delegate( Func<int> f ) { Console.WriteLine( f() ); } ); |
|||
} |
|||
} |
