Anonymous type, Enumerator and Lambda expression

Question

Via:

var Foo = new[]{ new {Something = 321}}; 

Why can I do (compile):

  Console.WriteLine( Foo[0].Something ); 

but not:

  Foo.ForEach(x => Console.WriteLine(x.Something)); 

Answer 1

Because Array only has a static ForEach method:

 var Foo = new[] { new { Something = 321 } }; Array.ForEach(Foo, x => Console.WriteLine(x.Something)); 

compiles and works.

Answer 2

to try

  Foo.ToList().ForEach(x => Console.WriteLine(x.Something)); 

since the ForEach extension is only available for lists

EDIT : tested and working.
