New UP some Linq


This post is yet another technology placeholder.


I found the other day my PDC 05 notes and specifically Linq which I thought I better check in on again. I came across Wes Dyer’s blog , which is sensational but my head hurts. Instantly like the guy as he has a good interest in board games.


The PDC expression back then was New UP (as in new;ing up something)  


An overview of the main feature lambda expression is well detailed here


My notes (incomplete – I will need to add reference to MSDN later):


Lambda expression – provide a more concise, functional syntax for writing anonymous methods
Identifiable by => and the keyword Func


Lambda expression tree – expression lambda expressions as a graph


extension methods – add methods to types that already exist (e.g. IEnumerable)


Object initializers – typical embedded .net objects


var keyword – same as type initializer


anonymous types – create new type based on predefined type (you dont need to specify type as it is inferred by result)


A good article on Lambda expressions, and the progression from .net 2.0,  can be found here
