I think for a C# developer with .NET background, the best way to enter functional programming is to learn F#.

Shameless plug: I'm the co-author (well, glorified editor really :) of <a href="http://manning.com/petricek" rel="nofollow noreferrer">Real World Functional Programming</a>. It's squarely aimed at people such as yourself. It teaches the principles of functional programming, mostly via F#, and also shows how you can apply the same principles in many cases in C#.

It assumes you know C# already, but introduces F# from scratch. It gives you enough knowledge of F# to get you started so you can experiment, but the aim is to teach a functional way of thinking rather than going into every nook and cranny of F# as a language. (In other words, if you want to start using F# as a production language, I'd get another book as well.)

It's not out yet, but you can get early access via the MEAP programme. Several chapters are available already, with more coming soon.

If you look at the Project Euler <a href="http://projecteuler.net/index.php?section=statistics" rel="nofollow noreferrer">stats</a>, Python and Haskell are very highly ranked.

blocks|key|458662|text|Real+World+Haskell的免费在线版本是一个很好的、便宜的入门方式。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|458663|一旦你完成了几章，你就可以决定FP是否适合你，以及你是想继续使用Haskell还是转向其他语言。你甚至可以继续购买dead+tree版本(就像我一样)。|458664|你从本书中学到的范例，特别是开头的章节，同样适用于其他函数式语言。(我喜欢认为我的Javascript和Groovy得益于我对Haskell的研究)。|458665|entityMap|0|LINK|mutability|MUTABLE|url|http://book.realworldhaskell.org/^0|0|I|0|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|C|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]]]

The free online version of <a href="http://book.realworldhaskell.org/" rel="nofollow noreferrer">Real World Haskell</a> is a good, cheap way to get started.

Once you've done a few chapters, you'll be in a position to decide whether FP is for you, and whether you want to continue with Haskell or move on to some other language. You may even go on to buy the dead tree version (as I did).

The paradigms you learn from this book, especially the opening chapters, apply equally well to other functional languages. (I like to think my Javascript and Groovy benefited from my studying Haskell).

blocks|key|4523610|text|花点时间看看Lisp或Scheme，因为它们是函数式编程之父和之母。PLT+Scheme是一个很好的使用方案的环境。给自己弄一个The+Little+Schemer的副本，因为它是一个很好的方案介绍，并将帮助您快速掌握它。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4523611|一旦你掌握了函数式，试着用函数式的方式解决一些Project+Euler问题。|4523612|entityMap|0|LINK|mutability|MUTABLE|url|http://www.plt-scheme.org/|1|http://www.ccs.neu.edu/home/matthias/BTLS/|2|http://projecteuler.net/^0|Y|A|0|1S|I|1|0|N|D|2|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]|$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@$A|Z|B|10|1|11]]|C|$]]|$1|F|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]|P|$5|I|J|K|C|$L|Q]]]]

Spend some time looking at Lisp or Scheme as they're the mother and father of functional programming. <a href="http://www.plt-scheme.org/" rel="nofollow noreferrer">PLT Scheme</a> is a great environment to play with Scheme. Get yourself a copy of <a href="http://www.ccs.neu.edu/home/matthias/BTLS/" rel="nofollow noreferrer">The Little Schemer</a> as it's a good introduction to Scheme and will help you get up to speed fairly quickly.

Once you've got your head around functional try doing some of the <a href="http://projecteuler.net/" rel="nofollow noreferrer">Project Euler</a> problems in a functional way.

I learned functional programming in college, using language <a href="http://www.haskell.org/" rel="nofollow noreferrer">Haskell</a>.

In its homepage you most likely find what you need to get started :)

BTW, it takes a lot of practice to see the solution; algorithms, as such, are not what everybody's used to code in Object-Oriented, logic or procedural languages.

blocks|key|3678291|text|我同意Mehrdad的观点。如果您熟悉C#，那么可以开始使用F#进行函数式编程。语法类似于C#中的lambda表达式。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3678292|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I agree with Mehrdad Afshari. If you are familiar with C# start functional programming with F#. The syntax is similar to lambda expressions in C#.

With all the hype around functional programming, which are the best resources to getting started in functional programming [for a C# programmer]? I am not looking for C# 3.0 language improvements.

How can I get started with functional programming?
