Answer 1

There is an up-to-date sample code for PayPal C# api on that page PayPal C# API.

Answer 2

I believe that for beginners integrating with HTML API PayPal is probably the easiest and best way to get started.

This article is slightly outdated, but explains that option along with others in straightforward matter:

Answer 3

If all you need is simple Credit Card and PayPal Wallet payments - just use our new Restful Payment APIs - https://developer.paypal.com/webapps/developer/docs/api/

They are much more cleaner and simple APIs to begin with if that's all the payment functionality you need.
