A good c# learning resource

Question

Hello,

 

     I've studied C# off and on the past 2 or 3 years. I know a good deal about the language, but I know there is still a lot to learn. My only problem with staying devoted to learning is the vast majority of materials available. This is a good thing, but as I have come to notice.. I'll start with one book and realize it's left something out. I'll look at another book and it's got something different, but left out some things I remember viewing from the previous book. I'm just curious if there is a book (or book(s)) available which cover everything about the language. Or maybe even some online materials. These don't have to be free.. I just really enjoy the language and want to become proficient with it.

 

Thanks,
