Well, the real point behind me asking, is why are there no books on "datastructures and algorithms" in C#, but there are tons in Java.
Like I said, they are similar, but the Java books does so in a Java way, and I would like to keep it strictly to a C# .NET way. I'm studying on my own, so I don't want to spread my resources too thin.
So I guess, C# or rather .NET, is geared more towards business and not academia? Why? I understand that Computer Science is about the science and not the language, but can we not learn Computer Science using C#?
However, C# is a pretty new language, and a lot of schools already had their introductory CS courses well established by then. And they didn't have C# when they were designed, and consequently, the demand for introductory data structures books using C# is
low. And anyways, such books focus on the concept of data structures and not necessarily the language used to implement that.
[I assumed you are looking for beginner level books; if my assumption is wrong, I apologize]
The deeper you go into CS, the more you will realize that CS is more about the solution to a problem (algorithm and stuff), and not about the language you use is a matter of personal taste and expressibility for a given problem domain.
