I want to learn about Design Patterns and everywhere I see diagrams like this:
Is it UML or something else? I just need a quick reference to learn what do each of different lines mean? which one is inheritance, etc..
1 Yes it is UML. You can read more (with examples) about class diagrams and other UML diagrams e.g. at http://www.uml-diagrams.org/class-diagrams-overview.html
2 Although it is possible to Google out and print and pin up on your notice board some "UML cheat sheet" or "UML quick reference card" (e.g. http://www.holub.com/goodies/uml).
3 it is much better to first read a good book so that you know what is/is_not possible what is the structural/behavioral modeling etc. Explaining UML is not a thing that can be done on 1 single sheet of paper or in one single Stack Overflow answer
Here is a key that I found here
***EDIT #xmojmr's request, here is an updated diagram that I found here (detailed definitions can be found in the linked page):
I recommend you to read UML superstructure specification. Read Classes section to get
information about types of relationship applicable to structural diagrams defined in UML, and much more. This document is base document if you want to learn UML. Dowload it from this site UML Superstructure
Yes, is U.M.L.
You do can learn about applying Design Patterns, without getting into U.M.L., but, the original book, as well as, a lot of documentation uses U.M.L.
I suggest to learn about U.M.L., without Design Patterns, and later, learn about Design Patterns, with & without U.M.L.
Just my 2 cents.

I want to use a graph in C++, so that I can use it for storing cities and distances between them, and then try some path finding algorithms on it. Is there any built-in library, etc. which I can include in my project?
Like #include<vector>, etc. If not, kindly tell me same for C#.
If you want to do path-finding you just need some special forms of trees. Most of them are well described when you look at path-finding algorithms. As an example, you can use a priority queue which is suitable for storing the successors at the top of your tree (fast access).
Concrete implementations I can suggest are A*:
You can build your own heuristic method, which means that you can put in your own logic for travelling.
One implementation of it is a-star-algorithm-implementation.
How about the Boost Graph Library?
Boost usually provides very good libraries for data structures and algorithms.

I have been reading about (AOP) Aspect Oriented Programming and I could not find any good article on internet with its implementation in C#. Everyone are talking about AOP Frameworks.
The code the described in below reference is not working at all.
http://www.codeproject.com/Articles/11387/Aspect-oriented-programming-in-NET-Part-II
Can someone share any good implementation code on aspect oriented programming?
Or Else suggest a good AOP Framework to be implemented easily?
As, we are in need to implement AOP in our Project for logging printing and sending mails on completion of specific operations.
Have a look at PostSharp. It is a framework for AOP in .NET that is widely used. In contrast to other frameworks, it uses an approach that weaves the generated code into the intermediate language which is good for performance reasons.
On the website there are also lots of resources about AOP in general and how it can be used. There also is a free edition and a trial version.
However, if you need to only decorate some small portions of your code, using the Decorator pattern or something similar might also be an option.
http://www.codeproject.com/Tips/624586/Introducing-the-KingAOP-Framework-Part-1 seems to fit your need (I've not yet tested it though)

I'm working on the implementation of Artificial Bee Colony algorithm in optimization of fuzzy c-means clustering. Can anyone provide a link for C# library or class that might help in the code of the ABC algorithm?
I think this should help. Its a ready to implement ABC algorithm library written in C++ that I had developed.
Google doesn't immediately seem to reveal a C# implementation of the ABC algorithm, though there is a Java implementation which should translate quite well to C#.
ABC souds similar to ant colony optimisation. I found this app, which you can probably get the source for if you contact the authors. It requires .NET, so it might as well be written in C#. It's not exactly what you asked for, but it's something ;)
There is a recent article in MSDN magazine that has an implementation in C#, on a specific problem. It should provide a good starting point!

I have been looking for a great code arrangement tool for c#. It would be nice to have something that can arrange code into regions etc and put items into alphabetical order.
I have tried NArrange and while it works well it is a little clunky in the integration department and did give us issues mixing up xml comments.
Any recommendations free > paid would be fantastic.
Thanks.
Not free(sorry), but take a look to Resharper.
Have a look at regionerate
I use fxCop along with the r# plugin and find it pretty ok
What is the benefit of ordering methods alphabetically? Shouldn't they rather be ordered logically according to the problem they solve. Generally I believe that if you have so many methods in a class/file that you think it makes sense to order them alphabetically your model is wrong, and it would be more beneficial to split your code in more classes/files.
With regards to regions, I have a hard time seeing what the benefit is. I recommend that you read Jeff Atwood's (CTO of stackoverflow) blog post on regions.

Are there any open source algorithms in c# that solve the problem of creating a difference between two text files?
It would be super cool if it had some way of highlighting what exact areas where changed in the text document also.
There's also a c# port of Google's (Neil Fraser) diff, match and patch.
There is Menees Diff which will provide you with a C# diff implementation. The source code is included. I've used it in the past with good success wrapping it in my own implemenation.
How about this one? : DIFFPLEX
Check out diff. Here it is in the gnu project (open source, of course), and many more links to implementations are found in the wikipedia article. A comparison of different such programs is found here.
