Mastering C# and .NET Framework

Overview of this book

Mastering C# and .NET Framework will take you in to the depths of C# 6.0/7.0 and .NET 4.6, so you can understand how the platform works when it runs your code, and how you can use this knowledge to write efficient applications. Take full advantage of the new revolution in .NET development, including open source status and cross-platform capability, and get to grips with the architectural changes of CoreCLR. Start with how the CLR executes code, and discover the niche and advanced aspects of C# programming – from delegates and generics, through to asynchronous programming. Run through new forms of type declarations and assignments, source code callers, static using syntax, auto-property initializers, dictionary initializers, null conditional operators, and many others. Then unlock the true potential of the .NET platform. Learn how to write OWASP-compliant applications, how to properly implement design patterns in C#, and how to follow the general SOLID principles and its implementations in C# code. We finish by focusing on tips and tricks that you'll need to get the most from C# and .NET. This book also covers .NET Core 1.1 concepts as per the latest RTM release in the last chapter.

Chapter 5. Reflection and Dynamic Programming

The principles of Reflection in computer science are defined by Wikipedia as:

The ability of a computer program to examine, introspect, and modify its own structure and behavior.

The internal structure of the .NET assemblies we saw in the first chapter allows us to load and invoke types embedded inside our own or foreign assemblies at runtime with a technique called dynamic invocation.

Moreover, classes related to CodeDOM and Reflection.Emit namespaces permit code generation at runtime, either in C# or other languages, including Intermediate Language (IL).

However, beyond the .NET-to-NET dialogs, we can use Interoperability to manipulate applications built in other non-NET programming languages. Actually, many professional applications find it suitable—and very useful—to count on external functionalities that we might detect as present in the host operating system. This means that we can interoperate with Microsoft Office Suite (Word and Excel being...
