CSharp-Compile-Run-code

.NET is Microsoft’s free and open source framework for developing native software applications on Linux, macOS, and Windows. The power of cross-platform development allows developers to design, code, and run programs on a wide array of platforms.

This course is an introduction to developing .NET applications using C#. You’ll start start with a comprehensive review of C# and computer programming fundamentals: data types, conditionals, loops, methods, and more. You’ll then review the basics of object-oriented programming before diving into methods, exception handling, delegation, and events. With this foundation, you’ll continue building interfaces, collections, database operations, and multithreading. You’ll wrap up with process improvements using dynamic binding, garbage collection, and unmanaged resources.

By the end of this course, you’ll have hands-on experience with C# and .NET, and be ready to build applications using object-oriented programming principles on almost any platform.

Mastering C# and .NET

## Introduction

Every application is composed of classes and other types, as well as their methods, properties, indexers, and so on. Reflection lets us obtain type information while the program is running. For instance, we could discover what methods a class has, what properties it operates, and what interfaces it implements. Reflection is type discovery at runtime.

The reflective functionality of .NET is located in the `System.Reflection` namespace.  To obtain information on a type, we use the `System.Type` class. This class has methods like:

- `GetMembers()`: This returns a `MemberInfo[]` object.

- `GetConstructors()`: This returns a `ConstructorInfo[]` object.

- `GetMethods()`: This returns information on `MethodInfo[]` methods.

These are only a handful of the members exposed by the `Type` class. The list is much longer, but the methods mentioned here provide a general idea about the `Type` class.

## Obtain type information

To obtain information on a type, we must first get an instance of the `Type` class that’s related to the type we’re interested in. We can do that in three ways:

1. Use the `typeof` operator

2. Call the `GetType()` on a type we’re interested in

3. Call the static `Type.GetType()` method and provide the name of the type
