Reputation Awareness

What people think of you will greatly affect your growth in you company and the respect you are treated with. People tend to think that their opinion of you is factual and uninfluenced but in most cases reputations spread within sub-groups, individuals tend to look at others to fill in gaps and validate their thoughts. It is important to understand that opinions have origins which are usually based on some form of perceived fact, whether it is true or not however does not change its influence.

I tend to believe that only 50% of your job is directly linked to your professional skillset the rest consist primarily on your reputation which could include things such as your perceived dedication, perceived skillset, reliability, networking and relationships.

Some areas that affect your reputation in your influence sphere:

• Behavior/ Mannerisms
• Commitment/Reliability
• Skillset (Profession & Social)
• Position and achievements

It is important to have a healthy reputation where the perceived reputation is as close to the truth as possible. People don't need you to be good at everything before you will earn their respect but they need something they look up to more than the aspect that they despise (E.g. If you have a difficult character you might need to be brilliant in your profession).

Do not let wrong impressions go past without correcting them (e.g. if you are working hard and the perception is that you are not it needs to be addressed as you will be judged by reputation not by facts). On the other hand if there are positive areas in your reputation that people respond to take care to live up to that responsibility and grow even more in it.

Learn how to address discrepancies and convey your intentions/actions in such a way that there is little room for confusion.

Remember that preventing misunderstandings is easier than correcting them and winning a person is more important than winning the argument. Lastly avoidance can also be a form of prevention (but only in extreme cases), bad reputation spreads like a poison where it can takes years to build a good reputation.

C# Objects, Classes, Structs and Inheritance

As a developer it is important to structure you code intelligently, C# is no different. As a flexible and powerful object oriented language is critical that you understand its object structures to enable you to design and implement best practice applications. Sadly many developers lack the basic overview or have some gaps in their knowledge which can limit their conceptualization and object oriented design structures. 

Please bear with me as it’s a bit of a lengthy post, the source code is available for download

if you want to dive into the code itself.

Structures and Classes

The two main custom object types used in C# is Struct’s and Classes, this with enumerations and delegates all have one root type/base class, the System.Object class. Basically these are the main reusable groupings of sub elements; this structures define their relationship and interaction in the context of the container object (In this case a Struct or a Class).

•  Introduction to Structs

This is an easy object structure to implement, very fast and good to represent lightweight objects that will be used often. (When to use Struct’s and some more reading)

Syntax: [attributes] [modifiers] struct identifier [:interfaces] body [;]

• Introduction to Classes

This is the most used custom object structure that can be used to represent basic to very complex object structures, dependencies, behaviors and inheritances.

Syntax: [attributes] [modifiers] class identifier [:base-list] { class-body } [;]

Example of a basic student class and implementation:

Some main differences between Classes and structures

•  Structs are value types while classes are reference types
• How they are allocated in memory (Heap and Stack)
• Constructors have different rules, Struct can’t create parameterless constructor (You cannot use a struct until all the fields are initialized) and can be instantiated without using the New operator.
• Structs does not have inheritance like Class objects. It inherits only from the System.Object class although it can implement interfaces.

Closer look into the standalone class structure

A class is a composite container of elements and behaviors. It is important to understand the syntax and layout to be able to create the best representative object structure of what you want to accomplish. Some might even look familiar coming from Struct’s. Be sure to follow the standard naming convention.

Some common concepts:

• Namespaces (Organize classes and give then scope) *Check out at global namespace alias
• Operators (Symbols that specify which operations to perform in an expression)
• Access Modifiers (Keywords that depicts the accessibility of a member or a type)

Access Modifier	Description
Public	The most permissive level, there are no restrictions on accessing them
Private	The least permissive level, access only allowed from within the body of a class or struct.
Protected	This allows access from within the class and any subsequent derived classes
Internal	Accessible within the assembly that it is declared in. *Check out Internals exposed to other assemblies (InternalVisibleTo) very useful to expose internal methods to unit testing assemblies as example.
Protected Internal	Accessible to assembly it was declared in or from another where the class declaration derives from the original class. In essence allowing access for where either Protected or Internal criteria is met.

 

Main areas a class can consist of and tips on each:

 

Constructors	These are class methods that are executed when an object of a given type is created *Check out overloading and Object Initializer
Destructors	Destructors are used to destruct instances of classes.
Fields & Properties	These are attributes describing a class, properties are members with method like capability * Nullable value types (Using ? and ??) *Check out Auto Properties
Methods	Methods describe logically grouped behavior of a class or struct *Check out Named and optional Arguments *Pass by reference (Value vs. reference types) *Look at Out Parameters
Indexers	This resemble array like properties except that their accessors take parameters
Events	Events enable class/object to notify classes/objects when something of interest occur
Delegates	Flexible method containers that live can live in variables or declared inline *Check out inline delegates, closures and Lambda expressions
Interfaces
Constant, Read-Only and Static Fields	Some important keywords to control access and scope * Check out the Singleton pattern (Single class instance across all sessions)
Classes & Structs

 A more complete class example:

Basic Inheritance:

• Partial Classes (A class structure allowing it to be constructed from multiple locations)
• Interfaces (Describe a group of related functionalities using only their signatures)

More advance object relationships and inheritance

• Polymorphism

Using inheritance classes can have multiple types and implementations. Polymorphism is the ability to structure inheritance so that class implementations can take multiple forms.

Key-Word	Description
new	Used for Member Shadowing. Using new in an inherited class will allow you to create another method with the same name as that already exists higher up in the hierarchy (Regardless if the upper method was declared as virtual or not). Please note this is in the context of methods. *Keep in mind that both methods exist, and can be executed depending on how the object is casted.
virtual	This marks a method as replaceable in a class that derives from the class that implemented the virtual method.
override	This marks a method to replace a higher up method that was marked as virtual. Note that the original item cannot be executed.
sealed override	This will stop the overriding of a specific method in lower inheritance. The provides the final unchangeable method downwards

Overloading methods

Use different parameter types and sequences as a signature to allow for different implementations of the same method.

•  Abstract & Sealed Classes

The abstract keyword enables you to create classes and class members that are incomplete; this base class defines the structure that the derived classes must align to. 

Note: Abstract classes cannot be instantiated.
