Enumeration is basic C# type mostly used for increase readability of code and make variable type safety. Assume that we would like to use weekdays in some variable. We can create create int variable for it and assume that following numers (1-7) are associated with following weekdays. This would be enough but every user which will read our code should know about our assumptions to have no problems with analyze. Additionally...

C# provide two field modifiers for protection of field modification. Except of const keyword well-known from C++ we have additional readonly keyword in C#. So we have three levels of field modification protection in C#: private bool fieldName - such field cannot be modify outside class but can be modify inside private readonly bool fieldName - such field can be modified in constructor of class only (useful for variables which...

Instead of classic class field definition, C# adds one more class element - property. Sometimes there is hard to understand difference between field and property in C# for beginners.  Main difference is:  Field is just simple variable within class, while property is field wrapped in two functions: getter and setter. So in general, if you define property, compiler silently creates invisible field for that property make...

Because C# is object oriented programming language its class implementation allows using encapsulation mechanism.  Encapsulation is mechanism which allow hide some functionality within class or object to avoid its access from outside of that class or object.   Encapsulation is very useful in order to make protection for some operation and make them invoke in only one known place of code. Thanks to that we have...
