as Operator
You can use the as operator in C# to convert a class into another class within the same inheritance hierarchy. The as operator is equivalent to using casting with some minor differences as will…
Polymorphism
Polymorphism allows classes to transform into a different class within its inheritance hierarchy. It allows a programmer to use objects of different types but treat them in their “general” form while…
Partial Classes
Partial classes allows you to define a class in multiple seperate files. For example, you can place all the fields, properties, and constructors inside a file, and place all the methods…
