Enumerations

Sunday, July 16th, 2017

Enumerations are structures which resemble classes but differ from them in that in the enum body we can declare only constants. A variety of logically connected constants can be linked by means of language. These language constructs are the so-called enumerated types.… Read more

Constants

Saturday, July 1st, 2017

Just like constants in mathematics, C# defines special fields of classes called constants. Like their name hints, once declared and initialized, constants maintain their values, forbidding their further modification.

There are two types of constants:

  • constants for which the value is set during the compilation (compile time constants)
  • constants which have their value set during the execution (run-time constants)

Compile time constants are declared using the C# modifier const:

[<access_modifiers>] const <type> <name>;

A secret not many C# programmers know is that compile time constants are static fields, even if they do not contain the static keyword, and the compiler forbids its usage in the declaration.… Read more
