Using an enum as an array index in C#

Question

I want to do the same as in this question, that is:

enum DaysOfTheWeek {Sunday=0, Monday, Tuesday...};
string[] message_array = new string[number_of_items_at         


        

Answer 1

For future reference the above problem can be summarized as follows:

I come from Delphi where you can define an array as follows:

type
  {$SCOPEDENUMS ON}
  TDaysOfTheWeek = (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday);

  TDaysOfTheWeekStrings = array[TDaysOfTheWeek];

Then you can iterate through the array using Min and Max:

for Dow := Min(TDaysOfTheWeek) to Max(TDaysOfTheWeek) 
  DaysOfTheWeekStrings[Dow] := '';

Though this is quite a contrived example, when you are dealing with array positions later in the code I can just type DaysOfTheWeekStrings[TDaysOfTheWeek.Monday]. This has the advantage of the fact that I should the TDaysOfTheWeek increase in size then I do not have to remember the new size of the array etc..... However back to the C# world. I have found this example C# Enum Array Example.
