Combine return and switch

Question

How can I combine return and switch case statements?

I want something like

return switch(a)
       {
          case 1:\"lalala         


        

Answer 1

My mapping solution looks like Jordão's solution but it is more flexible and shorter.

return a
  .Map(1,"lalala")
  .Map(2,"blabla")
  .Map(3,"lololo")
  .Else(string.Empty);

Both arguments can also be a function:

return a
    .Map(x => x <= 0, "lalala")
    .Map(2, "blabla")
    .Map(x => x >= 3, x => "lololo" + x.ToString()); // lololo3 etc.
