Question : Delphi What is the best way to sort an Array of String

Even shorter:

uses
  Generics.Defaults,
  Generics.Collections;

procedure TForm1.Button1Click(Sender: TObject);
var
  StrArray: array of string;
begin
  SetLength( StrArray, 3);
  StrArray[0]:= 'Str 3';
  StrArray[1]:= 'Str 2';
  StrArray[2]:= 'Str 1';

  TArray.Sort<string>(StrArray); // <----------------
end;
