Delphi static method of a class returning property value
- by mitko.berbatov
I'm making a Delphi VCL application. There is a class TStudent where I have two static functions: one which returns last name from an array of TStudent and another one which returns the first name of the student. Their code is something like:
class function TStudent.FirstNameOf(aLastName: string): string;
var i : integer;
begin
for i := 0 to Length(studentsArray) - 1 do begin
if studentsArray[i].LastName = aLastName then
begin
result := studentsArray[i].FirstName;
Exit;
end;
end;
result := 'no match was found';
end;
class function TStudent.LastNameOf(aFirstName: string): string;
var i : integer;
begin
for i := 0 to Length(studentsArray) - 1 do begin
if studentsArray[i].FirstName = aFirstName then
begin
result := studentsArray[i].LastName;
Exit;
end;
end;
result := 'no match was found';
end;
My question is how can I avoid writing almost same code twice. Is there any way to pass the property as parameter of the functions.
