delphi - 你能检查是否调用了 Exit()

Question

开发人员可以检查是否调用了 Exit 吗？

try
  {do some stuff}
  If Condition then
    Exit;
finally
  {Can I check here if Exit was called without checking Condition again?}
end;

Answer 1

Can I check here if Exit was called without checking Condition again?

没有。如果检查 Condition again 很昂贵，或者有副作用，那么你可以使用局部变量来指示 Condition是True .

var
  LCondition: Boolean;
...
LCondition := False;
try
  // do stuff
  LCondition := Condition;
  if LCondition then
    Exit;
finally
  // now check LCondition
end;
