I have tried every way to destroy TDictionary but whenever I have ReportMemoryLeaksOnShutdown active it always leaves something undetermined. I already tried to run the list and destroy item to item.

Code:

with foDict.GetEnumerator do
  while MoveNext do
    Current.Value.Free;

foDict.Free;

As I tried to destroy only foDict.Free;

There is both memory leakage. Anyone there have any suggestions?

Using your example, the code would have the following changes:

New class:

TMyCustomDictionary = TObjectDictionary<integer, TCliente>;

New use of foDict object:

foDict: TMyCustomDictionary;

New create foDict

foDict := TMyCustomDictionary.Create([doOwnsValues]);

Once this is done, the FreeList button is no longer useful

Test as follows:

destructor TMemCorrectedDictionary.Destroy;
begin
  inherited;
  Values.Free;
  Keys.Free;
end;
