delphi - 释放TMemoryStream不会导致内存泄漏吗？

Question

我正在将 TWebModule 与 Apache 一起使用。我遇到内存泄漏问题。下面的代码中是否没有释放ImageStream内存泄漏？如果我释放它，我就会遇到访问冲突。

procedure TWebModule1.WebModule1WebActionItem8Action(Sender: TObject;
    Request: TWebRequest; Response: TWebResponse; var Handled: Boolean);
  var
    RecNo: Integer;
    ImageStream: TmemoryStream;
  begin
    RecNo := StrToInt(Request.QueryFields.Values['RecNo']);
    Master.MoveBy(RecNo - Master.RecNo); // go to right record
    ImageStream := TMemoryStream.Create;
    with TGraphicField.Create(Master) do
    try
      FieldName := 'Graphic';
      SaveToStream(ImageStream)
    finally
      Free
    end;
    ImageStream.Position := 0; // reset ImageStream
    Response.ContentType := 'image/jpg';
    Response.ContentStream := ImageStream;
    Response.SendResponse
  end;

来自here :

If you use the ContentStream property, do not free the stream yourself. The Web response object automatically frees it for you.

话虽如此，为什么还要涉及 ImageStream 呢？为什么不直接使用:

Response.ContentStream := TMemoryStream.Create

并将图像直接保存到该流中？
