Тестовый reg-файл, который я использую для проверки:

        catch (Exception ex)
        {
            throw new Exception(String.Format("Exception thrown on processing string {0}", match.Value), ex);

    return dictKeys;
}

Я исправил регулярное выражение для обработки экранированных кавычек (\ ") следующим образом: 

string searchPattern = "^[\\t ]*(\"[^\"\\\\]*(?:\\\\.+[^\"\\\\]*)*\"|@)=(\"[^\"\\\\]*(?:\\\\.[^\"\\\\]*)*\"+)";

, но теперь это не так не разбирать не строковые ключи, т.е. BinaryData1. Я пытаюсь понять, какое регулярное выражение может обрабатывать все типы данных, но также включать в строки экранированные кавычки.

Вы можете обновить шаблон так, чтобы повторение совпадений не совпадало с \ или " ИЛИ с совпадением \, за которым следует любой символ. 

^[\t ]*(".+"|@)=("(?:[^"\\]|\\.)*"|[^"]+)
                   ^^^^^^^^^^^^^^

string searchPattern = @"^[\t ]*("".+""|@)=(""(?:[^""\\]|\\.)*""|[^""]+)";
