Утечка памяти в XpsDocument.GetFixedDocumentSequence ()

0 голосов
/ 28 мая 2018

Я получаю утечку памяти в строке кода ниже.

 var fixedSequence = xpsDoc.GetFixedDocumentSequence();
 if (fixedSequence == null) return;

Я попробовал ниже приведенные решения. Добавление UpdateLayout не может решить проблему.

Я смотрю нижедва исключения из-за сбоя службы Windows:

  1. Недостаточно памяти (в XpsDocument.GetFixedDocumentSequence ())
  2. System.Windows.Markup.XamlParseException

Сведения об исключении для System.Windows.Markup.XamlParseException
