Question

我在下面的代码行中出现内存泄漏。

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

我在下面尝试了解决方案。添加UpdateLayout无法解决问题。

由于Windows服务崩溃，我面临两个例外：

内存超出异常（在XpsDocument.GetFixedDocumentSequence（））

System.Windows.Markup.XamlParseException

System.Windows.Markup.XamlParseException
