Question

我有一个问题，我不明白如何解决它。特别是我在项目（C＃，VB 2015）工作，包括订单，收据等，当我在调试模式下运行时，一切都很好。但是当我设置我的项目并运行我的应用程序时，出现了这个错误：

System.FormatException: PrintTicket XML is not well-formed. Root element is missing. ---> System.Xml.XmlException: Root element is missing.
   at System.Xml.XmlTextReaderImpl.Throw(Exception e)
   at System.Xml.XmlTextReaderImpl.ParseDocumentContent()
   at System.Xml.XmlTextReaderImpl.Read()
   at System.Xml.XmlLoader.Load(XmlDocument doc, XmlReader reader, Boolean preserveWhitespace)
   at System.Xml.XmlDocument.Load(XmlReader reader)
   at System.Xml.XmlDocument.Load(Stream inStream)
   at MS.Internal.Printing.Configuration.InternalPrintTicket..ctor(Stream xmlStream)
   --- End of inner exception stack trace ---

   at System.Printing.PrintTicketManager.ConvertDevModeToPrintTicket(Byte[] devMode)
   at System.Printing.PrintQueue.get_UserPrintTicket()
   at Simple.Printing.PrintService.PrintOrder(IEnumerable`1 templates, Order order, Shift shift, IList`1 printingPosts, SimpleConfiguration configuration, Boolean showPrices, Invoice invoice, Boolean skipPosts, Int32 postPosition)
   at Simple.Domain.Services.OrderService.<>c__DisplayClass3c.<PrintOrder>b__39()

我无法打印我的订单。我的程序被粉碎的代码是：

var printer = dialog.PrintQueue;
var ticket = printer.UserPrintTicket ?? printer.DefaultPrintTicket;
var capabilities = printer.GetPrintCapabilities(ticket);
ticket.CopyCount = post.Copies > 0 ? post.Copies : ticket.CopyCount;

系统格式异常+ PrintTicket
