c# - How To Set Default Printer in Silverlight?

Question

I want to select printer in Silverlight program, just like ATM or POS that will automatically print without selecting printer.

I browse internet and found: http://bytes.com/topic/c-sharp/answers/255914-set-default-printer-machine, it says that using System.Management package, using ManagementObject and ManagementBaseObject class, but I cannot add/import the class.

How to add using System.Management in Silverlight, or is any other way to selectt printer in silverlight code?

Regards, Imam

您不能在 Silverlight 中本机执行此操作。“System.Management包”（如您所说）与 Silverlight 运行时不兼容，它是为完整的 .NET CLR 设计的。

如果您使用 Elevated Trust 运行 OOB，那么您可以使用AutomationFactory来实现此目标：-

 var scriptNetwork = AutomationFactory.CreateObject("WScript.Network");
 scriptNetwork.SetDefaultPrinter("nameOfPrinterToSetAsDefault");
