System.Printing Printqueue.AddJob方法在打印文档后消耗内存并且不会释放。 [英] System.Printing Printqueue.AddJob methods consumes memory and doesnt releases once the document is printed.

问题描述

大家好，



我在我的应用程序中使用.net framework 3.5使用System.Printing库。当我使用PrintQueue.AddJob在任何打印机上打印作业时，内存会增加并且不会释放它。仅在应用程序关闭时才会释放内存。

如果我打印的作业超过10个，那么我的应用程序会使用我计算机的所有内存，最后一切都会变慢。

我观察到内存使用量达到2GB，这是不可接受的。

调查后我发现当调用PrintqQueue.AddJob方法时内存会增加。



这是我的打印代码示例：

 PrintServer printServer =  new  PrintServer（ @  \\ shindede）; 
 PrintQueue PrintQ =  new  PrintQueue（printServer，  HP_Printer，PrintSystemDesiredAccess.AdministratePrinter）; 
 PrintQ.AddJob（  xyz， @  C：\ ProgramData \ MyComapny \PrintSoftware \Config \Print_Manager \INPUT \d7a8a71b-4e73-43ec-8ee9-bbe24b3ba2cb.xps ， false ）;

Hi All,

I am Using System.Printing library in my application with .net framework 3.5. When i Print job on any printer using PrintQueue.AddJob memory gets increased and doesnt releases it. Memory is released only if the application is closed.
If i print more than 10 jobs then my application uses all the memory of my computer and finally everything gets slows down.
I obeserved the memory usage goes to 2GB, which is not acceptable.
After investigation i found that Memory gets increased when PrintqQueue.AddJob method is invoked.

Here is my sample Code for printing:

PrintServer printServer = new PrintServer(@"\\sshinde");
PrintQueue PrintQ = new PrintQueue(printServer, "HP_Printer", PrintSystemDesiredAccess.AdministratePrinter);
PrintQ.AddJob("xyz", @"C:\ProgramData\MyComapny\PrintSoftware\Config\Print_Manager\INPUT\d7a8a71b-4e73-43ec-8ee9-bbe24b3ba2cb.xps", false);
