.NET3.5

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:

C#

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);

And? Did you have some sort of a question? Are you properly disposing your objects so that the GC and collect them? Is the GC running at all? How exactly are you determining that the memory is not being released? What is it about your uncompilable sample code are we supposed to be looking at?

Yes i have tried with GC but still the memory is not released, with the help of task manager i am noting down the increase in the memory, it keeps on increasing when i add more jobs.
I have updated the code, now you can check.

Okay so your only evidence is that task manager shows that memory is increasing? Did you know that task manager lies? Do you know how the garbage collector works? You most likely do not have any kind of a problem at all.
