prDocument.PrintController = new System.Drawing.Printing.StandardPrintController();
                        prDocument.PrinterSettings.PrinterName = selectedPrinter;

        {
            try
            {
                int pagesPrinted = 0, jobID;
                string f_SearchQuery = "SELECT * FROM Win32_PrintJob";
                ManagementObjectSearcher f_SearchPrintJobs = new
                ManagementObjectSearcher(f_SearchQuery);
                ManagementObjectCollection f_PrntJobCollection = f_SearchPrintJobs.Get();

                foreach (ManagementObject f_PrntJob in f_PrntJobCollection)
                {
                    jobID = Convert.ToInt32(f_PrntJob.Properties["JobId"].Value.ToString());
                    pagesPrinted = Convert.ToInt32(f_PrntJob.Properties["PagesPrinted"].Value.ToString());
                }
                return pagesPrinted;
            }
            catch (Exception ex)
            {
                return 0;
            }
        }

但是pagesPrinted始终为零.

问题是什么.任何帮助将不胜感激.

推荐答案

在这里，伙计.
对打印页面进行计数 [使用WMI询问打印机查询 [在Windows下使用C#计数打印的页面 [ ^ ]

Here you go man.

Count Printed pages[^]

Interrogating your Printer Queries with WMI[^]

Counting Printed Pages in Windows under C#[^]

添加此内容:

Hi Add this:

prntJob.Properties["TotalPages"].Value.ToString();

它将为您提供帮助.
