跟踪C＃中的打印页数

Question

我正在为WPF中的窗口服务创建一个设置。该服务始终在我的系统中运行。我想得到打印页数。如果我要从我的计算机上打印任何文档，如doc，PDF，excel，该服务将自动计算打印页数和当前日期时间。然后它将为它创建日志。如何在WPF中使用C＃编码获取打印页数。

这可能会帮助你获得打印的数量

try
{
    string PrinterJobs = "SELECT * FROM Win32_PrintJob";
    ManagementObjectSearcher FindPrintJobs = new ManagementObjectSearcher(PrinterJobs);
    ManagementObjectCollection prntJobCollection = FindPrintJobs.Get();
    foreach (ManagementObject prntJob in prntJobCollection)
    {
        string jobName = prntJob.Properties["Name"].Value.ToString();
        string documentName = prntJob.Properties["Document"].Value.ToString();
        string nbcopie = prntJob.Properties["TotalPages"].Value.ToString();
    }
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message);
}

Just Applied IList<ManagementBaseObject>获取您PC上安装的所有网络打印机的列表。正如您的评论所示。

try
{
    IList<ManagementBaseObject> printers = new List<ManagementBaseObject>();
    string PrinterJobs = "SELECT * FROM Win32_PrintJob";
    ManagementObjectSearcher FindPrintJobs = new ManagementObjectSearcher(PrinterJobs);
    ManagementObjectCollection prntJobCollection = FindPrintJobs.Get();
    foreach (ManagementObject prntJob in prntJobCollection)
    {
        if ((bool)printer["Network"]) 
        {
            printers.Add(printer);
        }
        string jobName = prntJob.Properties["Name"].Value.ToString();
        string documentName = prntJob.Properties["Document"].Value.ToString();
        string nbcopie = prntJob.Properties["TotalPages"].Value.ToString();
    }
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message);
}
