Silent Printing PDF File in C# and closing Adobe Popup

Printing is very common task in Desktop App. In this article i will demonstrate how to print a PDF File Silently. There are two approaches. First We can print the file using PDF Sharp ( a open source library to support PDF Related Operations) and Arobate exe. Second Approach is to intiate a process that call Acrobate now doubt both need at least acrobat installed on machine, as PDF Sharp can not render PDF It self. I will demonstrate the first way.
Add Reference to PDF Sharp. First inform PdfFilePrinter about path of Adobe reader exe on target machine.

PdfFilePrinter.AdobeReaderPath = @"C:\Program Files\Adobe\Reader 8.0\Reader\AcroRd32.exe";

///Then in next step create a instance of the class PdfFilePrinter and provide path of file to print and your default active printer.

try
{
PdfFilePrinter Pdfprinter = new PdfFilePrinter(filetoprint, printer);
Pdfprinter.Print();
}
catch(Exception ex)
{
throw ex;
}
Now get the Adobe Process and kill it if it has finished its job.

foreach (Process proc in Process.GetProcesses())
{
if (proc.ProcessName.StartsWith("Acro"))
{
if (proc.HasExited == false)
{
proc.WaitForExit(10000);
proc.Kill();
break;
}
else
{
proc.Kill();
break;
}
}
}
