C# 即使CreateNoWindow为true，PdfilePrinter.Print仍会启动Adobe Acrobat reader

不知何故，使用Adobe Acrobat X，PdfilePrinter无法阻止Adobe以静默方式打印PDF页面

这是我的密码：

PdfFilePrinter.AdobeReaderPath = PDFExecPath;
var printer = new PdfFilePrinter(this.documentPath, this.printer);
printer.Print();

以下是PdfSharp的来源：

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = PdfFilePrinter.adobeReaderPath;
string args = String.Format("/t \"{0}\" \"{1}\"", this.pdfFileName, this.printerName);
//Debug.WriteLine(args);
startInfo.Arguments = args;
startInfo.CreateNoWindow = true;
startInfo.ErrorDialog = false;
startInfo.UseShellExecute = false;
if (this.workingDirectory != null && this.workingDirectory.Length != 0)
  startInfo.WorkingDirectory = this.workingDirectory;

已解决：

PdfFilePrinter.AdobeReaderPath = PDFExecPath;
var printer = new PdfFilePrinter(this.documentPath, this.printer);
printer.Print(1000);

打印（int毫秒）过载会杀死adobe acrobat程序。

这对我来说确实是一个错误。
