PDF直接打印使用adobereader

我尝试了这段代码用于PDF打印，但是当Adobe Reader打开时，给出了一个错误

文件和目录无法找到

代码运行良好，打开Adobe，但不加载文件打印。相反，它显示一个错误对话框。有人能告诉我我哪里错了吗?

private void PrintFormPdfData(byte[] formPdfData)
    {`enter code here`
        string tempFile;
        tempFile = Path.GetTempFileName();

        using (FileStream fs = new FileStream(tempFile, FileMode.Create))
        {
            fs.Write(formPdfData, 0, formPdfData.Length);
            fs.Flush();
        }
        try
        {
            string gsArguments;
            string gsLocation;
            ProcessStartInfo gsProcessInfo;
            Process gsProcess;
            gsArguments = string.Format("-grey -noquery -printer '"HP LaserJet 5M'" '"{0}'"", tempFile);
            gsLocation = @"C:'Program Files'Ghostgum'gsview'gsprint.exe";
            gsProcessInfo = new ProcessStartInfo();
            gsProcessInfo.WindowStyle = ProcessWindowStyle.Hidden;
            gsProcessInfo.FileName = gsLocation;
            gsProcessInfo.Arguments = gsArguments;
            gsProcess = Process.Start(gsProcessInfo);
            gsProcess.WaitForExit();
        }
        finally
        {
            File.Delete(tempFile);
        }
    }
