使用Adobe Reader进行PDF直接打印

Question

I tried this code for PDF printing but when Adobe Reader open this gives an error that

file and directory could not found

The code runs fine and opens Adobe but does not load the file for printing. Instead it shows an error dialog. Can anybody tell me where I am wrong?

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);
        }
    }

Answer 1

fs.Close() is missing. So the file cannot be opened by gsprint.

Note: Flush before Close is useless.
