Printing File by using C#

I am developing C# application. In this C# program, i want to add print button so users may print any document they want by using this button. I managed to print a txt file by reading it. But if i choose a pdf file instead, program prints some error codes in result.

private void printButton_Click(object sender, EventArgs e)
{
    try
    {
        streamToPrint = new StreamReader("C:\\test.txt");
        try
        {
            printFont = new Font("Arial", 10);
            PrintDocument pd = new PrintDocument();
            pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
            pd.Print();
        }
        finally
        {
            streamToPrint.Close();
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}


private void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
    float linesPerPage = 0;
    float yPos = 0;
    int count = 0;
    float leftMargin = ev.MarginBounds.Left;
    float topMargin = ev.MarginBounds.Top;
    string line = null;

    linesPerPage = ev.MarginBounds.Height / printFont.GetHeight(ev.Graphics);

    while (count < linesPerPage && ((line = streamToPrint.ReadLine()) != null))
    {
        yPos = topMargin + (count *
           printFont.GetHeight(ev.Graphics));
        ev.Graphics.DrawString(line, printFont, Brushes.Black,
           leftMargin, yPos, new StringFormat());
        count++;
    }

    if (line != null)
        ev.HasMorePages = true;
    else
        ev.HasMorePages = false;
}

Besides these, is there any way to open ctrl-p menu on the document(printing options)? Then user may choose any printer he/she desires.

I would appreciate your helps.

My regards...

There is a PrintDialog class which should present those options. But I'm not sure this will get you far as Romano has brought up the point that you can't read the PDF without a library like iTextSharp or PDFSharp.

You can not read a pdf file line by line. PDF is a binary format, not a text format. To clearify this try to open the PDF file in notepad (or your prefered text editor). You can use one of the many available libraries to acomplish this anyway or write your own PDF interpreter. I would recommend the available library iTextSharp (http://itextpdf.com/)
