    successfully but a .pdf file open with unreadable form.
    I have trying with

    OpenFileDialog fileopen = new OpenFileDialog();

    PdfLib.PdfClass newpdf = new PdfLib.PdfClass();

    void Browse_Click(object sender, EventArgs e)



    string fname = fileopen.FileName;

    StreamReader sr = new StreamReader(fname);

    string varread = sr.ReadToEnd();

    richTextBox1.Text = varread;

    That's because PDF files are binary files whose content is not directly
    readable (not without understanding the file format and performing a fairly
    considerable amount of processing in order to extract it).

    RichTextBoxes can't display PDF file content, I'm afraid.

    If you're developing a web application, all you can do is send the PDF file
    to the browser and allow it to save or open it in whatever way it sees fit.

    If you're developing a Windows forms application, you might be able to find
    a third party control which is able to display PDF files, though I'm not
    aware of one off the top of my head. Otherwise all I can think of is to open
    the PDF file in the user's PDF viewer application (usually Acrobat Viewer).
    You can see an easy way to do this here:


    Hope that helps,
