[Alex Smith]

Hi Friends,
I have trying to open a PDF file in richtextbox, a .txt file open
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)

{

fileopen.ShowDialog();

string fname = fileopen.FileName;

StreamReader sr = new StreamReader(fname);

string varread = sr.ReadToEnd();

richTextBox1.Text = varread;

sr.Close();

}

I have trying to open a PDF file in richtextbox, a .txt file open
successfully but a .pdf file open with unreadable form.

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:
