New line problem while downloading data from url - Dotexe - Aug 6, 2017

Hello, i've problems while downloading data from url. This is my code so far

Code 
byte[] raw = wc.DownloadData("url");

            string webData = System.Text.Encoding.UTF8.GetString(raw);

            TextBox9.Text = (webData);

but the problem is that the whole content is on one line, however the textbox is multiline, i've heard i had to do something with regex but not sure what.🤝 in advance.

It depends on where you download it from. If you download http://site.com/document.txt, it will display it just fine. However, if you download an HTML data, you might have to replace some tags (e.g. p, br) with "\r\n", Environment.NewLine.

Not sure if you understood what I mean

Example:

Code 
WebClient wc = new WebClient();

byte[] raw = wc.DownloadData("url");

string webData = Encoding.UTF8.GetString(raw );

TextBox9.Text = webData.Replace("<br />", Environment.NewLine);

Yes it is an html data, and i had to replace these tags u mentioned, but i had no idea how to achieve it, i will do that when i get home and will let you know if works. Thank you !
EDIT: not working with this as well ;(

Depending on how much markup there is and what you want to extract, it may be worthwhile using a parser such as htmlagilitypack.

Also, download directly as a string.

Can you give a sample from the input html.

Code 
TextBox9.Text = Regex.Replace(webData, "<.*?>", string.Empty);

This will remove all of the tags, but since you want to add new lines, this is not gonna work for you because you have to check which tag makes it go on a new line and then replace that tag with \r\n or Environment.NewLine. Because the new line may be coming by some text, some text , div tag, etc.

If you give url I can write the code, otherwise it's just guessing what exactly you're trying to achieve...

The webpage you are parsing, the entire html markup of the page, or just give link to the page instead.

hastebin has some issues with the ssl btw, and I need to load it in wepbroxy...

Code 
TextBox9.Text = webData.Replace("\n", Environment.NewLine);

There you go
