Capture Browser content from c# window application

[a1jit]

Hi Guys,

How do i capture content from a browser based on a specific URL..

Lets say i navigate to google.com, how do i capture the whole content into a variable..

for some reasons im generating some xml file on server side, so i want
my users to actually access the data from the window application..

Appreciate if some guidelines/reference can be provided to get me started with this.

thanks

Do you mean something like this? Has nothing todo with a browser, but it should capture the contents. If you wished to grab the URL from a browser that should be possible also.

			string html;
			System.Net.WebClient wc;  
			System.IO.Stream myStream; 
			System.IO.StreamReader myReader;

			wc = new System.Net.WebClient();
			myStream = wc.OpenRead(@"http://www.google.com");
			html = myReader.ReadToEnd();

			myReader.Close();
			wc.Dispose();

By the way, this post shouldnt really be in the C# syntax section, as it isnt syntax specific. For future reference you should only post in this section if you have a syntax issue, not just because your useing C# .

Oh ok, sorry for the posting in wrong section,

yea, thats the code i was looking for, thanks..

but i got a small error, that is
"use of unassigned local variable myReader

Not sure what shall i assigned it to..Any idea?

thanks a lott

you needed to declare myReader as new .
heres a way that uses a few less lines of code & less classes...

[size=2]System.Net.WebClient wClient = [/size][size=2][color=#0000ff]new[/color][/size][size=2] System.Net.WebClient();
 
 
[/size][size=2][color=#0000ff]byte[/color][/size][size=2][] buffer = wClient.DownloadData([url="http://www.google.co.uk"]http://www.google.co.uk[/url]);
 
 
[/size][size=2][color=#0000ff]string[/color][/size][size=2] html = System.Text.Encoding.Default.GetString(buffer, 0 , buffer.Length);
 
 
Console.WriteLine( html );

[/size]

i see, thanks a lott for all the help, is there any way to convert your code to read
the content of the webpage rather than the source code itself..thanks..

Not sure what you mean by

read the content of the webpage

as that is exactly what dynamic_sysops code does.

 

[a1jit]

no i mean, the code above reads the source . meaning it includes the html tags and the data that is in the webpage, so what i plan to do was just to read the body content..meaning lets say this page, i just want to read what is see here, in this page, so i dont want to read the codes to build this page, but i want to read the values on this page (data)..hope i did not confuse you..

Thats what HTML is... A mixture of tags and content, there is no real concept of values when dealing with HTML.

If you want to get to the text content then you will need to parse the tags to get at the content. If the HTML has a lot of content then you are probably going to have to invest some time in learning Regular Expressions as a way to parse out the tags etc.
