Capture page source code

To analyze a website page, you need to obtain the page source code to analyze the DIV tag and JS

Here we will first capture the page source code method

Using system. net;

Using system. IO;

 

 

Private string getpagecodes (string URL)

{

String strhtml = "";

Webrequest web = webrequest. Create (URL );

// Webresponse HWR = web. getresponse ();

Httpwebresponse HWR = (httpwebresponse) web. getresponse ();

// Use stream reading and determine the encoding method

Stream S = HWR. getresponsestream ();

Streamreader objreader = new streamreader (S, encoding. Default );

String strline = "";

While (strline! = NULL)

{

Strline = objreader. Readline ();

If (strline! = NULL)

{

Strhtml + = strline;

}

}

Return strhtml;

}

 

 

 

Assign the result to the user control.

Txtcontext. Text = getpagecodes ("http://www.pcpop.com /");

 

Capture is as follows:
