System.Net.HttpWebRequest.Create(url), something simular.

Ok, what I which to acheive is to send my page to an email everytime a person views it.

The emailing part is ok, but how can I save the response.outputstream of my aspx page into a string, once it has run?

Yea it's an odd question I know.

I have this code, which does this from another page but I want to get the stuff from the page that is running.

private String readHtmlPage(string url)
{
String result;
System.Net.WebResponse objResponse;
System.Net.WebRequest objRequest = System.Net.HttpWebRequest.Create(url);
objResponse = objRequest.GetResponse();
using (System.IO.StreamReader sr = new System.IO.StreamReader(objResponse.GetResponseStream()) )
{
result = sr.ReadToEnd();
// Close and clean up the StreamReader
sr.Close();
}
return result;
}

you can catch the request.
look the example

Thanks, but this appends to the output stream, what I need is the output stream as a string, or am I missing something here :)

This looks very promising, how can I get the string instead of writinf to a file?

mmarinov

you can use this code in overriden void Close()

sr = new StreamReader(@"C:\FilterOutput\response.htm");
s = sr.ReadToEnd();
sr.Close();

and after that to send s to static variable in your class

so every time you submit a page at the end of the request you will send the content of this file and when you enter again in the PageLoad you can get it

I'm not sure how you chaps know this stuff, but I'm really impressed :)

Here is my solution: Thanks
