ASP.NET - Send Information to Website

I have an asp.net webpage that only contains a textbox and a button. The user submits their email address using this webpage.

What I am trying to do now is take the information submitted by the user and go to another website. Where my "website/program" gives the different website the entered email address, and clicks the submit button.

If I where to physically go to the different website, there would be a textbox to enter the email. But since I am accessing the website from my page "behind the scenes" I cant manually enter their email address...

Is it poss开发者_如何学编程ible to do this, if so how? Also, my code behind is in VB.

Thanks!

Well it can be done, but the simpllicity of it depends on what this other webpage is. Will this webpage always be the same or can it change?

If it a dynamic website that will frequently change, then you will need to basically parse the html and emulate how the email address gets posted to the webpage. Look for the tag in the html and see what page it posts to.

What you want to do is use HttpWebRequest. This class can send information to another web page. Here is a tutorial on how to do what you are asking: http://www.jigar.net/howdoi/viewhtmlcontent106.aspx

And here is the MSDN documentation on it: http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest(VS.71).aspx

Keep in mind that my solution will work if the web site is using POST or GET, but some sites use Javascript. To do this, it will require you to build a javascript interpreter.
