Where is the URI of "another ASP.NET application" page which is supposed to accept the post data?

Please see my comment to the answer.

This is the first problem which catch an eye: where is the URI with the scheme "http" or "https"? You are using string url = "test@url.com"; which cannot be a Web page URI. You can upload the file with HttpWebRequest only if your have really existing Web page working through HTTP or HTTPS protocol on a currently running HTTP server; and this page should have the server-side code capable of receiving POST data and doing something with this data.

In the code you show, that "another ASP.NET application" simply does not exist.

Your question raises another question: do you really understand what HTTP does and how the Web works? It seems to me you need to learn about it; I don't even know what, maybe even learn from scratch.

Good luck with that,
