You can't do this from the server-side. If you want to run some code server-side before going to the payment platform then you can submit a form to your page, that page can do the code then output a blank page with the same form you have above, only you can auto-submit it via javascript (google "auto submit form javascript" if you don't know how) so the user doesn't really see anything, it goes goes to the payment platform.

Strictly speaking, the question makes no sense, because your HTML does nothing, it does not submit anything to the server, because the "Submit" button is missing; it should be <input> element with the type="submit".

But if I could assume you have it all, your form would submit some data using the method "post". The HTTP request would contain all the form elements' data in key-value pairs, with keys equal to corresponding values of name attributes.

To do the same thing in ASP.NET code behind, you could use the class System.Net.HttpWebRequest:
