[Help]Sending Email with form data

[Nickalbokid96]

Hey everyone, I'm back. I haven't been programming for some time now although I still remember quite a few. I need to refresh my memory, schools been in the way for quite awhile because it's extremely difficult (private school) Anyways back to the point, I'm trying to get a app to send all the form data to an email in the background process. How can this be done?
For example:

Ah, thanks. It's really helpful, especially since it's a video!

This is a function I use to send form data inside the web;

        string post_form_data(string url, string postData)
        {
            WebClient client = new WebClient();

            //client.Headers.Add("Cookie", cookie);
            client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");

            byte[] byteArray = Encoding.ASCII.GetBytes(postData);
            byte[] responseArray = client.UploadData(url, "POST", byteArray);

            return Encoding.ASCII.GetString(responseArray);
        } 

I'm not sure if it will help or not.
