Post to an external form from a controller in mvc5

Question

I have a form in a mvc5 view with a button. I need to process this form in the controller and add a few more field values which is picked up from the controller and then posted to an external url.

@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Deal</h4>
        <hr />
        @Html.ValidationSummary(true)

        <div class="form-group">
            @Html.LabelFor(model => model.First_Name, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.First_Name, new { @class = "form-control" })
                @Html.ValidationMessageFor(model => model.First_Name)
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.Last_Name, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.Last_Name, new { @class = "form-control" })
                @Html.ValidationMessageFor(model => model.Last_Name)
            </div>
        </div>
<div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Save" class="btn btn-default" name="save" /> 
                <input type="submit" value="Register Deal" class="btn btn-default" name="submit" />
            </div>

        </div>

Controller

public ActionResult Create([Bind(Include = "Id,Name,Company,Telephone,Fax,Email,Title,Status,OpportunityAmount,First_Name,Last_Name,City,State,Country,Zip")] Deal deal, String submit)
    {
        if (ModelState.IsValid)
        {
           // do some processing and submit to another external form
        }


    }

Any thoughts on how we can accomplish this ?

One use case would be if an username is provided the user then i would need to query from database the first last name, age etc and submit it to registration form of another site

You can post using Web Request Method. E.g.

public void post()
{
    string URL = "http://";
    System.Net.WebRequest webRequest = System.Net.WebRequest.Create(URL);
    webRequest.Method = "POST";
    webRequest.ContentType = "application/x-www-form-urlencoded";
    Stream reqStream = webRequest.GetRequestStream();
    string postData = Request.QueryString; //you form data in get format 
    byte[] postArray = Encoding.ASCII.GetBytes(postData);
    reqStream.Write(postArray, 0, postArray.Length);
    reqStream.Close();
    StreamReader sr = new StreamReader(webRequest.GetResponse().GetResponseStream());
    string Result = sr.ReadToEnd();
}

string postData = Request.QueryString; //you form data in get format . How do i do this? – Prady Dec 12 '14 at 09:44
You have Request.QueryString in your controller, just get it and append with your extra fields – fly_ua Dec 12 '14 at 09:47
Thanks..Could you provide me a small example for appending the extra fields. I do get an error on Request .querystring Cannot implicitly convert type 'System.Collections.Specialized.NameValueCollection' to 'string' – Prady Dec 12 '14 at 09:54
Will that work http://stackoverflow.com/questions/3865975/namevaluecollection-to-url-query – fly_ua Dec 12 '14 at 11:31
