Passing values though the submit button?

I am trying to pass values thought the submit button of a form.

These are the values i need:

[HttpPost]
        public ActionResult Upload() //string token, string filename, string moddate, object file
        {
            Dictionary<string, string> parameters = new Dictionary<string, string>();
                parameters.Add("Token", token);
                parameters.Add("FileName", filename);
                parameters.Add("ModDate", DateTime.Today.ToString());
                parameters.Add("File", file);

            String compleat = "Complete";  
            return View(compleat);              
        }

This is where i try get the values:

<form action="/Home/Upload" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
@string token = @Model.Token;
@string fileName = file.tostring();
@File actualfile = file;
<br>
<input type="submit" name="submit" value="Submit" />

I would like to do something like this, my JavaScript is probably wrong as i am new to it.

After the submit is clicked how can i access the variables from the home controller?

In MVC you want to work with viewmodels. There is also html.beginform helper to use so your code won't look so messy.

UploadViewModel.cs

public class UploadViewModel
{
    public string Token { get; set; }
    public string FileName { get; set; }
    public string ModDate { get; set; }
    public object File { get; set; }
}

HomeController.cs

    public ActionResult Upload()
    {
        TempData["Status"] = "";
        return View(new UploadViewModel());
    }

    [HttpPost]
    public ActionResult Upload(UploadViewModel upload) //string token, string filename, string moddate, object file
    {
        //*** Do something with the upload viewmodel

        // It's probably a good idea to store the message into tempdata
        TempData["Status"] = "Complete";
        return View();
    }

Upload.cshtml

@model UploadViewModel

@Html.Label(TempData["Status"].ToString())
@using (Html.BeginForm())
{
    @Html.LabelFor(model => model.Token)
    @Html.EditorFor(model => model.Token)
    @Html.LabelFor(model => model.ModDate)
    @Html.EditorFor(model => model.ModDate)
    @Html.LabelFor(model => model.FileName)
    @Html.EditorFor(model => model.FileName)
    <input type="submit" name="submit" value="Submit" />
}

This is pretty basic stuff, you should read up some tutorials. Like these: http://www.asp.net/mvc/tutorials
