Problem saving an uploaded image

This is my first question. Thanks to everyone who contributes to this site, it's been a huge help as I try to teach myself programming.

I'm having a problem saving an uploaded image. I think I'm doing something wrong with the image.save function. My code is as follows:

Controller:

[AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(string fileName, HttpPostedFileBase pic)
    {
        string mimeType = pic.ContentType;
        byte[] imagedata = new byte[pic.ContentLength];
        pic.InputStream.Read(imagedata, 0, pic.ContentLength);
        Image outfitImage = (Image.FromStream(new MemoryStream(imagedata)));
        string filePath = @"c:\test.jpg";
        outfitImage.Save(filePath);
        return View();
    }

View:

<% using (Html.BeginForm("Index","Test" ,FormMethod.Post,new {enctype="multipart/form-data"})) {%>

    <fieldset>
        <legend>Fields</legend>
     <p>
            <label for="fileName">Name:</label>
            <%= Html.TextBox("fileName") %>
     </p>
     <p>
        Upload new image: <input type="file" name="pic" />
     </p>
     <p>
            <input type="submit" value="Create" />
     </p>
    </fieldset>
<% } %>

The stack trace is as follows:

    Server Error in '/' Application.
A generic error occurred in GDI+.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Thanks so much for the help!

Are you trying to convert the image to a JPEG?

If not, you should just call pic.Save(@"C:\text.jpg").

You might be getting the error because ASP.Net does not have write access to the root of the C: drive. (GDI+ can give funny errors)
How and where is this code being run? (Cassini? IIS?)

I would just figure out where you want to store it relative to the web server, translate that to the file server, and then save it.

string relativePath = "~/somefolder/somefile.ext";
string diskPath = ControllerContext.HttpContext.Server.MapPath(newFileWebPath);
pic.SaveAs(diskPath);
