Getting error on upload 2 file in mvc

Question

Mode:-

public class Patner

{

[Key]

public int PatnerId { get; set; }

[Required(ErrorMessage = "Patner name is required")]

[Display(Name="Patner Name: ")]

public string PatnerName { get; set; }

[Display(Name = "Id Proof: ")]

public string IdProof { get; set; }

[Display(Name = "Address Proof: ")]

public string AddressProof { get; set; }

}


View:-
 
@using (Html.BeginForm("Patner", "Home", FormMethod.Post, new { enctype = "multipart/form-data"}))

{

@Html.AntiForgeryToken()

@Html.ValidationSummary(true, "", new { @class = "text-danger" })

<p>

@Html.LabelFor(model => model.PatnerName, htmlAttributes: new { @class = "control-label col-md-2" })

@Html.EditorFor(model => model.PatnerName, new { htmlAttributes = new { @class = "form-control" } })

@Html.ValidationMessageFor(model => model.PatnerName, "", new { @class = "text-danger" })

</p>

<p>

@Html.LabelFor(model => model.IdProof, htmlAttributes: new { @class = "control-label col-md-2" })

<input type="file" name="file[]" id="file" accept=".doc" />

</p>

<p>

@Html.LabelFor(model => model.AddressProof, htmlAttributes: new { @class = "control-label col-md-2" })

<input type="file" name="file[]" id="file" accept=".doc" />

</p>

<p class="stdformbutton">

<input type="submit" value="Save" id="btnsubmit" class="btn btn-default" />

<input type="button" value="Cancel" onclick="location.href='@Url.Action("Patner","Home")';" class="btn" />

</p>

}

 

Controller :-

 

[HttpPost]

public ActionResult Patner(Patner patner, HttpPostedFileBase file)

{

if (ModelState.IsValid)

{

string path = Path.Combine(Server.MapPath("~/Upload"), Path.GetFileName(file.FileName));

file.SaveAs(path);

using (SolarDbContext db = new SolarDbContext())

{

patner.IdProof = file.FileName;

patner.AddressProof= ?

db.Patners.Add(patner);

db.SaveChanges();

}

ModelState.Clear();

ViewBag.Message = "Data successfully saved.";

}

return View();

}

How to upload both file with data?

Thanks
