Update Image - It return Image file null.

Question

Here is my code. ' If ' condition is false it go to the else part.  

[HttpPost]

public ActionResult DetailsEdit(EmployeeData___TBL e, HttpPostedFileBase ImageFile)

{

if (e.ImageFile != null)

{

string filename = Path.GetFileNameWithoutExtension(e.ImageFile.FileName);

string extension = Path.GetExtension(e.ImageFile.FileName);

HttpPostedFileBase postedfile = e.ImageFile;

int length = postedfile.ContentLength;

if (extension.ToLower() == ".jpg" || extension.ToLower() == ".jpeg" || extension.ToLower() == ".png")

{

if (length <= 1000000)

{

filename = filename + extension;

e.ProfileImage = "~/images/" + filename;

filename = Path.Combine(Server.MapPath("~/images/"), filename);

e.ImageFile.SaveAs(filename);

db.Entry(e).State = EntityState.Modified;

// int a = db.SaveChanges();

db.SP_UpdateUserInfo(e.UserId,e.Name, e.EmailID, e.PhoneNo, e.Address, e.ProfileImage);

//TempData["UpdateMessage"] = "<script>alert('Data Updated Successfully.')</script>";

ModelState.Clear();

return View();

}
