Getting image from FormCollection in Controller (MVC)

Hello everyone from this community! I am a newbie and facing an issue in my application. Please find me a way out. Thanks in anticipation.

I am getting following error while passing image from my form (view) to my controller using FormCollection:

CS0029 : Cannot implicitly convert type 'string' to 'byte[]'

Here's my db class:

(line#52 is creating conflict in my controller)

namespace KaamAoTemplate.Models
{
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
public partial class User
{
public int UserID { get; set; }
[Required(ErrorMessage ="This field is required!")]
public string FirstName { get; set; }
[Required(ErrorMessage = "This field is required!")]
public string LastName { get; set; }
[Required(ErrorMessage = "This field is required!")]
public string DateofBirth { get; set; }
[Required(ErrorMessage = "This field is required!")]
public string Province { get; set; }
[Required(ErrorMessage = "This field is required!")]
public string City { get; set; }
public string PostalCode { get; set; }
[Required(ErrorMessage = "This field is required!")]
public string CnicNum { get; set; }
[Required(ErrorMessage = "This field is required!")]
public string Contact { get; set; }
[Required(ErrorMessage = "This field is required!")]
public string Email { get; set; }
[Required(ErrorMessage = "This field is required!")]
[DataType(DataType.Password)]
public string Password { get; set; }
[Required(ErrorMessage = "This field is required!")]
[DataType(DataType.Password)]
public string ConfirmPassword { get; set; }
[Compare("Password")]
[Required(ErrorMessage = "This field is required!")]
public string Qualification { get; set; }
[Required(ErrorMessage = "This field is required!")]
public string SkillSet { get; set; }
public byte[] ProfilePicture { get; set; }
public decimal Wallet { get; set; }
public Nullable<byte> Rating { get; set; }
public int GigCount { get; set; }
}
}
//here is my controller: (issue in line # 16 and 31 )

[HttpPost]
public ActionResult Signup(FormCollection form)
{
string FirstName = form["FirstName"];
string LastName = form["LastName"];
string DateofBirth = form["DateofBirth"];
string Province = form["Province"];
string City = form["City"];
string PostalCode = form["PostalCode"];
string CNIC = form["CNIC"];
string Contact = form["Contact"];
string Email = form["Email"];
string Password = form["Password"];
string Qualification = form["Qualification"];
string[] SkillSet = form["JobCat"].Split(',');
byte[] ProfilePicture = form.Get("profilepic");
User user = new User();
user.FirstName = FirstName;
user.LastName = LastName;
user.DateofBirth = DateofBirth;
user.Province = Province;
user.City = City;
user.PostalCode = PostalCode;
user.CnicNum = CNIC;
user.Contact = Contact;
user.Email = Email;
user.Password = Password;
user.Qualification = Qualification;
user.SkillSet = SkillSet.ToString();
user.ProfilePicture = ProfilePicture;
KaamAoDBEntities db = new KaamAoDBEntities();
db.Users.Add(user);
db.SaveChanges();
return View(user);
}

and here's what i have in my view:

for="fileupload">Upload Profile Picture
"file" name="profilepic" value="" id="fileupload">

Hi Just change this line

byte[] ProfilePicture = form.Get("profilepic");

to

byte[] ProfilePicture = Encoding.ASCII.GetBytes(form.Get("profilepic"));

please check below link.
You need to convert posted file into byte[]. then it will work. Try like below

//Read the uploaded File as Byte Array from FileUpload control.
Stream fs = form.Get("profilepic");
BinaryReader br = new BinaryReader();
byte[] bytes = br.ReadBytes((Int32)fs.Length);
