Hello Everyone,
I Am trying to Take Profile image from the user and store it in Database. But i am Still Getting this Errors please Tell me Solution,
Error
The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.

My Model is:

public class RegisterViewModel
   {
       [Required]
       [DataType(DataType.Text)]
       [Display(Name = "First Name")]
       public string FirstName { get; set; }
       [Required]
       [DataType(DataType.Text)]
       [Display(Name = "Last Name")]
       public string LastName { get; set; }
       [Column(TypeName ="UserImage")]
       public byte[] UserImage { get; set; }
       [Required]
       [EmailAddress]
       [Display(Name = "Email")]
       public string Email { get; set; }

       [Required]
       [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
       [DataType(DataType.Password)]
       [Display(Name = "Password")]
       public string Password { get; set; }

       [DataType(DataType.Password)]
       [Display(Name = "Confirm password")]
       [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
       public string ConfirmPassword { get; set; }
   }

My Controller look like this

public async Task<ActionResult> Register(RegisterViewModel model,HttpPostedFileBase ImageFile)
        {
            //Adding Image into the Database
            using (var ms = new MemoryStream())
            {
                ImageFile.InputStream.CopyTo(ms);
                model.UserImage = ms.ToArray();
            }
                if (ModelState.IsValid)
                {
                    var user = new ApplicationUser { UserName = model.Email, Email = model.Email,FirstName=model.FirstName,LastName=model.LastName/*,UserImage=model.UserImage*/ };
                    var result = await UserManager.CreateAsync(user, model.Password);
                    if (result.Succeeded)
                    {
                        await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);

                        // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                        // Send an email with this link
                        // string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                        // var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                        // await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

                        return RedirectToAction("Index", "Home");
                    }
                    AddErrors(result);
                }

            // If we got this far, something failed, redisplay form
            return View(model);
        }

View Look Like this

@using (Html.BeginForm("Register", "Account", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
    @Html.AntiForgeryToken()
    <h4>Create a new account.</h4>

    @Html.ValidationSummary("", new { @class = "text-danger" })
    <div class="form-group">
        @Html.LabelFor(m => m.FirstName,new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.FirstName, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.LastName, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
