C# 首先使用代码使用MVC5实体框架更改密码

我正在尝试使用下面的控制器方法更新密码

  public ActionResult ChangePassword([Bind(Include = "NewPassword")] Register ChangePassword, FormCollection frm)
    {

        string Email = Session["email"].ToString();

        var existingEmail = db.Registers.FirstOrDefault(c => c.EmailId == Email);


        if (existingEmail != null)
        {
            //Need to update password

        }

        return View();


    }

下面是注册模型

   [Table("Register")]
public class Register
{
    [Key]
    public int Sno { get; set; }

    [Required(ErrorMessage = "Name is required.")]
    [Display(Name = "Full name")]
    public string Fullname { get; set; }
    [Display(Name = "Email Id")]
    [Required(ErrorMessage = "Email is required.")]
    public string EmailId { get; set; }
    [Required(ErrorMessage = "Password is required.")]
    public string Password { get; set; }

    [Required(ErrorMessage = "Mobile is required.")]
    public string Mobile { get; set; }
    [Required(ErrorMessage = "Address is required.")]
    public string Address { get; set; }
    public string State { get; set; }
    public string City { get; set; }
    [Required(ErrorMessage = "Entity is required.")]
    public string EntityType { get; set; }
    public string Website { get; set; }

    public string PinCode { get; set; }


      public string accountactivated { get; set; }

     public int RoleId { get; set; }

     [Display(Name = "New Password")]
      [NotMapped]
      public string NewPassword { get; set; }
     [Display(Name = "Confirm New Password")]
     [NotMapped] // Does not effect with your database
     [System.Web.Mvc.Compare("NewPassword", ErrorMessage = "Password not match")]
     public string ConfirmNewPassword { get; set; }


   }

下面是我更改密码的设计

    @using (Html.BeginForm())
  {
  @Html.AntiForgeryToken()

 <div class="form-horizontal">

    <hr />
    @Html.ValidationSummary(true)

    <div class="form-group">
        @Html.LabelFor(model => model.NewPassword, new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.TextBoxFor(model => model.NewPassword, new { @class = "form-control" })
            @Html.ValidationMessageFor(model => model.NewPassword)
        </div>
    </div>

    <div class="form-group">
        @Html.LabelFor(model => model.ConfirmNewPassword, new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.PasswordFor(model => model.ConfirmNewPassword, new { @class = "form-control" })
            @Html.ValidationMessageFor(model => model.ConfirmNewPassword)
        </div>
    </div>



    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" value="Change Password" class="btn btn-default" />
        </div>
    </div>
    </div>
    }

@使用（Html.BeginForm（））
{
@Html.AntiForgeryToken（）

@Html.ValidationSummary（true）
@LabelFor（model=>model.NewPassword，new{@class=“controllabel col-md-2”}）
@Html.TextBoxFor（model=>model.NewPassword，new{@class=“form control”}）
@Html.ValidationMessageFor（model=>model.NewPassword）
@LabelFor（model=>model.ConfirmNewPassword，new{@class=“control label col-md-2”}）
@Html.PasswordFor（model=>model.ConfirmNewPassword，new{@class=“form control”}）
@Html.ValidationMessageFor（model=>model.ConfirmNewPassword）
}

请帮助解决这个问题，并等待您的回复。我对使用asp.NETMVC代码开发我的项目非常陌生，这是我正在做的第一个项目。我提前表示感谢。
