古いパスワードと新しいパスワードは

Question

//Here Is my code below I am using Remote validation 

    public ActionResult Settings() 
     { 
      return View(); 
     } 

     //For checking New Password Doesnt match With Old Password 
     public JsonResult IsValidUsername(string newPassword) 
     { 
      AdminRepository service = new AdminRepository(); 
      return Json(service.IsValidUsername(newPassword), JsonRequestBehavior.AllowGet); 
     } 

     [HttpPost] 
     [ValidateAntiForgeryToken] 
     public ActionResult Settings(AdminViewModels model, FormCollection collection) 
     { 
      try 
      { 
       ModelState.Remove("EmailID"); 
       ModelState.Remove("IsValid"); 


       if (ModelState.IsValid) 
       { 
        AdminViewModels adminObj = (AdminViewModels)Session["Admin"]; 
        model.AdminID = adminObj.AdminID; 
        string newPassword = collection["NewPassword"]; 
        if (!string.IsNullOrEmpty(newPassword)) 
        { 
         bool exists = admin.PasswordUpdate(model, newPassword); 
         if (exists) 
          ViewBag.message = "Password Updated Successfully"; 
         else 
          ViewBag.messageinvalid = "Invalid Password"; 
        } 
        else 
        { 
         ViewBag.nullmessage = "Enter New Password"; 
        } 
       } 

       return View(); 
      } 
      catch (Exception ex) 
      { 
       return View("Error", new HandleErrorInfo(ex, "model", "collection")); 
      } 

     } 

はここ

public bool IsValidUsername(string newpassword) 
     { 
      using (dbHealthSplashEntities dbcontext = new dbHealthSplashEntities()) 
      { 
       return !dbcontext.Admins.Any(user => user.Password == newpassword); 
      } 
     } 

は、ここで私の見解モデル

public class AdminViewModels:IValidatableObject 
    { 
     public int AdminID { get; set; } 

     [Required(ErrorMessage = "EmailID is required")] 
     [StringLength(16, ErrorMessage = "Must be between 5 and 50 characters", MinimumLength = 5)] 
     [RegularExpression("^[a-zA-Z0-9_\\.-]+@([a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$", ErrorMessage = "E-mail is not valid")] 
     [EmailAnnotation] 
     public string EmailID { get; set; } 

     [Required(ErrorMessage = "Password is 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; } 


     [Required(ErrorMessage = "Enter New Password")] 
     //[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)] 
     [DataType(DataType.Password)] 
     [Display(Name = "newPassword")] 
     [Remote("IsValidUsername", "Admin", ErrorMessage = "It Seems You Have Entered Same Password As Old Password!!!")] 
     public string newPassword { get; set; } 

     [Required] 
     [System.ComponentModel.DataAnnotations.Compare("newPassword", ErrorMessage = "The password and confirmation password do not match.")] 
     public string ConfirmPassword { get; set; } 
     public Nullable<bool> Flag { get; set; } 

     public bool RememberMe { get; set; } 

     public bool IsValid { get; set; } 


     public IEnumerable<ValidationResult> Validate(ValidationContext context) 
     { 
      if (newPassword == Password) 
       yield return new ValidationResult("Passwords should not be the same"); 
     } 
    } 

です//私は私のリポジトリのコードです。// MVCで同じにすることはできません私の古いパスワードが新しいパスワードと一致することを確認できません 私は古いパスワードからそれを検証したいのですが、それがエラーを投げるべきであるよりもパスワードと一致する場合は、これを助けてください
