如何在動作結果中保存臨時值對象並在另一個動作結果中使用

Question

您好，我想在動作方法中保存一個臨時代碼，例如「代碼」，並在另一個動作方法中使用它來比較model.code是否輸入查看文本是「代碼」。但我不想把它保存到數據庫

這是我第一次的ActionResult方法，將持有的價值

[HttpPost] 
    [AllowAnonymous] 
    [ValidateAntiForgeryToken] 
    public async Task<ActionResult> PhoneReset(ForgotPasswordView model, string sms) 
    { 

     if (ModelState.IsValid) 
     { 
      var user = await UserManager.FindByEmailAsync(model.Email); 
      // 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 
      if (user != null || user.PhoneNumber==model.cellNumber) 
      { 
       //string code = await UserManager.GeneratePasswordResetTokenAsync(user.Id); 
       //var forgot = new ForgotPasswordBusiness(); 

       GenerateCodeBusiness gen = new GenerateCodeBusiness(); 

       var codes = gen.CreateRandomPassword(8); 
       SendSmsBusiness objap = new SendSmsBusiness(); 
       sms = "Your password reset code is " + codes; 
       objap.Send_SMS(model.cellNumber, sms); 
       await SignInAsync(user, isPersistent: false); 
       return RedirectToAction("ResetViaPhone", "Account"); 
      } 
      else if (user == null) 
      { 
       ModelState.AddModelError("", "The user does not exist"); 
       return View(); 
      } 
     } 
     // If we got this far, something failed, redisplay form 
     return View(model); 
    } 

這是第二次的ActionResult

 [HttpPost] 
    [AllowAnonymous] 
    [ValidateAntiForgeryToken] 
    public async Task<ActionResult> ResetPassword(ResetPasswordViewModel model) 
    { 


     if (!ModelState.IsValid) 
     { 
      return View(model); 
     } 
     var user = await UserManager.FindByNameAsync(model.Email); 
     if (user == null) 
     { 
      ModelState.AddModelError("", "No user found."); 
      return View(); 
     } 
     IdentityResult result = await UserManager.ResetPasswordAsync(user.Id, model.Code, model.Password); 
     if (result.Succeeded) 
     { 
      return RedirectToAction("ResetPasswordConfirmation", "Account"); 
     } 
     AddErrors(result); 
     return View(); 
    } 

這是輸入代碼的resetPassword視圖。

@model Template.Model.ResetPasswordViewModel 
@{ 
ViewBag.Title = "Reset password"; 
} 

<h2>@ViewBag.Title.</h2> 

@using (Html.BeginForm("ResetPassword", "Account", FormMethod.Post, new { @class = "form-horizontal", role = "form" })) 
{ 
@Html.AntiForgeryToken() 
<h4>Reset your password.</h4> 
<hr /> 
@Html.ValidationSummary("", new { @class = "text-danger" }) 
@Html.HiddenFor(model => model.Code) 




<div class="form-group"> 
    @Html.LabelFor(m => m.Email, new { @class = "col-md-2 control-label" }) 
    <div class="col-md-10"> 
     @Html.TextBoxFor(m => m.Email, new { @class = "form-control" }) 
    </div> 
</div> 
<div class="form-group"> 
    @Html.LabelFor(m => m.Password, new { @class = "col-md-2 control-label" }) 
    <div class="col-md-10"> 
     @Html.PasswordFor(m => m.Password, new { @class = "form-control" }) 
    </div> 
</div> 
<div class="form-group"> 
    @Html.LabelFor(m => m.ConfirmPassword, new { @class = "col-md-2 control-label" }) 
    <div class="col-md-10"> 
     @Html.PasswordFor(m => m.ConfirmPassword, new { @class = "form-control" }) 
    </div> 
</div> 
<div class="form-group"> 
    <div class="col-md-offset-2 col-md-10"> 
     <input type="submit" class="btn btn-default" value="Reset" /> 
    </div> 
</div> 

}

這是resetpassword模型

public class ResetPasswordViewModel 
{ 
    [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; } 

    public string Code { get; set; } 

任何援助將有很大的幫助

Answer 1

使用的TempData -

//Save values in tempData 
TempData["codes"] = codes; 

//Fetching the values in different action method 
//Note: Cast the tempdata value to its respective type, as they are stored as object 
var codes = TempData["codes"]; 

請注意，該值TempData只有在獲取其值後纔可用。一旦取得該值，它將被清除。

Tempdata中的值存儲爲對象，因此您需要將TemtData值轉換爲其各自的類型。
