将IAction方法中的Id捕获到asp.net核心中的另一个IAction方法

Question

[HttpPost]
public async Task<IActionResult> Register(ViewModel model,AppUser user )
{
  var app = db.AppUsers.Where(s => s.Name.Equals(s.Name)).ToList();
  ViewBag.App = app;
  if (!ModelState.IsValid)
  {

      return View();
  }

  //this is the registration table with RegistrationId as pk


  Registration registration = new Registration
  {
      FirstName = model.Registration.FirstName,
      LastName = model.Registration.LastName,
      EmailAddress = model.Registration.EmailAddress,
      PhoneNumber = model.Registration.PhoneNumber,
      Address = model.Registration.Address,
      Gender = model.Registration.Gender,

      RegistrationId = model.Registration.RegistrationId
  };
  db.Registration.Add(registration);

  await db.SaveChangesAsync();

  //here i'm passing the RegistrationId into an int that will be used as a foreign key in other tables
  int latestId = registration.RegistrationId;

  this.RegId = latestId;

  //this is the activity log table that have the RegistrationId as FK
  ActivityLog log = new ActivityLog
  {
      Purpose = model.Log.Purpose,
      NameOfCompany = model.Log.NameOfCompany,
      ToWhom = model.Log.ToWhom,

      Login = model.Log.Login = DateTime.Now,

      //here i implemented the latestId that was created above
      RegistrationId = latestId
  };
  db.Logs.Add(log);
  registration.RegistrationId = log.RegistrationId = latestId;
 await  db.SaveChangesAsync();

 // model.Registration = registration;
 //return View("Capture", model);

 //i did a redirect to action to pass the id to another view
  return RedirectToAction("Capture", "Registration", new {id = latestId});
}

public IActionResult Capture(string Id)
{

  return View();
}

[HttpPost]    
public async Task<IActionResult> Capture(ViewModel model,string name)
{
 //i want to use the latestId from the Register method on this Capture method
  int id = this.RegId;
  var files = HttpContext.Request.Form.Files;

  // Registration registration=  db.Registration.Where(s => s.RegistrationId == s.RegistrationId).FirstOrDefault();

  //int id = registration.RegistrationId;



  if (files != null)
  {

      {
          if (file.Length > 0)

              //Concatinating filename +fileExtension(Unique filename)
              var newFileName = string.Concat(myUniqueFileName, fileExtension);
              //Generating path to store photos
              var filePath = Path.Combine(hostingEnvironment.WebRootPath, "CameraPhotos") + $@"\{newFileName}";

              if (!String.IsNullOrEmpty(filePath))
              {
                  //Storing Image in folder
                  StoreInFolder(file, filePath);
              }

                  db.Bios.Add(new BioEntity

                      RegistrationId = id


                  });
               await db.SaveChangesAsync();



              //var imageBytes = System.IO.File.ReadAllBytes(filePath);
              //if (imageBytes != null)

private void StoreInFolder(IFormFile file, string fileName)

我有一个注册表和一个为我的应用程序保存图像的表。我需要将当前用户的注册ID从注册方法传递到图像捕获方法。该代码有效，但是一旦通过返回RedirectToAction（“ Capture”，“ Registration”，new {id = LatestId}）;有没有更好的方法可以做到这一点？

Note: I have the registration view and the image capturing view separately.
