Asp.Net Core 3-1 - 将 Guid 返回到 controller 的其他操作视图？

Question

I have two actions 1- action:

 public IActionResult ShowFirstSubCategory(Guid category)
    {      

        var firstsubcategory = _admin.ShowFirstCategory(category);
        return View(firstsubcategory);
    }

2-action:

 public IActionResult EditFirstSubCategory(Category firstsubcategory)
    {
       
        if (!ModelState.IsValid)
        {
            return View(firstsubcategory);
        }         

        _admin.UpdateMainCategory(firstsubcategory);
        return View("ShowFirstSubCategory", firstsubcategory.ParentId);

    }

I want firstsubcategory.ParentId send to action view ShowFirstSubCategory

And get the amount in the action...

You are trying to show another view that has a different model than that the parameter you passed into it. Instead, you should be using RedirectToAction like below:

return RedirectToAction("ShowFirstSubCategory", new { category = firstsubcategory.ParentId});
