當我想在 Asp.net.Mvc 中發布我的表單時，我遇到了這個問題我該如何解決

InvalidOperationException：傳入 ViewDataDictionary 的模型項的型別為“FormValidation.Models.Entity.Personel”，但此 ViewDataDictionary 實體需要型別為“System.Collections.Generic.IEnumerable”的模型項1[FormValidation.Models.Entity.Personel ]'。

控制器

[HttpGet]
        public IActionResult Index()
        {
           

           
            return View();
        }


        [HttpPost]
        public IActionResult Post(Personel personel)
        {

            return View(personel);
        }

uj5u.com熱心網友回復：

正如錯誤指示的那樣，您通過了單人模型來呈現視圖return View(personel);

但是，視圖需要IEnumerable<Personel>

如果您只想顯示剛剛創建的模型的詳細資訊，請修改您的視圖：

@model FormValidation.Models.Entity.Personel
.......
    <p>@Model.Name</p>
    <p>@Model.Surname</p>
    <p>@Model.Age</p>
    <p>@Model.City</p>
