Post index

@model IEnumerable<FormValidation.Models.Entity.Personel>
   

@foreach (var item in Model)
{
    <p>@item.Name</p>
    <p>@item.Surname</p>
    <p>@item.Age</p>
    <p>@item.City</p>
    
}

CodePudding user response：

just as the error indicates,you passed the single personel model to render the view with return View(personel);

However,the View requires IEnumerable<Personel>

If you just want to show the details of the model you just created ,modify your view :

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