Solution
Since you are sending model from form, try use HtmlHelper.
@using (Html.BeginForm("Save", "EmployeePc", FormMethod.Post)) { for (var i = 0; i < @Model.PC.Count; i++) { @Html.HiddenFor(m => m.PC[i].PCName) @Html.DisplayName(@Model.PC[i].PCName)
@Html.TextBoxFor(m => m.PC[i].PCId, new { htmlAttributes = new { @type = "number", @min = 0} })
}
}
In your View
<section class="content">
<div class="row">
<div class="col-xs-6 col-sm-8 col-md-6 col-lg-12">
<!-- /.card -->
<div class="card border-secondary mb-3">

Add [FromForm] to bind the model.
Your Controller
//[ValidateAntiForgeryToken]
[HttpPost]
public IActionResult Save([FromForm]EmployeePCVWModel employeePC)
{
if(ModelState.IsValid)
{
//
}
//
return View(employeePC);
}
