由于您是从表单发送模型，请尝试使用 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} })
}
}
在你看来

添加 [FromForm] 绑定模型。
您的控制器
//[ValidateAntiForgeryToken]
[HttpPost]
public IActionResult Save([FromForm]EmployeePCVWModel employeePC)
{
if(ModelState.IsValid)
{
//
}
//
return View(employeePC);
}
