无法在表格中显示数据

Question

当用户打开表单时，我希望我添加到产品实例的数据在表单中可见，但我的产品实例没有显示在我的表单上。我错过了什么？

我的代码：

 public IActionResult CreateProduct()
        {
            var product = new Products() {

                ProductName = "name",
                Quantity = 5
            };
            return View(product);
        }
[HttpPost]
       
public IActionResult CreateProduct(Products product)
        {
            return View();
        }

**VIEW**

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@model Products

<form asp-action="CreateProduct" asp-controller="ModelB" method="post">

    @Html.TextBoxFor(a => a.ProductName, "", new { placeholder = "Product Name" })
    <br />
   
    @Html.TextBoxFor(a => a.Quantity, "", new { placeholder = "Quantity", type = "number" })
    <br />
    <button type="submit">add</button>


</form>

尝试将您的操作重命名为索引

[Route("~/home/index")]
 public IActionResult Index()
        {
            var product = new Products() {

                ProductName = "name",
                Quantity = 5
            };
            return View(product);
        }
