如何在视图中显示数据 [英] How can i display data in a View

问题描述

如何在asp.net核心MVC中的视图中显示数据?在Index.cshtml中，我具有指向详细信息页面的以下链接.

How can i display data in views in asp.net core MVC?. In the Index.cshtml I have the following link to the detail page.

@Html.ActionLink("You_Controller_Name", "GetProductsDetail", new { id = item.ID }) |

我有这个控制器来通过ID获取产品

I have this controller to get product by ID

public IActionResult Detail()
{
   return View();
}

[HttpGet()]
public async Task<IActionResult> GetProductsDetail(string id)
{
  var product_list = (await ProductService.GetProducts()).ToList();
  var product = product_list.FirstOrDefault(a => a.ProductCode == id);
  return view(product);
}

需要在详细信息页面上显示产品信息的帮助.

Need help on displaying Product information in the detail page.

推荐答案

您应该在GetProductsDetail操作

return View("Detail", product);

阅读以下内容以更好地理解

已更新

您可以这样存储

@ViewBag.ProductName = product.ProductName

在视图中:

<h1>@ViewBag.ProductName</h1>

完整代码

[HttpGet]
public async Task<IActionResult> GetProductsDetail(string id)
{
   var product_list = (await ProductService.GetProducts()).ToList();
   var product = product_list.FirstOrDefault(a => a.ProductCode == id);
   @ViewBag.ProductName = product.ProductName

   return View("Detail", product); // Make sure that in View is expecting `ProductList`, Otherwise, You just return View("Detail");

}

从使用ASP.NET MVC 4的控制器
