I want to create an `ActionResult` to add a new record.
I plan to use the [HttpPost] `ProductEdit(Product model)` method.
Question.
How to add a list item to a property of type IEnumerable <T>?
Or how to make this decision simpler?
Product.cs
public class Product
{
public int ID { get; set; }
public string Name { get; set; }
public string Description { get; set; }
}MockProduct.cs
public class MockProduct
{
List<Product> productList;
public MockProduct()
{
productList = new List<Product>
{
new Product {ID = 1, Name = "Name_1", Description = "Description_1"},
new Product {ID = 2, Name = "Name_2", Description = "Description_2"},
new Product {ID = 3, Name = "Name_3", Description = "Description_3"},
};
}
public IEnumerable<Product> ProductList
{
get
{
return productList;
}
set
{
productList.Add(value as Product);
}
}
}
HomeController.cs
public class HomeController : Controller
{
MockProduct mckProduct;
public HomeController()
{
mckProduct = new MockProduct();
}
public IActionResult Index()
{
var model = mckProduct.ProductList;
return View(model);
}
public IActionResult ProductEdit()
{
Product model = new Product();
return View(model);
}
[HttpPost]
public IActionResult ProductEdit(Product model)
{
// ?????
mckProduct.ProductList.Append(model);
var v = mckProduct.ProductList;
return View(model);
}Edit.cshtml
