FormApp

Formlar ile güzel bir mini proje geliştirdim.
Views Sayfalarımızı bootstrap ile daha estetik hale getiriyoruz. Bir tane model ve modelimize uygun bir Repository hazırlıyoruz.
Product.cs ve ProductRepository.cs oluşturuyoruz.
Product.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace FormsApp.Models
{
    public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
        public decimal Price { get; set; }
        public bool isApproved { get; set; }
    }
}

ProductRepository.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace FormsApp.Models
{
    public static class ProductRepository
    {
        private static List<Product> _products;

        static ProductRepository()
        {
            _products = new List<Product>()
            {
                new Product(){ Id=1, Name="Product 1", Description="Description 1", Price=10, isApproved=true},
                new Product(){ Id=2, Name="Product 2", Description="Description 2", Price=20, isApproved=false},
                new Product(){ Id=3, Name="Product 3", Description="Description 3", Price=30, isApproved=true},
                new Product(){ Id=4, Name="Product 4", Description="Description 4", Price=120, isApproved=true},
                new Product(){ Id=5, Name="Product 5", Description="Description 5", Price=140, isApproved=false},
                new Product(){ Id=6, Name="Product 6", Description="Description 6", Price=160, isApproved=true},
                new Product(){ Id=7, Name="Product 7", Description="Description 7", Price=132, isApproved=true},
                new Product(){ Id=8, Name="Product 8", Description="Description 8", Price=154, isApproved=false},
                new Product(){ Id=9, Name="Product 9", Description="Description 9", Price=345, isApproved=true},
                new Product(){ Id=10, Name="Product 10", Description="Description 10", Price=100, isApproved=false}
            };
        }

        public static List<Product> Products
        {
            get { return _products; }
        }

        public static void AddProduct(int productLast, string Name, string Description, decimal Price, bool isApproved)
        {
            var item = new Product() { Id = productLast, Name = Name, Description = Description, Price = Price, isApproved = isApproved };
            _products.Add(item);
        }

    }
}

Controllers oluşturuyoruz. HomeController.cs.

using FormsApp.Models;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;

namespace FormsApp.Controllers
{
    public class HomeController : Controller
    {
        private readonly ILogger<HomeController> _logger;

        public HomeController(ILogger<HomeController> logger)
        {
            _logger = logger;
        }

        public IActionResult Index()
        {
            return View(ProductRepository.Products);
        }

        [HttpGet]
        public IActionResult Create()
        {
            return View();
        }

        [HttpPost]
        public IActionResult Create(string Name, string Description, decimal Price, bool isApproved)
        {
            /*Product product*/
            var productAll = ProductRepository.Products.Last();
            int productLast = productAll.Id+1;
            ProductRepository.AddProduct(productLast,Name,Description,Price,isApproved);
            return RedirectToAction("Index");
        }

        [HttpGet]
        public IActionResult Search(string q)
        {
            //gelen q değeri ile arama işlemleri yapılır.
            if (string.IsNullOrWhiteSpace(q))
            {
                return View();
            }
            else
            {
                return View("Index",ProductRepository.Products.Where(i=>i.Name.Contains(q)));
            }
        }

        [ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)]
        public IActionResult Error()
        {
            return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
        }
    }
}
