ASPNET MVC3技术要点

视图

@{

ViewBag.Title = "Index"; }

<h2>Index</h2> <p>

The day is: @(((DateTime)ViewData["Date"]).DayOfWeek) </p> <p>

The message is: @ViewData["Message"] </p> <p />

<h4>InlineHelper</h4> Days of the week: <p/>

@Html.CreateList((string[]) ViewBag.Days) <p />

Fruit I like: <p />

@Html.CreateList((string[]) ViewBag.Fruits) <p />

@Html.DropDownList("region", "Choose")

3.2.2.3 使用ViewModel ViewModel

public class ProductsListViewModel {

public IEnumerable<Product> Products { get; set; } public PagingInfo PagingInfo { get; set; } public string CurrentCategory { get; set; } }

动作函数

public ViewResult List(string category, int page = 1) {

ProductsListViewModel viewModel = new ProductsListViewModel {

Products = repository.Products

.Where(p => category == null || p.Category == category) .OrderBy(p => p.ProductID) .Skip((page - 1) * PageSize) .Take(PageSize),

PagingInfo = new PagingInfo {

CurrentPage = page, ItemsPerPage = PageSize, TotalItems = category == null ?
