从下拉列表中的月份和年份 ASP.NET 设计 MVC

我正在努力填写观看页面的月份和年份 cshtml 项目 asp.net mvc

这是一个观看页面代码


@model IEnumerable<project.models.productstatistics>



@{



 }



@Html.DropDownList/"ExpirationMonth", ExpirationMonthDropdown/

@Html.DropDownList/"ExpirationYear", ExpirationYearDropdown/


这是一个模特


public class ProductStatistics

{



 public IEnumerable<selectlistitem> ExpirationMonthDropdown

 {

 get

 {

 return Enumerable.Range/1, 12/.Select/x =&gt;



 new SelectListItem//

 {

 Text = CultureInfo.CurrentCulture.DateTimeFormat.AbbreviatedMonthNames[x - 1] + " /" + x + "/",

 Value = x.ToString//,

 Selected = /x == Model.ExpirationMonth/

 }/;

 }

 }



 public IEnumerable<selectlistitem> ExpirationYearDropdown

 {

 get

 {

 return Enumerable.Range/DateTime.Today.Year, 20/.Select/x =&gt;



 new SelectListItem//

 {

 Text = x.ToString//,

 Value = x.ToString//,

 Selected = /x == Model.ExpirationYear/

 }/;

 }

 }



}


但在这里，我在类类中获得以下错误

姓名 'Model' 在当前的上下文中不存在

在View页面上也会收到此错误

姓名 'ExpirationMonthDropdown' 在当前的上下文中不存在
</selectlistitem></selectlistitem></project.models.productstatistics>

    使用以下代码更改模型。


    public class ProductStatistics
    
{
    

    
 [Display/Name = "Product ID"/]
    
 public string Product_ID { get; set; }
    

    
 [Display/Name = "Product Name"/]
    
 public string ProductName { get; set; }
    
}
    

    
public class ProductStatisticsList
    
{
    
 public List<productstatistics> Products
    
 {
    
 get;
    
 set;
    
 }
    

    
 public int SelectedMonth
    
 {
    
 get;
    
 set;
    
 }
    
 public int SelectedYear
    
 {
    
 get;
    
 set;
    
 }
    
}


    在行动中


    public ActionResult Index//
    
{
    
 ViewBag.Months = new SelectList/Enumerable.Range/1, 12/.Select/x =&gt;
    
 new SelectListItem//
    
 {
    
 Text = CultureInfo.CurrentCulture.DateTimeFormat.AbbreviatedMonthNames[x - 1] + " /" + x + "/",
    
 Value = x.ToString//
    
 }/, "Value", "Text"/;
    

    

    

    
 ViewBag.Years = new SelectList/Enumerable.Range/DateTime.Today.Year, 20/.Select/x =&gt;
    

    
 new SelectListItem//
    
 {
    
 Text = x.ToString//,
    
 Value = x.ToString//
    
 }/, "Value", "Text"/;
    

    
 ProductStatisticsList p = new ProductStatisticsList//;
    
 // p.Products = new List<productstatistics>//;
    
 //p.Products.Add/new ProductStatistics { Product_ID = "Product_ID", ProductName = "ProductName" }/;
    
 p.Products = /from productstatistics in db.ProductStatistics
    

    
 select new ProductStatistics
    
 {
    
 Product_ID = productstatistics.Product_ID,
    
 ProductName = productstatistics.ProductName,
    

    
 }/.ToList//;
    

    

    

    
 p.SelectedMonth = 3;
    
 return View/p/;
    
 }
    

    

    
 [HttpPost]
    
 public ActionResult Index/ProductStatisticsList model/
    
 {
    
 //do the stuff
    
 }


    依你的意见


    @model project_name.Models.ProductStatisticsList
    

    
@{
    

    
 }
    

    
 @using /Html.BeginForm/"index", "Home", FormMethod.Post, new { id = "formIndex" }//
    
{
    

    
 @Html.DropDownListFor/model =&gt; model.SelectedMonth, /IEnumerable<selectlistitem>/ViewBag.Months, "Month"/ 
    
 @Html.DropDownListFor/model =&gt; model.SelectedYear, /IEnumerable<selectlistitem>/ViewBag.Years, "Year"/ 
    

    
 <table class="table">
    
 @if /Model.Products != null &amp;&amp; Model.Products.Count &gt; 0/
    
 {
    

    
 <tr>
    
<th>
    
 @Html.DisplayNameFor/modelItem =&gt; Model.Products[0].Product_ID/ @*This approch is wrong , should read from resource file*@

<th>
    
 @Html.DisplayNameFor/modelItem =&gt; Model.Products[0].ProductName/ @*This approch is wrong , should read from resource file*@
    
 </th>
    
</tr>
    

    
 for /var i = 0; i &lt; Model.Products.Count; i++/
    
 {
    
 <tr>
    
<td>
    
 @Html.DisplayFor/modelItem =&gt; Model.Products[i].Product_ID/
    
 @Html.HiddenFor/modelItem =&gt; Model.Products[i].Product_ID/
    
 </td>

</tr>
    
 }
