我有多年的紐扣。喜歡2018 2017 2016 2015我正在使用for循環將年份作為按鈕。索引視圖@model List<MyRecord.Models.RecordList>var year = DateTime.Now.Year;for (var i = year; i > 2012; i--){ var j = @i - 1; <div class="col-md-1 "> @Html.ActionLink(i.ToString(), "MyPage", new { i = i }) </div>}<h3>@ModelYear.Year</h3>@foreach (var groupMonth in Model.Records.GroupBy(recordLists => new { recordLists.date.Value.Year, recordLists.date.Value.Month })){ <h3 class="monthHeader"> @System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(groupMonth.Key.Month)</h3> foreach (var recordLists in groupMonth) { <div class="row"> @Html.Partial("_PartialView", recordList) </div> }}控制器public ActionResult Archives(int i = 0){ var recordLists = new List<RecordList>(); if(i == 0) recordLists = _db.recordlists .Where(p => p.date.Value.Year == DateTime.Now.Year) .OrderByDescending(p => p.date) .ToList(); else recordLists = _db.recordlists .Where(p => p.date.Value.Year == i) .OrderByDescending(p => p.date) .ToList(); return View(new ModelYear{Records = recordLists, Year = i});}模型：命名空間 MyRecord.Models{using System;using System.Collections.Generic;公共部分類 RecordList { public int id { get; set; } public string title { get; set; } public Nullable<System.DateTime> date { get; set; }}public class ModelYear{ public int Year { get; set; } public List<RecordList> Records { get; set; }}}當我點擊任何一年時，我會根據月份顯示該年的記錄。我能夠獲得月份名稱，而不是年份。我的問題是我需要將所選年份顯示為標簽或標題；如果我點擊 2016，我應該會看到如下內容：**2016**Janrecord 1record 2如何顯示點擊的年份？

為什么不將它包含在 Model 類中：
public class Model
{
public int Year {get;set;}
public List<RecordList> Records {get;set;}
}
然后你可以在控制器中設置它：
public ActionResult Archives(int i = 0)
{
var recordLists = new List<RecordList>();
if(i == 0)
recordLists = _db.recordlists.Where(p => p.date.Value.Year == DateTime.Now.Year)
.OrderByDescending(p => p.date).ToList();
else{
recordLists = _db.recordlists.Where(p => p.date.Value.Year == i).OrderByDescending(p => p.date).ToList();
}
return View(new Model{Records = recordLists, Year = i});
}
并將其顯示在視圖中：
<h1>@Model.Year</h1>
@foreach (var groupMonth in Model.Records.GroupBy(recordLists => new { recordLists.date.Value.Year, recordLists.date.Value.Month }))
{
<h3 class="monthHeader"> @System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(groupMonth.Key.Month)</h3>
foreach (var recordLists in groupMonth)
{
<div class="row">
@Html.Partial("_PartialView", recordList)
</div>
}
}
