將數據從視圖傳遞到控制器和控制器以查看

Question

我將視圖中的日期傳遞給控制器​​，然後從控制器中查看這兩個日期之間的記錄數。隨着更多的一個記錄將獲取，所以我使用IEnumerable，所以我可以顯示記錄列表。但是在使用IEnumerable時，它無法從視圖中傳遞選定日期並傳遞給控制器​​。任何人都可以解釋爲什麼？

這是我的代碼：

查看：Index.aspx的

控制器

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Mvc; 
using ApricaCRMEvent.Models.CRM.DatabaseEntities; 
using ApricaCRMEvent.Models.CRM.DataLayer; 

namespace ApricaCRMEvent.Controllers.CRM 
{ 
    public class SearchDateWiseController : Controller 
    { 
     // 
     // GET: /SearchDateWise/ 
     CRM_Doctor_Request dateObj = new CRM_Doctor_Request(); 

     public ActionResult Index() 
     { 
      return View(); 
     } 

     [HttpPost] 
     public ActionResult Index(CRM_Doctor_Request model) 
     { 

    return View(SearchMDLNoDL.getDateWiseDetails(model.Date_Created,model.Date_Modified).ToList()); 
     } 

    } 
} 

雖然使用了IEnumerable顯示編譯錯誤

Line 49:   <%: Html.ValidationSummary(true, "Profile Updation was unsuccessful. Please correct the errors and try again.") %> 
Line 50: 
Line 51:   **<%= Html.HiddenFor(model=>model.Date_Created) %> 
Line 52:   <%= Html.HiddenFor(model=>model.Date_Modified) %>** 
Line 53:   <table> 

編譯器錯誤消息：CS1061：'System.Collections.Generic.IEnumerable'不包含'Date_Created'的定義，也沒有接受類型'System.Collections.Generic.IEnumerable'的第一個參數的擴展方法'Date_Created'可以找到（您是否缺少使用指令或程序集引用？）

Answer 1

您在本例中的視圖模型是IEnumurable。它只包含在枚舉器上定義的方法。你有兩個選擇。

選項之一：定義一個視圖模型，如以下

public class MyViewModel { 
    public CRM_Doctor_Request ReportRequests { get; set;} 
    public DateTime Date_Created { get; set;} 
    public DateTime Date_Modified { get; set;} 
} 

現在你可以使用這個視圖模型將數據傳遞到視圖。

第二個選項：使用ViewBag將日期傳遞給視圖。在你的控制器

ViewBag.Date_Created = dateCreated; 
ViewBag.Date_Modified = dateModified; 

現在，這些值現在可以從查看

個人而言，我會去選擇一個訪問，由於其清潔

Answer 2

嘗試這樣的：

<% foreach (var date in Model) { %> 
     <%= Html.HiddenFor(date=>date.Date_Created) %> 
     <%= Html.HiddenFor(date=>date.Date_Modified) %> 
    <% } %> 

希望能幫助到你。
