如何將Listbox的值保存到數據庫中？

我在asp.net MVC-3中開發我的項目。如何將Listbox的值保存到數據庫中？

在這些模塊中，我創建了一個創建團隊的視圖。這裏有一個項目名稱的下拉列表。和一個列表框（ListBox-1），用於從下拉列表中顯示所選項目的成員。，還有另一個列表框（ListBox-2）來傳送/選擇所選或所有記錄（成員的名字）。這是完美的使用JavaScript。

我必須將所有數據保存在該表單的數據庫中。因爲我必須保存在數據庫的第二個列表框（ListBox-2）中顯示的團隊成員的列表。這些我的問題，如何獲取該列表框（ListBox-2）的數據並將其保存在數據庫字段？

下面是我創建的團隊視圖... enter image description here

在這種形式的第一個下拉列表中顯示的項目名稱並且有兩個列表框的下拉列表下面這是用來顯示項目

的成員名稱

列表框的視圖代碼是如下..

Dropdownlist for Project 
    <%: Html.DropDownListFor(model => model.availableproject, new SelectList(ViewBag.Projects as System.Collections.IEnumerable, "project_id", "project_name"),"Select Project", new { id = "ddlCars" }) %> 


code of listbox. 
<div class="ddlModels" style="float:left; "> 
           <%-- <%: Html.ListBox("projectmembers_id") %> --%> 
           <%: Html.ListBoxFor(Models => Models.availableuser, new SelectList(Enumerable.Empty<SelectListItem>(), "user_id", "user_login_name"), 
          new { id = "ddlModels2" }) %> 


          </div> 

          <div style="display:inline; float:left; margin-left:5px; margin-right:5px; margin-top:10px;"> 
           <input type="button" name="add" id="alladd" onclick="CopyListsall();" value=">>" style="width:27px; height:15px; font-size:8px; color:#56a1d6;"/><br /> 
           <input type="button" name="add" id="add" onclick="CopyLists();"value=">" style="width:27px; height:15px; font-size:8px; color:#56a1d6;"/><br /><br /> 
           <input type="button" name="remove" id="allremove" onclick="RemoveListsall();" value="<<" style="width:27px; height:15px; font-size:8px; color:#56a1d6;" /><br />     
           <input type="button" name="remove" id="remove" onclick="RemoveLists();" value="<" style="width:27px; height:15px; font-size:8px; color:#56a1d6;" /> 
          </div> 

          <div class="ddlModels" style="float:left;"> 
          <%: Html.ListBoxFor(Models => Models.availableuser, new SelectList(Enumerable.Empty<SelectListItem>(), "user_id", "user_login_name"), 
          new { id = "ddlModels1" }) %> 
          <%-- <%: Html.ListBox("projectmembers_id") %>--%> 
          </div>

代碼模型（cs文件）的

namespace ProjectManagementSystem.Models 
{ 
    public class TeamCreate 
    { 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public int team_id { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     [DisplayName("Team Name")] 
     public string team_name { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public int project_id { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public string project_name { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public int projectmembers_id { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public int projectmemberuser_id { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public int user_id { get; set; } 


     public int SerialNumber { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     [DisplayName("Team Leader")] 
     public string user_real_name { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public int technology_skill_id { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public string technology_skill_name { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public string team_description { get; set; } 

     [Required(ErrorMessage = "Empty Not Allow")] 
     public int leader_id { get; set; } 


     public bool t1 { get; set; } 

     public List<user_master> availableuser; 
     public List<project_master> availableproject; 
     public List<team_master> availableteam; 
     public List<team_to_user> availableteamuser; 

     public List<technology_skill_master> availabletechnology; 

     public List<int> SelectSkill { get; set; } 
     public List<int> lbtechnologyskillname2 { get; set; } 

     public List<int> ddlModels { get; set; } 
     public List<int> ddlModels1 { get; set; } 

    } 
}

第二cs文件獲取數據..

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 

namespace ProjectManagementSystem.Models 
{ 
    public class TeamCreateFetch 
    { 
     private int counter = 1; 


     //ProjectManagementSystemEntities3 pb = new ProjectManagementSystemEntities3(); 
     public static IList<TeamCreate> all() 
     {  

      IList<TeamCreate> result = 
       (IList<TeamCreate>)HttpContext.Current.Session["team1"]; 

      if (result == null) 
      { 
       ProjectManagementSystemEntities3 pb = new ProjectManagementSystemEntities3(); 

       HttpContext.Current.Session["team1"] = result = 

        (from l in pb.team_master 
        join u in pb.user_master 
        on l.user_id equals u.user_id 
        select new TeamCreate 
        { 
         //SerialNumber= counter++, 
         team_id= l.team_id, 
         user_id = u.user_id, 
         team_name= l.team_name, 
         user_real_name=u.user_real_name, 


      } 

      return result; 
     } 
    } 
}

我的數據庫是如下...

表的名字 - team_master

team_id 
team_name 
user_id(FK with user_id of "user_master") 
team_description

表-2 name- team_to_user

user_id(PK) 
user_real_name

表-3名稱 - team_to _user

team_id (FK with team id of "team_master") 
user_id (FK with user_id of "user_master")

現在我有保存在USER_ID字段的表「team_to _user」第二列表框的值。

那麼如何在MVC-3中做到這一點？

我建議廢除雙重列表框，並執行它作爲一個單一MultiSelectListBox。

示範

public class MyClass { 
    [Required] 
    [Display(Name = "Items Selected (Use ctl + click to select multiple)")] 
    public int[] SelectedItems { get; set; } 
    public IEnumerable<ItemDTO> Items { get; set; } 
} 

public class ItemDTO { 
    public int ID { get; set; } 
    public string Name { get; set; } 
}

觀

@Html.LabelFor(model => model.SelectedItems):              
@Html.ListBoxFor(model => model.SelectedItems, new MultiSelectList(Model.Items, "ID", "Name", Model.SelectedItems)) 
@Html.ValidationMessageFor(model => model.SelectedItems)

在你的控制，只是環通的SelectedItems陣列和保存每個
