【问题描述】：
我对使用数组列表非常陌生，并且想了解如何将数据从控制器中显示数据，该控制器的方法中有一个数组到 MVC Razor 页面。我正在创建一个运行良好的登录名，但希望将捕获的数据从 Active Directory 显示到 UserLoginData.CSHTML 页面。我读到最好的方法是通过模型。任何帮助将不胜感激！ （我只想要 Razor 数据页面上的表中的 ArrayList。）
控制器：
在此处输入代码
public ActionResult UserLoginData(string username, string LblUserName, string
UserName, ArrayList AuthorizationGroups)
{
UserLoginModel model = new UserLoginModel();
UserName = username;
ViewBag.UserName = UserName;
model.UserName = UserName;
model.LblUserName = model.UserName;
model.AuthorizationGroups = AuthorizationGroups;
foreach (var item in AuthorizationGroups)
{
// Console.WriteLine(item);
model.item = item;
}
return View(model);
}
模型（属性）：
//Labels for UserLoginData:
public string LblUserName { get; set; }
public string LblTitle { get; set; }
public string LblPlantLocation { get; set; }
public string LblUserLoggedInTimeStamp { get; set; }
public string LblUserLoggedOutTimeStamp { get; set; }
public string LblDisplayName { get; set; }
public string LblEmail { get; set; }
//For the ArrayList of MemberGroups.
public ArrayList AuthorizationGroups { get; set; }
public ArrayList YardDogUserGroupMembers { get; set; }
public ArrayList MemberOfUserGroups { get; set; }
public ArrayList YardDogAdminGroupMembers { get; set; }
public object item { get; set; }
剃刀 CSHTML：
在此处输入代码
@model PW_Login.Models.UserLoginModel
@{
Layout = null;
/*
WebGrid webGrid = new WebGrid(source: Model, canPage: true, canSort: true,
sortDirectionFieldName: "PlantLocation", rowsPerPage: 50);
webGrid.Pager(WebGridPagerModes.All);
*/
}
<!DOCTYPE html>
<html>
<head>
<link href="~/Content/UserLogin.css" rel="stylesheet" />
<meta name="viewport" content="width=device-width" />
</head>
<body>
@using (Html.BeginForm("UserLoginData", "LoginController", FormMethod.Post, new { id =
"LoginDataForm", Class = "LoginDataForm" }))
{
//Html.ListBoxFor(model=>model.AuthorizationGroups, Model.AuthorizationGroups)
// string UserName = Session["UserName"].ToString();
<label></label>
//Html.LabelFor(model => model.UserName, @Model.UserName)
<table class="table">
<tr>
<th>
@Html.DisplayNameFor(model => model.UserName)
</th>
<th>
@Html.DisplayNameFor(model => model.UserPlantLocation)
</th>
</tr>
<tr>
<td>
<!--- Html.DisplayFor(modelItem => item.AuthorizationGroups) -->
@foreach ( var item in Model.AuthorizationGroups)
{
@Html.DisplayNameFor(Modelitem=>item)
}
</td>
</tr>
</table>
}
</body>
</html>
Controller中从AD获取信息的方法：
private void ShowUserInformation(SearchResult rs, string UserName)
{
UserLoginModel model = new UserLoginModel();
Cursor.Current = Cursors.Default;
model.UserName = UserName;
Session["UserName"] = UserName;
Session["LblUserName"] = UserName;
DateTime now = DateTime.Now;
string UserLoggedInTimeStamp = now.ToString();
model.LblUserLoggedInTimeStamp = DateTime.Now.ToString("yyyy/MM/dd hh:mm:ss tt");
//Push the UserName into the Label via the model.
if (rs.GetDirectoryEntry().Properties["samaccountname"].Value != null)
model.LblUserName = "Username : " +
rs.GetDirectoryEntry().Properties["samaccountname"].Value.ToString();
if (rs.GetDirectoryEntry().Properties["title"].Value != null)
model.LblTitle = "Title : " +
rs.GetDirectoryEntry().Properties["title"].Value.ToString();
//description returns null... need to find out active directory folder/subfolder.
if (rs.GetDirectoryEntry().Properties["physicaldeliveryofficename"].Value != null)
//PhysicalDeliveryOfficeName returns 110.
model.LblPlantLocation = "PlantLocation : " +
rs.GetDirectoryEntry().Properties["physicaldeliveryofficename"].Value.ToString();
if (rs.GetDirectoryEntry().Properties["member"].Value != null)
model.LblMemberGroup = "Member : " +
rs.GetDirectoryEntry().Properties["member"].Value.ToString();
//DisplayName or DistinguishedName is what I do believe is in the security group
"YardDogUser" or "YardDogAdmin".
if (rs.GetDirectoryEntry().Properties["distinguishedName"].Value != null)
model.LblDistinguishedName = "distinguishedName : " +
rs.GetDirectoryEntry().Properties["distinguishedName"].Value.ToString();
//NULL...
if (rs.GetDirectoryEntry().Properties["YardDogAdmin"].Value != null)
model.LblYardDogAdmin = "YardDogAdmin : " +
rs.GetDirectoryEntry().Properties["YardDogAdmin"].Value.ToString();
if (rs.GetDirectoryEntry().Properties["displayname"].Value != null)
model.LblDisplayName = "Display Name : " +
rs.GetDirectoryEntry().Properties["displayname"].Value.ToString();
if (rs.GetDirectoryEntry().Properties["email"].Value != null)
model.lblEmail = "Email Address : " +
rs.GetDirectoryEntry().Properties["email"].Value.ToString();
/*

【问题讨论】：
-
看，这就是为什么我强烈支持删除这些遗留类，如
ArrayList。让这些人的代码不再编译，清理一下框架。我的意思是这个人似乎特别从rs.GetDirectoryEntry()获得报酬，想象一下他正确地重写他的代码会得到多少报酬。 -
其中一些目录条目是嵌入了其他信息的对象。那么在重写这个时会有什么建议呢？......我愿意接受改进的想法。 ArrayList 速度很快，我决定使用那个时间的引用来获取数据。
