我正在对系统进行一些修改,但遇到了一个异常,我希望有人能帮忙??我得到的错误如下:
异常详细信息:System.InvalidOperationException:传递到字典中的模型项的类型为“System.Collections.Generic.List
1[System.String]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable
1[MyApp.Data.aspnet_Users]”。
基本上我想要做的是显示非活动用户列表。这是我为此编写的控制器:
public ActionResult InactiveUsers()
{
using (ModelContainer ctn = new ModelContainer())
{
aspnet_Users users = new aspnet_Users();
DateTime duration = DateTime.Now.AddDays(-3);
var inactive = from usrs in ctn.aspnet_Users
where usrs.LastActivityDate <= duration
orderby usrs.LastActivityDate ascending
select usrs.UserName;
return View(inactive.ToList());
}
}
然后我从这里添加了一个局部视图。如果有人感兴趣,这是它的代码。只是通常的添加视图 --> 列表。
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<MyApp.Data.aspnet_Users>>" %>
<table>
<tr>
<th></th>
<th>
ApplicationId
</th>
<th>
UserId
</th>
<th>
UserName
</th>
<th>
LoweredUserName
</th>
<th>
MobileAlias
</th>
<th>
IsAnonymous
</th>
<th>
LastActivityDate
</th>
</tr>
<% foreach (var item in Model) { %>
<tr>
<td>
<%: Html.ActionLink("Edit", "Edit", new { id=item.UserId }) %> |
<%: Html.ActionLink("Details", "Details", new { id=item.UserId })%> |
<%: Html.ActionLink("Delete", "Delete", new { id=item.UserId })%>
</td>
<td>
<%: item.ApplicationId %>
</td>
<td>
<%: item.UserId %>
</td>
<td>
<%: item.UserName %>
</td>
<td>
<%: item.LoweredUserName %>
</td>
<td>
<%: item.MobileAlias %>
</td>
<td>
<%: item.IsAnonymous %>
</td>
<td>
<%: String.Format("{0:g}", item.LastActivityDate) %>
</td>
</tr>
<% } %>
</table>
<p>
<%: Html.ActionLink("Create New", "Create") %>
</p>
为了完整起见,这里是我呈现部分的索引页面:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Administrator.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Index
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Index</h2>
<% Html.RenderAction("InactiveUsers"); %>
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="Header" runat="server">
</asp:Content>
如果有人有任何建议,我将不胜感激:)
