我收到此错误"System.NotSupportedException:无法在LINQ to Entities查询中构造实体或复杂类型'MyModel.Team'." 当我导航到Team/Index/{id}页面时.有人能指出我做的错误吗？

控制器:

public ActionResult Index(int id)
    {
        IQueryable<Team> teams = teamRepository.GetTeamByPersonID(id);   
        return View("Index", teams);
    }

库:

public IQueryable<Team> GetTeamByPersonID(int id)
    {
        return from t in entities.Teams
               join d in entities.Departments
                on t.TeamID equals d.TeamID
               where (from p in entities.Person_Departments
                      join dep in entities.Departments
                      on p.DepartmentID equals dep.DepartmentID
                      where p.PersonID == id
                      select dep.TeamID).Contains(d.TeamID)
               select new Team
               {
                   TeamID = t.TeamID,
                   FullName = t.FullName,
                   ShortName = t.ShortName,
                   Iso5 = t.Iso5,
                   DateEstablished = t.DateEstablished,
                   City = t.City,
                   CountryID = …

我在这种格式的文件夹中有很多文件

constant_blah_blah_blah.png

如何用空格替换下划线并使用PowerShell从中删除constant_？

提前致谢.

我想格式化TextBoxes中显示的DateTime,没有时间和格式:2011年1月1日,而不是显示和编辑方案的默认01/01/2011.

我已经使用DateTime的以下模板来使用datepicker.我可以在某种程度上包括格式吗？

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime?>" %>
<%: Html.TextBox("",ViewData.TemplateInfo.FormattedModelValue, new { @class = "text-box single-line" }) %>

提前致谢.

我在视图中使用以下代码,我试图在最后使用附加参数添加撤销链接但我收到以下错误:

System.ArgumentException:参数字典包含'MaxMe2.Controllers.TeamController中方法'System.Web.Mvc.ActionResult Withdraw(Int32,Int32)'的非可空类型'System.Int32'参数'personID'的空条目".可选参数必须是引用类型,可空类型,或者声明为可选参数.

<% if(Model.departmentsDisplayCheck) {%>
<table>
    <tr>         
        <th>Name</th>
        <th>Type</th>
        <th>Status</th> 
    </tr>

<% foreach (var dep in Model.departmentsList){ %>

    <tr>
        <td><%: Html.ActionLink(dep.Name, "Details", "Department", new { id=dep.DepartmentID}, null) %></td>
        <td><%: dep.DepartmentType.Type %></td>
        <td><%: dep.DepartmentStatus.Status %></td>
        <td><%: Html.ActionLink("Withdraw", "Withdraw", "Team", new { id = Model.personalInfo.PersonID, dep = dep.DepartmentID}, null)%></td>
    </tr>
<% } %>

我试图调用的控制器方法是这样的:

public ActionResult Withdraw(int personID, int departmentID)
    {
        .....
    }

我怎样才能做到这一点？提前致谢!
