我有一个员工列表,所有员工都有另一个嵌套列表,称为DisplayList.

现在并非所有员工都拥有相同数量的DisplayField.所以我希望得到具有最高DisplayFields的那些,以便我可以将每个人都包含在显示器中.

目前我有以下内容: -

            int iMaxDisplayCount = 0;
        foreach (Employee employee in employeeList)
        {
            int iDisplayCount = employee.EmployeeDisplayCollection.Count;
            if (iDisplayCount > iMaxDisplayCount)
                iMaxDisplayCount = iDisplayCount;
        }

        var employees = employeeList.GroupBy(p => p.EmployeeDisplayCollection.Count == iMaxDisplayCount).Select(g => g.ToList());  
        foreach(var employeeHighList in employees)
        {
            foreach (var employee in employeeHighList) 
            {         

            }         
        } 

但是出于某种原因,我得到了employeeHighList中的所有员工,而不仅仅是拥有最高显示数量的员工.

我认为GroupBy不正确,但不知道它有什么问题.

任何帮助将非常感谢!

谢谢

我<asp:Label> 希望根据我传递给它的Generic对象进行填充.

目前我有以下代码: -

    private void PopulateEnglishQuestion(int questionId)
    {
        ReportQuestion reportQuestion = questionsBll.GetReportQuestions().Where(x=> x.ReportQuestionId == questionId).FirstOrDefault();
        PopulateLabels(reportQuestion);
    }

    private void PopulateTranslatedQuesiton(int questionId)
    {
        ReportQuestionTranslation reportQuestionTranslation = questionsBll.GetReportQuestionsTranslation().Where(x => x.QuestionId == questionId).FirstOrDefault();
        PopulateLabels(reportQuestionTranslation);
    }

    private void PopulateLabels<T>(T item)
    {
        lblQuestionTitle.Text = typeof (T) == typeof (ReportQuestion)
                                    ? ((ReportQuestion) (item)).ReportQuestionTitle
                                    : ((ReportQuestionTranslation) (item)).ReportQuestionTitleTrans; 
    }

如何让PopulateLabels方法正常工作？

我有2个重载方法,因为参数SecondVar有时可用,有时不可用: -

private void DoSomething(int FirstVar)
{
    int SecondVar = 0;
    DoSomething(FirstVar, SecondVar);
}

private void DoSomething(int FirstVar, int SecondVar)
{
    DoSomething(FirstVar, SecondVar);

    if(SecondVar > 0)
    {
       var a = GetList().Where(x=>x.FirstId == FirstVar && x.SecondId == SecondVar);
    }
    else
    {
       var a = GetList().Where(x=>x.FirstId == FirstVar);
    }

}

是否有可能在第二个重载的DoSomething中摆脱If子句？

谢谢你的帮助和时间

我有以下WebMethod: -

        [WebMethod(EnableSession = true)]
    public static void OpenReport(string reportName)
    {
        Report report = reportsBll.GetReports().FirstOrDefault(x => reportQuestion != null && x.Id == reportQuestion.ReportId);

        if (report != null) reportUrl = report.Url;
    }

现在我希望传递report.Url到这个Jquery方法: -

    $('.ReportButton').click(function () {
    var args = { reportName : '' };

    $.ajax({
        type: "POST",
        url: "ReportsByQuestionsDetails.aspx/OpenReport",
        data: JSON.stringify(args),
        contentType: "application/json;charset=utf-8;",
        success: function (data) {
            alert('success');
            document.location.href = reportUrl;
        },
        error: function () {
        }
    });
});

如何将reportUrl从WebMethod传递给Jquery？

谢谢你的帮助和时间

我有以下cshtml表单

@using (Html.BeginForm(Html.BeginForm("Create", "UserRole", Model, FormMethod.Post)))
{
   @Html.AntiForgeryToken()
   @Html.ValidationSummary(true)

   <fieldset>
       <legend>Role</legend>

       <div class="editor-label">
           @Html.Label(Model.User.UserName)
       </div>
       <div class="editor-field">
           @Html.CheckBoxList(Model.CheckboxList)
       </div>

       <p>
           <input type="submit" value="Create" />
       </p>
   </fieldset>
}

我希望在我的操作中获取Model.CheckboxList选择的项目.

我的控制器中有以下创建操作

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create(UserRoleViewModel userRoleViewModel)
    {
        if (ModelState.IsValid)
        {
            //_context.Role.Add(role);
            //_context.SaveChanges();
            //return RedirectToAction("Index");
        }

        return View(viewModel);
    }

但是viewModel.CheckboxList为0.

如何将复选框列表的选定值以及Model.User传递给Controller Action？

我的ViewModel看起来像这样: -

    public User User { get; set; }
    public IEnumerable<Role> RoleList { get; set; }

    public List<UserRoleViewModel> UserList { get; set; }

    public IEnumerable<SelectListItem> CheckboxList { get; set; } …

我正在尝试使用JSON在部分视图中显示Google地图.我已经在普通视图中尝试了代码,它工作得很好.

我有以下内容: -

部分视图ShowMap.cshtml

@using Microsoft.Web.Helpers

<script src="~/Scripts/jquery-1.8.3.min.js"></script>
<div class="experienceRestrictedText">
    @Maps.GetGoogleHtml("1, Redmond Way, Redmond, WA", width: "400", height: "400")
</div>

Index.cshtml(启动部分视图的位置)

    $('.modal_link_map').on('click', function (e) {
        $('.modal_part').show();
        var id = $(this).attr('data-id');
        var context = $('#tn_select').load('/Experience/ShowMap?id=' + id, function () {
            initSelect(context);
        });
        e.preventDefault();
        return false;
    });

控制器动作如下: -

        public ActionResult ShowMap()
        {
        _ItemID = Convert.ToInt32(Request.QueryString["id"]);

        viewModel.ExperienceViewModel.Experience =     unitOfWork.ExperienceRepository.GetByID(_ItemID);

        return PartialView(viewModel);
        }

我需要包含其他任何内容才能使用此地图吗？

我有以下jquery对象: -

        (function ($) {
            var menu = [{
                title: Main1",
                href: "/"
            }, {
                title: "Main2",
                href: "/main2",
                items: [{
                    title: "SubMain2_1",
                    href: "/subMain2_1"
                }, {
                    title: "SubMain2_2",
                    href: "/subMain2_2"
                }]
            }, {
                title: "Main3",
                href: "/main3",
                items: [{
                    title: "SubMain3_1",
                    href: "/subMain3_1"
                }, {
                    title: "SubMain3_2",
                    href: "/subMain3_2",
                    items: [{
                        title: "SubSubMain3_1",
                        href: "/SubSubMain3_2"
                    }, {
                        title: "SubSubMain3_2",
                        href: "/subSubMain3_2"
                    }]
                }, {
                    title: "SubMain3_3",
                    href: "/subMain3_3"
                }]
            }, {
                title: "Main4",
                href: "/main4"
            }];
        });

我希望把它变成

   <ul> …
