Question

我是MVC的初学者，并尝试将集合发布到控制器操作，但在控制器中，它显示集合的计数= 0。我尝试了很多不同的方法但没有成功。

我有两个视图模型（PatientViewModel，PatientTestViewModel）和内部患者视图模型，我有一个名为PatientTestVM的PatientTestViewModel集合。下面是代码...

public class PatientViewModel
{
    private MHUContext ctx = new MHUContext();
    public patient _Patient { get; set; }
    public string MhuKey { get; set; }
    public lkp_child _LkpOccupation { get; set; }
    public List<PatientTestViewModel> PatientTestVM { get; set; }
}

并且有一个名为Patient.cshtml的

的PatientViewModel视图

@using Shared
@model Shared.PatientViewModel
@{
ViewBag.Title = "Patient";
}
<section class="well">
@using (Html.BeginForm("CreatePatient", "Patients", FormMethod.Post, new { id = "patient-main-form" }))//new { ReturnUrl = ViewBag.ReturnUrl }))
{

...一些代码，然后我调用部分视图来呈现PatientTestViewModel的集合

<div class="accordion panel-group" id="accordion-pat-mh">
    <div class="accordion-group panel panel-primary">
        <div class="accordion-heading panel-heading">
            <h3 class="panel-title">
                <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion-pat-mh" href="#mh">Medical History</a>
            </h3>

        </div>
        <div id="mh" class="accordion-body panel-body collapse in">
            <div class="accordion-inner ">
                @for (int i = 0; i < Model._PatientTestVM.Count; i++)
                {
                    Html.RenderPartial("_PatientTestTile", Model._PatientTestVM[i]);
                }

            </div>
        </div>
    </div>
</div>

}

这是局部视图

@model Shared.PatientTestViewModel
<div>
    <div class="col-sm-12 div_@(Model.PatientTestKey)">
        <div class=" form-horizontal form-widgets col-sm-2">
            <div class="form-group">
                <label style="font-weight:normal; text-align:center;" class="control-label col-sm-10 col-md-8" for="">@Model._PatientTest.lkp_child.name</label>
            </div>
        </div>
        <div class=" form-horizontal form-widgets col-sm-4">
            <div class="form-group">
                <label style="font-weight:normal; text-align:center;" class="control-label col-sm-10 col-md-8">@Model._PatientTest.date_created</label>
            </div>
        </div>
        <div class=" form-horizontal form-widgets col-sm-3">
            <div class="form-group">
                <div class="col-sm-10 col-md-8">
                    <button type="button" class="k-button k-state-default btnEdit_@(Model.PatientTestKey)">Edit</button>
                    <button type="button" class="k-button k-state-default btnDelete_@(Model.PatientTestKey)">Delete</button>
                </div>
            </div>
        </div>
<div class=" form-horizontal form-widgets col-sm-3">
        <div class="form-group">
            <div class="col-sm-10 col-md-8">
                @Html.EditorFor(m => m._PatientTest.test_status)
                <span> Result Received</span>
            </div>
        </div>
    </div>

现在当我提交from时，它不会在patienttestviewmodel的集合中显示任何记录

public ActionResult CreatePatient(PatientViewModel PostedPatientVM)
{
    if (ModelState.IsValid)
    {

postedPatientVM.PatientTestVM.Count = 0

有关此计数为零的任何帮助/建议？请注意这是编辑记录的情况（我收集了数据，但回发时，收集中的数据变为空）

无法将收集数据发布到Controller操作
