POST控制器操作方法的LIST返回计数为0

Question

这是一个简单的问题，我已经查看了所有相关的答案(有很多)，并将我的代码与之进行了比较，我看不出哪里出了问题。

控制器

[HttpGet]public ActionResult PatInformation(长id){if(ModelState.IsValid){var patient=db.tblPatients.Find(id)；PatientViewModels patientVM=_mapper.Map<PatientViewModels>(患者)；return视图(patientVM)；}return RedirectToAction("索引")；}[HttpPost][ValidateAntiForgeryToken]公共操作结果PatientInformation(PatientViewModels模型){if(！ModelState.IsValid){return视图(模型)；}tblPatienttblPatient=db.tblPatients.Find(model.PPatientID)；tblPatient.Forename1=型号。前言1；tblPatient.Surname=型号。姓数据库。Entry(tblPatient).State=EntityState.Modified；数据库。SaveChanges()；PatientViewModels patientsVM=_mapper.Map<PatientViewModels>(tbl患者)；return View("PatientInformation"，patientVM)

ViewModel

当我发布带有tblTumours List的控制器时，总是返回as count=0。我确信这是一个简单的解决方案，但我就是看不到。

希望有人能帮上忙，请坦白，因为我刚开始是一名开发人员，并继承了这一点。谢谢

试试这个

@using (Html.BeginForm("PatientInformation", "YourController", FormMethod.Post))
{
<table id="tblTumours" class="table">
<thead>
<tr>
<th>Tumour Id</th>
<th>ICD03 Site</th>
<th>ICD10 Site</th>
<th>Morphology</th>
<th>Behaviour</th>
<th>Diagnosis</th>
<th>Method</th>
<th>Status</th>
<th>Final Stage / Complate</th>
</tr>
</thead>
<tbody>
@for (int i = 0; i < Model.tblTumours.Count; i++)
{
<tr class="table-row" data-href="@Url.Action(" TumourInformation", "Tumours" , new { tumourId=Model.tblTumours[i].TumourID, patientId=Model.PatientID })">
<td class="pt-3-half" hidden="true">@Html.TextBoxFor(m => Model.tblTumours[i].TumourID, new { Class = "form-control" })</td>
<td class="pt-3-half">@Html.TextBoxFor(m => Model.tblTumours[i].TumourNo, new { Class = "form-control" })</td>
<td class="pt-3-half">@Html.HiddenFor(m => Model.tblTumours[i].ICD03, new { Class = "form-control" })</td>
<td class="pt-3-half">@Html.TextBoxFor(m => Model.tblTumours[i].ICD03, new { Class = "form-control" })</td>
<td class="pt-3-half">@Html.TextBoxFor(m => Model.tblTumours[i].ICD10, new { Class = "form-control" })</td>
<td class="pt-3-half">@Html.TextBoxFor(m => Model.tblTumours[i].tblMorphology.morphology_code, new { Class = "form-control" })</td>
<td class="pt-3-half">@Html.TextBoxFor(m => Model.tblTumours[i].tblBehaviour.BehaviourCode, new { Class = "form-control" })</td>
<td class="pt-3-half">@Html.TextBoxFor(m => Model.tblTumours[i].DateOfDiag, new { Class = "form-control" })</td>
<td class="pt-3-half">@Html.TextBoxFor(m => Model.tblTumours[i].Metastases, new { Class = "form-control" })</td>
<td class="pt-3-half"><span class="badge badge-warning">@Html.TextBoxFor(m => Model.tblTumours[i].TumourStatus, new { Class = "form-control" })</span></td>
<td class="pt-3-half">@Html.TextBoxFor(m => Model.tblTumours[i].StageGrade, new { Class = "form-control" })</td>
</tr>
}
