所以我现在的问题是，当我提交以下表格时，我无法将我的模型放入我的控制器中。我试图让BillingCodes（这是一个BillingCodeObjects列表）中的项循环并显示。我删除了一些与这种情况无关的代码，使其更简短易读。
以下是我的观点代码......
@using (Html.BeginForm("SubmitTimesheet", "Timesheet", FormMethod.Post))
{
foreach (var item in Model.BillingCodes)
{
<div class="button-padding">
<a class="btn btn-large btn-danger btn-block billCodeBtn">
<div class="btnText">@item.Name</div>
<div class="btnTime">@item.TotalHours</div>
<i class="icon-chevron-down billCodeIconUp billCodeIcon"></i>
<i class="hidden icon-chevron-up billCodeIconDown billCodeIcon"></i>
</a>
<div class="content" >
<div class="row timeEntry">
<p></p>
<div class="col-12 col-lg-2">
Enter Time:
<div class="row">
<div class="col-12">
@Html.DropDownListFor(model => item.EnterTimeHours, new SelectList(new[] {
new { Value = "0", Text = "0" },
new { Value = "1", Text = "1" },
new { Value = "2", Text = "2" },
new { Value = "3", Text = "3" },
new { Value = "4", Text = "4" },
new { Value = "5", Text = "5" },
new { Value = "6", Text = "6" },
new { Value = "7", Text = "7" },
new { Value = "8", Text = "8" },
new { Value = "9", Text = "9" },
new { Value = "10", Text = "10" },
new { Value = "11", Text = "11" },
new { Value = "12", Text = "12" },
}, "Value", "Text")) <b>:</b>
@Html.DropDownListFor(model => item.EnterTimeMinutes, new SelectList(new[] {
new { Value = "0", Text = "00" },
new { Value = "15", Text = "15" },
new { Value = "30", Text = "30" },
new { Value = "45", Text = "45" },
}, "Value", "Text"))
</div>
</div>
</div>
<div class="col-lg-2"></div>
<div class="col-lg-1"></div>
<div class="control-group col-12 col-lg-2">
<label class="checkbox">
Billable @Html.CheckBoxFor(model => item.Billable)
</label>
</div>
<div class="col-12 col-lg-2">
Enter Memo:
<div class="row">
<div class="col-12">
@Html.TextAreaFor(model => item.Comment)
</div>
</div>
以下是我的控制器的一些代码：
public class TimesheetController : Controller
{
//
// GET: /Timesheet/
public ActionResult Index()
{
string getBillingCodeUrl ="";
//SOME CODE REMOVED FOR LENGTH / READABILITY
foreach (var entryItem in timePeriod.TimeEntries[0].EntryCollection)
{
foreach (var billingItem in billingCodeList.BillingCodes)
{
if (entryItem.BillingCode == billingItem.Name)
{
//update record in billingItem with data from entryItem
billingItem.Comment = entryItem.Comment;
billingItem.Billable = entryItem.Billable;
billingItem.TotalHours = entryItem.Hours;
}
}
}
return View(billingCodeList);
}
[HttpPost]
public void SubmitTimesheet(BillingCodeList model)
{
string uri = "";
foreach (var billingCode in model.BillingCodes)
{
//do stuff with each of these
}
}
}
}
最后，这是模型中的信息：
public class BillingCodeList
{
public List<BillingCodeObj> BillingCodes;
}
public class BillingCodeObj
{
public string Name { get; set; }
public decimal TotalHours { get; set; }
public decimal EnterTimeHours { get; set; }
public decimal EnterTimeMinutes { get; set; }
public bool Billable { get; set; }
public string Comment { get; set; }
public BillingCodeObj(string name, decimal hours)
{
this.Name = name;
this.TotalHours = hours;
}
public BillingCodeObj()
{
}
}
这是返回表单时调试本地的图片。

您正在对视图进行操作，因此输入元素应该在某处发布值，如下所示：
name="BillingCodes[0].EnterTimeHours"，name="BillingCodes[0].EnterTimeMinutes"您可以在网络标签中检查Chrome开发者工具上的请求（CTRL + SHIFT + C）
或只是查看来源。如果是这种情况，则表示您正在提交多个BillingCodeObj对象。你必须有一个接收它的控制器。
查看源代码，因为这可以极大地帮助您了解幕后发生的事情。
在你的控制器上试试这个：
[HttpPost]
public void SubmitTimesheet(IEnumerable<BillingCodeObj> billingCodes){
}
您也可以（出于调试目的）执行
public void SubmitTimesheet(FormCollection form){}
并检查表单在调试时的填充方式。
在评论和提供更多代码之后 将您的观点更改为：
@using (Html.BeginForm("SubmitTimesheet", "Timesheet", FormMethod.Post))
{
@Html.EditorFor(m=>m.BillingCodes)
}
在EditorTemplates / BillingCodeObj.cshtml中创建一个新的cshtml：
@model BillingCodeObj
<div class="button-padding">
<a class="btn btn-large btn-danger btn-block billCodeBtn">
<div class="btnText">@Model.Name</div>
<div class="btnTime">@Model.TotalHours</div>
<i class="icon-chevron-down billCodeIconUp billCodeIcon"></i>
<i class="hidden icon-chevron-up billCodeIconDown billCodeIcon"></i>
</a>
<div class="content" >
<div class="row timeEntry">
<p></p>
<div class="col-12 col-lg-2">
Enter Time:
<div class="row">
<div class="col-12">
@Html.DropDownListFor(model => model.EnterTimeHours, new SelectList(new[] {
new { Value = "0", Text = "0" },
new { Value = "1", Text = "1" },
new { Value = "2", Text = "2" },
new { Value = "3", Text = "3" },
new { Value = "4", Text = "4" },
new { Value = "5", Text = "5" },
new { Value = "6", Text = "6" },
new { Value = "7", Text = "7" },
new { Value = "8", Text = "8" },
new { Value = "9", Text = "9" },
new { Value = "10", Text = "10" },
new { Value = "11", Text = "11" },
new { Value = "12", Text = "12" },
}, "Value", "Text")) <b>:</b>
@Html.DropDownListFor(model => model.EnterTimeMinutes, new SelectList(new[] {
new { Value = "0", Text = "00" },
new { Value = "15", Text = "15" },
new { Value = "30", Text = "30" },
new { Value = "45", Text = "45" },
}, "Value", "Text"))
</div>
</div>
</div>
<div class="col-lg-2"></div>
<div class="col-lg-1"></div>
<div class="control-group col-12 col-lg-2">
<label class="checkbox">
Billable @Html.CheckBoxFor(model => model.Billable)
</label>
</div>
<div class="col-12 col-lg-2">

您的视图的类型为BillingCodeList，但您尝试将List<BillingCodeObj>发送给您在控制器中的操作。
尝试按如下方式更改操作：
[HttpPost]
public void SubmitTimesheet(BillingCodeList model)
{
string uri = "";
foreach (var billingCode in model.BillingCodes)
{
//do stuff with each of these
}
}

编辑：在将模型发送到视图之前，您似乎没有将BillingCodeList的列表元素初始化为new List<BillingCode>()。或者是你？
