我正在尝试将模型中的简单列表发布回控制器。它正确呈现，但在发布时它总是空的。我注意到当我使用 @Html.Hidden 的 id 和 name 是不同的例如 id 变成TestExceptionDisplay_[0]__Exception和 name 变成TestExceptionDisplay[0].Exception. 所以我使用一种输入类型，并尝试按照它喜欢的方式呈现，但它不起作用。我尝试了部分视图，编辑器模板，似乎没有任何效果。TestException Display 是一个非常简单的对象列表，称为 public List<RunLogEntryTestExceptionDisplay> TestExceptionDisplay { get; set; }
public class RunLogEntryTestExceptionDisplay
{
public string Exception { get; set; }
}
视图中的片段使用 for 循环呈现列表，列表呈现正常，但在后 TestExceptionDisplay 始终为 NULL：
@if (Model.TestExceptionDisplay != null)
{
for (var i = 0; i < Model.TestExceptionDisplay.Count; i++)
{
<tr>
<td>
@Model.TestExceptionDisplay[i].Exception
@*@Html.HiddenFor(m => m.TestExceptionDisplay[i].Exception)*@
<input name="RunLogEntry.TestExceptionDisplay_[@i]__Exception" type="hidden" value="@Model.TestExceptionDisplay[i].Exception" />
</td>
</tr>
}
}
或者这甚至不适用于发布时的编辑器模板
@if (Model.TestExceptionDisplay != null)
{
@Html.EditorFor(x => x.TestExceptionDisplay)
}
Shared\EditorTemplates 中的编辑器模板，其确切名称为 RunLogEntryTestExceptionDisplay
@model RunLog.Domain.Entities.RunLogEntryTestExceptionDisplay
<div>
@Html.EditorFor(x => x.Exception)
@Html.HiddenFor(x => x.Exception)
</div>
呈现的 HTML 如下所示，我没有复制整个列表，请不要让 ID 和名称看起来以不同的命名约定呈现。如果我使用编辑器模板或 for 循环，这两种情况都会发生。谢谢
<input id="TestExceptionDisplay_9__Exception" name="TestExceptionDisplay[9].Exception" type="hidden" value=""1404 TestException - Parameters:Unable to calculate result, assay is not calibrated for Assay Number (135), Assay Version (5), Track (1), Lane (2), and Reagent Lot Number (26600LI06)"" />
