在过去的 24 小时里，我一无所知。我有一个模型，其中填充了一个集合对象并将其渲染到视图中。一切渲染和回发都很好，当我将表单回发到控制器时，列表 TestExceptionDisplay 为空/null。请帮忙，这让我发疯了，我尝试了几种不同的方法，但现在一无所知。

基本上在视图的末尾有一个 foreach 循环，我在其中呈现 TestExceptionDisplay 属性，我确实为表单集合维护一个索引，以便在发布时将其取回，但无济于事，它总是空的。它渲染得很好，每个项目都使用正确的索引正确显示。 

public class RunLogEntryTestExceptionDisplay
{
        public string Exception { get; set; }

}


@model RunLog.Domain.Entities.RunLogEntry
@{
    ViewBag.Title = "Create";
    Layout = "~/Views/Shared/_Layout.cshtml";

我相信您最好让 MVC 进行实际迭代并使用索引命名（根据需要），以便稍后绑定已发布的元素。

为此，我建议创建一个编辑器模板，并使用@Html.EditorFor(m => m.TestExceptionDisplay).

与此处所做的类似：MVC 3 - List<> Model 的编辑器模板

并让您的编辑器模板只呈现单个项目（意思是，它的模型将是TestExceptionDisplay类型，而不是整体IEnumerable）。MVC 将为您处理迭代，并为每个项目正确编号。
