我正在尝试使用
Steve Sanderson’s blog post来编辑我的ASP MVC 3视图中的可变长度列表.该项目构建良好,但是无论何时渲染部分视图,该程序会在使用(Html.BeginColletionItem()行中冒出此错误：
AccessViolationException was unhandled Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
这是一个完整例外的屏幕截图

我已经能够在现在使用的解决方案之外的项目中工作,所以它显然与这个工作区中的一些dll有关.现在我在我的工资级别以上,因为我不确定如何调试这样的东西.以下是Visual Studio抛出AccessViolationException之前由WinDbg标识的异常.在抛出异常之间有很多信息,如果任何人需要,请让我知道.

UPDATE
我现在收到一个稍微更详细的错误信息：
最后,通过如下所示切换到IIS Express,我仍然收到AccessViolationException.以下是我用于启用IIS进行调试的设置(在项目属性下)
这是错误消息
调用堆栈：
解决方法
似乎我比你需要更努力工作.
首先,使用for循环替换foreach,将索引的元素传递给编辑器模板.这将建立您的模板上下文.
<fieldset>
<legend>Relationship Codes</legend>
<table id="Experiment">
<thead>
<tr>
<th>Relationship Effective Date</th>
<th>Relationship Dist Code</th>
</tr>
</thead>
<tbody>
@for (var i = 0; i < Model.AgentRelationshipCodes.Count(); i++)
{
@Html.EditorFor(model => model.AgentRelationshipCodes[i])
}
</tbody>
</table>
<br/>
<a href="javascript:void(0)" class ="addCode">Add Another</a>
</fieldset>
然后创建一个名为AgentRelationshipCodes.cshtml的编辑器模板(在Views / Shared / EditorTemplates中)
@model Monet.Models.AgentRelationshipCodes
<tr>
<td>@Html.EditorFor(model => model.EffectiveDate,new { @class = "relCodeDate2" })</td>
<td>@Html.EditorFor(model => model.RelationshipId,maxlength = 3 })</td>
@Html.HiddenFor(model => model.ID)
@Html.HiddenFor(model => model.RelCodeOrdinal)
</tr>
这样就不再需要自定义的帮助者,而这些帮助者似乎是导致问题的原因.
最后,添加新元素 – 将字段集移动到部分：
<script>
$(document).ready(function() {
$(".addCode").click(function () {
$('#fieldset').load('@Url.Action("NewRelationshipCode",$('#fieldset').closest('form').serialize());
});
});
</script>
<div id="fieldset">
@Html.Partial("fieldset");
</div>
并从NewRelationshipCode操作方法返回fieldSet视图：
[HandleProcessCorruptedStateExceptions] public ViewResult NewRelationshipCode(Yourviewmodel model) { model.AgentRelationshipCodes.Add(new AgentRelationshipCodes()); return View("fieldset",model); }
