AccessViolationException未处理

我正在尝试使用Steve Sanderson的博客文章来编辑ASP MVC 3视图中的可变长度列表。 该项目构建正常，但无论何时呈现局部视图，程序都会在using(Html.BeginColletionItem()行中出现此错误：

 AccessViolationException was unhandled Attempted to read or write protected memory. This is often an indication that other memory is corrupt. 

这是完整例外的屏幕截图

完整的堆栈跟踪如下

部分视图

 @model Monet.Models.AgentRelationshipCodes @using (Html.BeginCollectionItem("AgentRelationshipCodes")) @*Exception thrown here*@ {  @Html.EditorFor(model => model.EffectiveDate, "NullableDate", new { @class = "relCodeDate2" }) @Html.EditorFor(model => model.RelationshipId, "NullableDate", new { @class = "relDistCode1", maxlength = 3 }) @Html.HiddenFor(model => model.ID) @Html.HiddenFor(model => model.RelCodeOrdinal)  } 

视图

   $(document).ready(function() { $(".addCode").click(function () { $.ajax({ url: '@Url.Action("NewRelationshipCode", "AgentTransmission")', dataType: 'html', cache: false, success: function (html) { console.log(html); $("#Experiment > tbody").append(html); } }) }); });  . . 
 
Relationship Codes
  @foreach (var item in Model.AgentRelationshipCodes) { @Html.Partial("AddRelationshipCodePartial", item) } 
 
 
 
Relationship Effective Date
 
Relationship Dist Code
 
 
 
 
 
 Add Another  

调节器

  [HandleProcessCorruptedStateExceptions] public ViewResult NewRelationshipCode() { return View("AddRelationshipCodePartial", new AgentRelationshipCodes()); } 

AgentRelationshipCodes

 namespace Monet.Models { using System; using System.Collections.Generic; public partial class AgentRelationshipCodes { public int ID { get; set; } public int RelCodeOrdinal { get; set; } public string RelationshipId { get; set; } public Nullable EffectiveDate { get; set; } public System.DateTime LastChangeDate { get; set; } public string LastChangeId { get; set; } public virtual AgentTransmission AgentTransmission { get; set; } } } 

编辑

我已经能够在我正在使用的解决方案之外的项目中使用该演示，因此它显然与此工作空间中的某些dll有关。 然而，现在我高于我的薪水，因为我不确定如何调试这样的东西。 以下是在Visual Studio抛出AccessViolationException之前由WinDbg标识的exception。 抛出exception之间有很多信息，如果有人需要，请告诉我。

UPDATE

通过在项目的Debuggers菜单中选择“Native Code”选项

我现在收到一个稍微更详细的错误消息：

最后，通过切换到IIS Express，如下所示，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：

在我看来，你的工作比你需要的更努力。

首先，用for循环替换foreach，将索引元素传递给编辑器模板。 这将建立您的模板上下文。

 
 
Relationship Codes
  @for (var i = 0; i < Model.AgentRelationshipCodes.Count(); i++) { @Html.EditorFor(model => model.AgentRelationshipCodes[i]) } 
 
 
 
Relationship Effective Date
 
Relationship Dist Code
 
 
 
 
 
 Add Another  

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  @Html.EditorFor(model => model.EffectiveDate, "NullableDate", new { @class = "relCodeDate2" }) @Html.EditorFor(model => model.RelationshipId, "NullableDate", new { @class = "relDistCode1", maxlength = 3 }) @Html.HiddenFor(model => model.ID) @Html.HiddenFor(model => model.RelCodeOrdinal)  

这消除了对导致问题的自定义助手的需要。

最后，添加新元素 – 将字段集移动到部分：

  
 @Html.Partial("fieldset");  

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); }
