UpdateModel的ASP.NET MVC 2问题

我正在尝试将updatemodel(myItem,formcollection)与asp.net mvc 2一起使用,但它在下面的堆栈跟踪中失败了。

   at System.Web.Mvc.FormCollection.GetValue(String name)
   at System.Web.Mvc.DefaultModelBinder.BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
   at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider)
   at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, IValueProvider valueProvider)
   at Stormbreaker.Dashboard.Controllers.DashboardController`1.Update(FormCollection collection) in D:\Projects\SVN\Stormbreaker\trunk\Stormbreaker.Dashboard\Controllers\DashboardController.cs:line 23
   at lambda_method(ExecutionScope , ControllerBase , Object[] )
   at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters)
   at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary`2 parameters)
   at System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClassd.<InvokeActionMethodWithFilters>b__a()
   at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter(IActionFilter filter, ActionExecutingContext preContext, Func`1 continuation)

我的行动如下:

    [AcceptVerbs(HttpVerbs.Post)]
    [ValidateInput(false)]
    public ActionResult Update(FormCollection collection) {
        UpdateModel(CurrentItem, collection);
        CurrentItem = (T)_repository.Update(CurrentItem);
        return RedirectToAction("edit", new { pagePath = CurrentItem.UrlSegment });
    }

...我的表格看起来像这样:

<% using (Html.BeginForm("Update","Dashboard", FormMethod.Post, new { name = "editForm" } )) %>
<% { %>
    <div>
        <%=Html.EditorForModel() %>
        <input type="submit" value="Save" />
    </div>            
<% } %>

这是MVC 2 RC中确认的错误。如果您有the MVC source,则可以从FormCollection.GetValue()中删除String.IsNullOrEmpty()检查,重新编译和重新部署。 FormCollection类位于 src \ SystemWebMvc \ Mvc \ FormCollection.cs 。团队意识到了这一点,并计划在下一次预览中进行修复。
