MVC 4.0 String未被识别为有效的布尔值

Question

我有一个razor 2.0表单，可以在本地完美运行。我已经验证了MVC，Razor和助手的产品都是最新版本。我在每个使用@Html.BeginForm不同参数的页面上都会收到此异常。只要没有使用表单助手，MVC页面似乎工作正常：

这个形式很简单：

我原本怀疑dll版本错误或缺失。所有MVC组件都应该在bin文件夹中，我已经验证了这一点（至少是顶级dll）

This project uses a combination of ASP pages and MVC Views, and previously was working with webforms 1.0 and MVC 2.0. The application is setup as an application under the default website. I've seen lots of variations with this same exception but most came down to syntax errors in the form helpers. This seems to be more environmentally related. Any help would be greatly appreciated!

Answer 1

这个问题来自web.config错误，具体来说，有以下两行：

<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />

第二行在具有无效的布尔值时被破坏，如：

<add key="UnobtrusiveJavaScriptEnabled" value="none" />

Answer 2

我遇到了同样的问题，但这是因为我忘了将模型对象传递到视图页面。

我刚过return view();

我改为return view(new ModelObject());
