.NET MVC - 系统无法找到指定的路径

Question

昨天我将我的网站从c：\ development \ project \部署到c：\ inetpub \ wwwroot \ virtualdir \（同一个pc）。它工作了一段时间，我可以通过http://computername/virtualdir/访问该网站。

但今天早上，每个人都有一个错误：系统找不到指定的路径。

无法找到指定的路径是什么？/virtualdir/bin /包含System.Web.Mvc.Dll程序集...另外，部署项目已将其标记为依赖项，因此我在安装过程中确实包含了它，它如何突然更改？

Answer 1

它找到一个System.Web.Mvc就好了，因为你可以在堆栈跟踪看到：

System.Web.Mvc.MvcHandler.ProcessRequest(HttpContextBase httpContext) +128 

什么似乎正在发生的事情是ControllerTypeCache，当试图列举所有引用以查找控制器的assmeblies时，无法找到被另一个引用的程序集。

对于通过搜索来到此问题的其他人，可能会导致该错误消息的另一个配置错误是，如果您的虚拟目录配置中没有为“asnet_isapi.dll”创建的通配符映射。

要创建映射：

• 打开虚拟目录的属性。
• 在“虚拟目录”选项卡，单击“配置”按钮
• 点击“插入”，并浏览到相应的.NET版本的“ASPNET_ISAPI.DLL”文件
• 取消选中“验证文件是否存在”复选框
