[英]Receiving error page when publishing new view pages MVC 5 to IIS 8.5 , works fine debugging on local
Server Error in '' Application. ''应用程序中的服务器错误。 After turning off customErrors. 关闭customErrors之后。 Receiving the below on two new view pages, i created the views, they work fine when debugging on my local. 在两个新的视图页面上收到以下内容后,我创建了视图,在本地调试时它们可以正常工作。 The views are cshtml, from iEnumerable models, returning a toList() using currentURL Request.URL.AbsoluteURi in the view which might be the problem? 视图是来自iEnumerable模型的cshtml,使用视图中的currentURL Request.URL.AbsoluteURi返回toList()可能是问题所在? I've denied annonymous authentication, enabled windows auth. 我已拒绝匿名身份验证,已启用Windows身份验证。

Solved by changing the if statement query to ToList() 通过将if语句查询更改为ToList()来解决
rather than just converting toList at end of controller, i had to make sure the if statements were using toList() as well 而不是仅在控制器末尾转换toList,我必须确保if语句也使用toList()
