阿拉法特的链接导致我这似乎工作的一个答案。在web.config文件中的 部分中，添加：

Yasser's link led me to an answer which seems to work. In the web.config file section, add:

   <httpErrors errorMode="Custom" existingResponse="Replace">
<remove statusCode="404" />
<error statusCode="404" responseMode="ExecuteURL" path="/Error/PageNotFound" />
 </httpErrors>

You can then create a router and controller for this path, and it all seems to work. Is it really that simple?
