问题描述
更改 mvc 项目的命名空间后遇到以下问题:
I ran into the following problem after changing the namespace for my mvc project:
找到多个与名为Home"的控制器匹配的类型.如果为此请求提供服务的路由 ('{controller}/{action}/{id}') 没有指定命名空间来搜索与请求匹配的控制器，就会发生这种情况.如果是这种情况，请通过调用采用namespaces"参数的MapRoute"方法的重载来注册此路由.
对Home"的请求已找到以下匹配的控制器:
The request for 'Home' has found the following matching controllers:
oldns.Controllers.HomeController
oldns.Controllers.HomeController
newns.Controllers.HomeController
newns.Controllers.HomeController
关于此错误还有其他已回答的问题，但涵盖了其他原因:

推荐答案
经过一番研究，我发现原因是旧的 mvc app dll 残留在 bin 文件夹 (binoldns.dll) 中.清洁并没有清除它.我手动删除了bin目录的内容，然后一切正常.
After doing some research, I found that the cause was the old mvc app dll remaining in the bin folder (binoldns.dll). Clean was not clearing it out. I manually deleted the contents of the bin directory and then all was well.
