推荐答案

我得到的回答从我的同事:)之一。

I got the answer from one of my colleagues :) .

当我们调用的服务，MVC试图在指定的RegisterRoutes解决的路径。
因此，它试图找到具有该名称的控制器和具有名称相同该控制器内操作的方法。该决议忽略了与扩展的.asmx的路径。您可以通过添加下面的行RouteConfig.cs做到这一点：

When we invoke the service, the MVC tries to resolve the path as specified in RegisterRoutes. Hence it tries to find a controller with that name and a method with the name same as that of the operation inside that controller. The resolution, ignore the paths with .asmx extension. You can do that by adding the following line in RouteConfig.cs :

routes.IgnoreRoute("{*x}", new { x = @".*\.asmx(/.*)?" }); 

和它的工作。谢谢你。
