如何在MVC 5中添加約束解析器？

Question

我有一個ASP.NET MVC 5項目如下：

DefaultInlineConstraintResolver resolver = new DefaultInlineConstraintResolver(); 
resolver.ConstraintMap.Add("notetype", typeof(EnumConstraint<NoteType>)); 
RouteTable.Routes.MapMvcAttributeRoutes(resolver); 
GlobalConfiguration.Configuration.MapHttpAttributeRoutes(resolver); 

在最後一行解析器未在MapHttpAttributeRoutes接受。我怎樣才能做到這一點？

試試這個

DefaultInlineConstraintResolver resolver = new DefaultInlineConstraintResolver(); 
resolver.ConstraintMap.Add("notetype", typeof(EnumConstraint<NoteType>)); 
RouteTable.Routes.MapMvcAttributeRoutes(resolver); 
GlobalConfiguration.Configuration.MapHttpAttributeRoutes(new HttpRouteBuilder(resolver));
