各个领域的ASP.NET MVC4名单 [英] ASP.NET MVC4 List of all areas

问题描述

我在我创建多个区域的ASP.NET应用程序MVC4，是有办法，我可以找出是present地区，他们的名字以编程的数量。

I have an ASP.NET MVC4 application in which I am creating multiple areas, is there a way I can find out programmatically the number of areas that are present and their names.

推荐答案

的 AreaRegistration.RegisterAllAreas（）; 注册与每个区域路线 DataTokens [区] 其中值是区域的名称

The AreaRegistration.RegisterAllAreas(); registers each area route with the DataTokens["area"] where the value is the name of the area.

所以，你可以从已注册的区域名称 RouteTable

So you can get the registered area names from the RouteTable

var areaNames = RouteTable.Routes.OfType<Route>()
    .Where(d => d.DataTokens != null && d.DataTokens.ContainsKey("area"))
    .Select(r => r.DataTokens["area"]).ToArray();

如果您正在寻找的 AreaRegistration 本身，你可以使用反射来获得从 AreaRegistration 派生的类型的assambly。

If you are looking for the AreaRegistration themselves you can use reflection to get types which derives from AreaRegistration in your assambly.
