我需要寻找特定类型的所有组件在一个网站或Windows应用程序，有一个简单的方法来做到这一点？怎么样控制器工厂ASP.NET MVC看起来所有组件的控制器。

I need to look for specific types in all assemblies in a web site or windows app, is there an easy way to do this? Like how the controller factory for ASP.NET MVC looks across all assemblies for controllers.

感谢。

推荐答案

有两个步骤来实现这一点：

There are two steps to achieve this:

的 AppDomain.CurrentDomain.GetAssemblies（）为您提供了在当前应用程序域中加载的所有程序集。 的组装类提供了一个 GetTypes（）方法到特定组件内检索所有类型。 The AppDomain.CurrentDomain.GetAssemblies() gives you all assemblies loaded in the current application domain. The Assembly class provides a GetTypes() method to retrieve all types within that particular assembly.

因此​​您code可能是这样的：

Hence your code might look like this:

foreach (Assembly a in AppDomain.CurrentDomain.GetAssemblies())
{
    foreach (Type t in a.GetTypes())
    {
        // ... do something with 't' ...
    }
}

要查找特定类型（如实现一个给定的接口，从一个共同的祖先或任何继承），你必须筛选出的结果。如果你需要做的是在你的应用程序的多个地方，它是一个好主意，建立一个辅助类，提供了不同的选择。例如，我常用的命名空间preFIX过滤器，接口实现过滤器和过滤器继承

To look for specific types (e.g. implementing a given interface, inheriting from a common ancestor or whatever) you'll have to filter-out the results. In case you need to do that on multiple places in your application it's a good idea to build a helper class providing different options. For example, I've commonly applied namespace prefix filters, interface implementation filters, and inheritance filters.
