获取实现接口的所有类型 [英] Getting all types that implement an interface

问题描述

使用反射，我怎样才能用最少的代码和最小化迭代获得所有用 C# 3.0/.NET 3.5 实现接口的类型?

Using reflection, how can I get all types that implement an interface with C# 3.0/.NET 3.5 with the least code, and minimizing iterations?

这是我想重写的:

foreach (Type t in this.GetType().Assembly.GetTypes())
    if (t is IMyInterface)
        ; //do stuff

推荐答案

我的在 c# 3.0 中是这样的 :)

Mine would be this in c# 3.0 :)

var type = typeof(IMyInterface);
var types = AppDomain.CurrentDomain.GetAssemblies()
    .SelectMany(s => s.GetTypes())
    .Where(p => type.IsAssignableFrom(p));

基本上，最少的迭代次数总是:

Basically, the least amount of iterations will always be:

loop assemblies  
 loop types  
  see if implemented.
