.NET - 获得一个通用接口的所有实现？ [英] .NET - Getting all implementations of a generic interface?

问题描述

在<一的回答href="http://stackoverflow.com/questions/80247/implementations-of-interface-through-reflection">Implementations通过反射界面的说明如何获取一个接口的所有实现。然而，鉴于通用接口， IInterface＆LT; T＆GT; ，下面不工作：

An answer on " Implementations of interface through Reflection " shows how to get all implementations of an interface. However, given a generic interface, IInterface<T>, the following doesn't work:

var types = TypesImplementingInterface(typeof(IInterface<>))

谁能解释我如何可以修改的方法？

Can anyone explain how I can modify that method?

推荐答案

您可以使用这样的：

public static bool DoesTypeSupportInterface(Type type,Type inter)
{
    if(inter.IsAssignableFrom(type))
        return true;
    if(type.GetInterfaces().Any(i=>i. IsGenericType && i.GetGenericTypeDefinition()==inter))
        return true;
    return false;
}

public static IEnumerable<Type> TypesImplementingInterface(Type desiredType)
{
    return AppDomain
        .CurrentDomain
        .GetAssemblies()
        .SelectMany(assembly => assembly.GetTypes())
        .Where(type => DoesTypeSupportInterface(type,desiredType));

}

它可以尽管抛出一个TypeLoader异常，但是这是一个问题已经美元的原来的$ C $中c p $ psent。例如，在linqpad这是行不通的，因为无法加载一些库。

It can throw a TypeLoader exception though but that's a problem already present in the original code. For example in linqpad it doesn't work because some libraries can't be loaded.
