通过反射接口的实现 [英] Implementations of interface through Reflection
本文介绍了通过反射接口的实现的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我怎样才能得到一个接口的所有实现通过反射在C#?
How can I get all implementations of an interface through reflection in C#?
推荐答案
答案是这样的;它会在整个应用领域 - 即每装配目前您的应用程序加载
The answer is this; it searches through the entire application domain -- that is, every assembly currently loaded by your application.
/// <summary>
/// Returns all types in the current AppDomain implementing the interface or inheriting the type.
/// </summary>
public static IEnumerable<Type> TypesImplementingInterface(Type desiredType)
{
return AppDomain
.CurrentDomain
.GetAssemblies()
.SelectMany(assembly => assembly.GetTypes())
.Where(type => desiredType.IsAssignableFrom(type));
}
据这样使用;
var disposableTypes = TypesImplementingInterface(typeof(IDisposable));
您可能还需要此功能来找到实际的具体类型 - 即,过滤出的摘要,接口和泛型类型定义
You may also want this function to find actual concrete types -- i.e., filtering out abstracts, interfaces, and generic type definitions.
public static bool IsRealClass(Type testType)
{
return testType.IsAbstract == false
&& testType.IsGenericTypeDefinition == false
&& testType.IsInterface == false;
}
