问题描述

我想找到从基本/接口继承的所有类型。任何人都有一个好的方法来做到这一点?想要吗?



我知道这是一个奇怪的请求,但它是我一直在玩的无所不在的。

使用Assembly.GetTypes()获取所有类型,并使用Type.IsAssignableFrom()来检查继承。让我知道,如果你需要代码 - 以及你是否使用.NET 3.5。 (很多像这样的反射任务用LINQ to Objects更简单。)



编辑:根据请求,这里有一个例子 - 它找到 mscorlib ,它实现 IEnumerable 。注意,当基本类型是通用的时,生活有点困难...

 使用System; 
using System.Collections;
using System.Linq;
using System.Reflection;

class Test
{
static void Main()
{
装配体= typeof(string).Assembly;
Type target = typeof(IEnumerable);
var types = assembly.GetTypes()
.Where(type => target.IsAssignableFrom(type));

foreach(类型类型)
{
Console.WriteLine(type.Name);
}
}
}


I'd like to find all the types inheriting from a base/interface. Anyone have a good method to do this? Ideas?

I know this is a strange request but its something I'm playing with none-the-less.

解决方案

Use Assembly.GetTypes() to get all the types, and Type.IsAssignableFrom() to check for inheritance. Let me know if you need code - and also whether or not you're using .NET 3.5. (A lot of reflection tasks like this are simpler with LINQ to Objects.)

EDIT: As requested, here's an example - it finds everything in mscorlib which implements IEnumerable. Note that life is somewhat harder when the base type is generic...

using System;
using System.Collections;
using System.Linq;
using System.Reflection;

class Test
{
    static void Main()
    {
        Assembly assembly = typeof(string).Assembly;
        Type target = typeof(IEnumerable);        
        var types = assembly.GetTypes()
                            .Where(type => target.IsAssignableFrom(type));

        foreach (Type type in types)
        {
            Console.WriteLine(type.Name);
        }
    }
}
