问题描述

有时候我想找出实现特定接口的所有标准的.NET类型的列表。通常它是出于好奇,有时也有一些实际的目的,(但是这不是问题的关键)。

我试图让这一点在MSDN的,但类型的页面只包含指向儿童的类型,而不是类型实现接口。

你知道有窍门如何做到这一点(或者一个工具,可以帮助)?

我写这篇code(的ICollection 的类型正在调查中):

  VAR的结果=
            从组装AppDomain.CurrentDomain.GetAssemblies()了ToList()
            在assembly.GetTypes从类型()
            其中,typeof运算(ICollection的).IsAssignableFrom(类型)
            选择类型;

        的foreach(在结果VAR型)
        {
            Console.Out.WriteLine(type.FullName);
        }
 

但是,这有一定的局限性:

  1. 只搜索当前加载的程序集。
  2. 在我无法想出一个办法做到这一点的通用接口(的ICollection<> 是行不通的)。
  3. 这将是很好,如果它提供的链接,MSDN(但我客串,可能是固定的)。

感谢您的帮助!

解决方案
  

它只搜索当前加载   组件。

总是有添加引用对话框,但你可能想看看这样一个问题:列出所有可用的.NET程序集的。

  

我无法想出一个办法做到这一点   对于通用接口(ICollection的<>   是行不通的)

试试这个查询,而不是:

 从组件AppDomain.CurrentDomain.GetAssemblies()
在assembly.GetTypes从类型()
其中,type.GetInterfaces()
          。任何(I => i.IsGenericType
                 &功放;&安培; i.GetGenericTypeDefinition()== typeof运算(ICollection的<>))
选择类型;
 

  

这将是很好,如果它提供的链接   MSDN的。

.net反射支持搜索类型的实施下,接口类型(选择派生类型 ),以及在搜索类型为MSDN文档(在类型单击鼠标右键,选择搜索MSDN)。

如果你不喜欢这个选项,你当然可以尝试编写的软件运行在MSDN上的Web搜索的类型的完全限定域名的东西。我不知道是否有任何元数据围绕映射一个类型的MSDN页面或实现这个目的的清洁方式。

Sometimes I want to find out a list of all standard .NET types that implement a specific interface. Usually it is out of curiosity, sometimes there is also some practical purpose (but that's not the point).

I tried to get this out of MSDN, but type's page only contains links children of types, not types implementing interface.

Do you know any trick how to do this (or a tool that would help)?

I wrote this code (ICollection is the type being investigated):

        var result =
            from assembly in AppDomain.CurrentDomain.GetAssemblies().ToList()
            from type in assembly.GetTypes()
            where typeof(ICollection).IsAssignableFrom(type)
            select type;

        foreach (var type in result)
        {
            Console.Out.WriteLine(type.FullName);
        }

But this has some limitations:

  1. It only searches currently loaded assemblies.
  2. I couldn't figure out a way to do this for generic interfaces (ICollection<> wouldn't work).
  3. It would be nice if it provided links to MSDN (but I gues that could be fixed).

Thanks for help!

解决方案

It only searches currently loaded assemblies.

There's always the "Add Reference" dialog, but you might want to look at the question: List all available .NET assemblies.

I couldn't figure out a way to do this for generic interfaces (ICollection<> wouldn't work)

Try this query instead:

from assembly in AppDomain.CurrentDomain.GetAssemblies()
from type in assembly.GetTypes()
where type.GetInterfaces()
          .Any(i => i.IsGenericType
                 && i.GetGenericTypeDefinition() == typeof(ICollection<>))
select type;

It would be nice if it provided links to MSDN.

.NET Reflector supports searching for types implementing an interface (choose "Derived Types" under a type) as well as searching MSDN for documentation on a type (right-click on a type and choose "Search MSDN").

If you don't like that option, you could of course try to write something that runs a web-search on MSDN with the type's full-qualified name. I'm unaware if there's any metadata around that maps a type to its MSDN page or a clean way of accomplishing that.
