从 Visual Studio 加载项访问可用类型列表？

Question

Is there a way to access the types (Classes, Interfaces, etc., and their meta data) that are available inside the loaded projects within a solution in Visual Studio?

To be more specific, I'm attempting to develop a simple Visual Studio Add In to provide "Go To Implementation" functionality:

https://bitbucket.org/jbubriski/go-to-implementation/

I realize that this exists in other productivity Add Ins/Extensions, but I'm making a bare bones one so我 don't have to deal with slow downs, hangs, and crashes from other added "features".

If you look at the source, I'm able to get the currently selected text using a very basic and fragile method. Given the selection, I basically assume that it is an interface, strip off the 'I', and do a Solution-wide search for ProjectItems where the file name ends in "\TypeName.cs “。

Is there some internal list of types that Visual Studio maintains for intellisense that I have access to? It would be nice to say:

var vsType = VS.GetLocalType("TypeName")

Then access

vsType.FileName

One step further would be

foreach(var vsType in VS.GetlocalTypes())
{
    if(vsType.Implements.Contains("IInterfaceName"))
    {
        // Found something that implements my interface!
    }
}

Any ideas?

不确定本机 VS 插件实现，但如果您使用 DevExpress.CodeRush，转到定义功能应该基于源文件中的当前位置，并执行类似以下操作来检索对声明类型的引用：
((TypeReferenceExpression)CodeRush.Source.Active).GetDeclaringType()

PS I understand that I didn't answer on yor question, but hope this will give you a direction to search a solution
