如何在 EnvDTE 中仅获取当前项目中定义的类？
我有一个 Vs2010 包，当前遵循
EnvDTE=>Solution=>Projects=>CodeModel=>CodeElements
递归执行以下操作并查找类
var q = elements.Cast<CodeElement>()
.Where(x => x is CodeClass || x is CodeNamespace)
.Where(x => x.Name.StartsWith("System") == false)
.Where(x=>x.Name.StartsWith("Infragistics")==false)
.Where(x=>x.Name.StartsWith("Microsoft")==false)
.Where(x => x.Name.StartsWith("ICSharpCode")==false);
它运行速度相当慢，有没有办法将此查询/搜索限制为仅在当前项目中定义的类/类型？
据我了解，FileCodeModel既无用也不合适，因为这需要打开每个项目项。

.Where(x=>x.Name.StartsWith("Microsoft")==false)
.Where(x => x.Name.StartsWith("ICSharpCode")==false);
It runs fairly slowly, is there a way to restrict this query/search to only classes/types defined within the current project?
As I understand it FileCodeModel is neither useful nor appropriate since that would require opening every project Item.

我用于导航 Project.CodeModel 或 ProjectItem.FileCodeModel 的代码元素的方法在文章中进行了描述：
HOWTO：从 Visual Studio .NET 宏或加载项导航文件的代码元素

如果性能是一个问题，请尝试避免 LINQ 层是否可以提高性能。除此之外，没有什么可做的，因为 EnvDTE 返回的 CodeElements 集合返回所有代码元素，并且在您过滤之后。

If performance is an issue, try if avoiding the LINQ layer enhances the performance. Other than that there is no much to do since the CodeElements collections returned by EnvDTE return all the code elements and it is afterwards when you filter.
老问题，但我会将其发布以供将来参考。
当元素来自引用的程序集时，CodeElement 类上有一个 InfoLocation 属性，该属性等于 vsCMInfoLocation.vsCMInfoLocationExternal。

Old question, but I will post this for future reference.
There is a InfoLocation property on the CodeElement class that is equal to vsCMInfoLocation.vsCMInfoLocationExternal when an element is coming from a referenced assembly.
