运行Visual Studio 2010实例并以编程方式附加到进程？

Question

我有一个WinForms应用程序(.net 3.5),它显示进程列表.

我希望能够附加其中一个进程.我有多个运行的Visual Studio 2010实例,我想创建一个List/Dropdown,我在其中选择其中一个实例,然后将调试器附加到它.

获取VS2010实例应该不会太难,但我不知道如何调用"附加到进程"命令.我想避免使用SendKeys-Type解决方案,所以我只是想知道是否有某种方法可以做到这一点？

编辑:澄清:我想使用特定的运行VS2010来调试外部应用程序.

一种方法是使用EnvDTE,这是Visual Studio的COM自动化接口:

http://msdn.microsoft.com/en-us/library/envdte(VS.100).aspx

您可以通过在运行对象表(ROT)中捕获来获取运行Visual Studio实例的自动化接口.一旦有了接口实例,就可以自动选择Visual Studio实例来附加到您想要的进程.

以下是如何执行此操作的基本示例.您需要向EnvDTE添加对项目的引用.该程序集位于我的机器上的以下位置:

C:\ Program Files(x86)\ Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies\EnvDTE.dll

更新以提供按进程ID获取Visual Studio实例自动化接口的示例.
