.NET互操作：找到一个正在运行的COM对象与C＃的所有实例 [英] .NET Interop: Find All instances of of a running COM object with C#

问题描述

我通过自动化命令行工具，一些Office应用程序（Word和PowerPoint）。

I am automating some Office application (Word and PowerPoint) via command-line tool.

我想我的工具需要做的就是找​​到Word的所有正在运行的实例。

One thing my tool needs to do is locate all the running instances of Word.

我知道如何让一个参考实例之一...

I know how to get a reference to one of the instances...

Object running_obj = null;
{
    running_obj = System.Runtime.InteropServices.Marshal.GetActiveObject(progid);
}
catch (System.Exception)
{
    //failed to find the object;
}
if (running_obj!=null)
{
   var running_obj_type = System.Type.GetTypeFromProgID(progid);
   Microsoft.Office.Interop.Word.Application running_obj_wrapper;
   running_obj_wrapper = 
            (Microsoft.Office.Interop.Word.Application)
            System.Runtime.InteropServices.Marshal.CreateWrapperOfType(
                  running_obj, running_obj_type);
}

我的提问

如何找到的所有的应用程序的情况下，我找的，不只是他们中的一个。

My question

How to find all the instances of the application I am looking for, not just one of them.

请注意：虽然我的具体问题是关于Office应用程序，上午上午的也的兴趣答案，都比较一般

NOTE: Although my specifics question is about Office applications, am am also interested in answers that are more general.
