.NET 互操作:使用 C# 查找正在运行的 COM 对象的所有实例 [英] .NET Interop: Find All instances of of a running COM object with C#

问题描述

我正在通过命令行工具自动化一些 Office 应用程序(Word 和 PowerPoint).

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

我的工具需要做的一件事是定位所有正在运行的 Word 实例.

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

我知道如何获得对其中一个实例的引用...

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);
}

我的问题

如何找到所有我正在寻找的应用程序实例，而不仅仅是其中一个.

My question

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

注意:虽然我的具体问题是关于 Office 应用程序的，但我也对更一般的答案感兴趣.

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