如何获取 COM 对象的类型

How to get type of COM object(如何获取 COM 对象的类型)
本文介绍了如何获取 COM 对象的类型的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我在 Visual Studio 中引用了一个 COM 库,因此它已自动为我创建了相应的 Interop 程序集.我想对这些 com 对象执行 GetType(),但它们总是返回 System.__ComObject.不过,查询它们的接口是可行的:

bool isOfType = someComeObject is ISomeComObject;//这有效

但我真正想要的是返回 com 对象的实际类型:

Type type = someComeObject.GetType();//返回 System.__ComObject :-(

有人知道我想做的事怎么做吗?

解决方案

添加对 Microsoft.VisualBasic.dll 的引用 然后:

Microsoft.VisualBasic.Information.TypeName(someCOMObject)

MSDN 参考这里.p>

I am referencing a COM library in Visual Studio, so it has automatically created the corresponding Interop assembly for me. I would like to do a GetType() on these com objects, but they always return System.__ComObject. Querying them for an interface works though:

bool isOfType = someComeObject is ISomeComObject; //this works

But what I really want is this to return the actual type of the com object:

Type type = someComeObject.GetType(); //returns System.__ComObject :-(

Does anyone know how to do what I want to do?

解决方案

Add reference to Microsoft.VisualBasic.dll and then:

Microsoft.VisualBasic.Information.TypeName(someCOMObject)

MSDN reference here.
