.NET Forum / .NET Framework / Interop / March 2005Finding COM Interfaces
I'm getting a COM Object, but I'm not totally sure which COM Interface(s) it implements. How can I find this out? >I'm getting a COM Object, From where? >but I'm not totally sure which COM Interface(s) it >implements. > >How can I find this out? You can use the appropriate language operator (is in C#, TypeOf .. Is in VB) to check if a certain interface is implemented.

That won't necessarily work for me, because I may or may not have com wrappers already created for the COM interface. I currently have a System.__ComObject I get the Feeling that I'll have to go through the System.Runtime.Interip.Marshal class to get my information. But I'm not totally sure how to go about it.

OK, what do you have? The IID? If so you can probably use Marshal.Queryinterface().
