How to invoke a method in a dll with Invenotr API?

[bim01]

I have encountered a problem during coding with my colleagues, is anyone can help, Here is the problem:

• in “project2”, I defined a class named “CsA”，and a method called “FuncA()”, compiled the “project2”to “project2.dll”.
• in “project1”,I add the reference of “project2.dll”, then in the Activate(……) function, I tried to instantiate an object of “CsA“, but faild here (see the picture).
• And I tried another way: I put “CsA”in “project1”then compiled it, the program runs well.
• So how to invoke a method in a dll coded by someone else under the circumstances of collaborating with colleagues? Or it is impossible to do so in Inventor?

Circumstances: Inventor professional 2018, windows 7

This seems like more of a C# question than an Inventor API question. Try looking in stack overflow, you might have better luck. This may be what you need:

Hi,

Is the dll file copied with the build of the project to the directories needed?

Yes, local copy set true

I can run the program sucessfully in pure C# or in Revit environment, but faild in Inventor environment, so I think maybe Inventor has something sepcial... Thanks!

You could take a look at the referenced inventor version in either the dll and in the project, are they the same?
