EXEC_ADD_IN with C#: Invalid Parameter(s)

[DanG83616]

I've created a C# add-in and am trying to call it via EXEC_ADD_IN() from a model transformation template. The add-in shows up in the Extensions context menu and I can hit the break-point on the EA_GetMenuItems(). When I initiate the transform I get an Invalid Parameter(s) message before I hit the breakpoint for the function I'm calling.

The documentation says this:
"Any function that is to be called by the EXEC_ADD_IN macro must have two parameters: an EA.Repository object, and a Variant array that contains any additional parameters from the EXEC_ADD_IN call. Return type should be Variant."

For C#, I guess that would be:

Code: [Select]

public object FindGUID(EA.Repository Repository, object[] type);I also tried replacing "EA.Repository" with "object".

The template line is this:

Code: [Select]

 $result = %EXEC_ADD_IN("Pegasus", "FindGUID", "String passed from template")%
Can anyone see my mistake?

Thanks,
Dan

Hi Dan
I have declared my C# method as

Code: [Select]

public object FindGUID(EA.Repository Repository, object args)
{
     string[] arguments = (string[])args;
}

arguments[0] will equal "String passed from template"

Hope this helps

Hi Graham,
that was the trick.  

Thanks,
