Call C# from SSRS

I'm new to C#, so please excuse me if this is a stupid question.

I need to call a C# script from an SSRS report, and can't figure out how to do it.  I've built a table-valued function in C# and deployed that to SQL Server, and can now embed that function in a stored procedure, so I can now have SSRS call the stored procedure which in turn executes the C# in the function.  Is that the only way to do it?  I have some C# code in a script that runs in an integration services project that I would like to execute from SSRS.  I can move this code inside the function, I suppose, but that seems like a hack.  Is there a more natural way to do it?

Thanks for any assistance.
