Hope the code is in some function. Because the VS pointed to adding "public" directive of this function.
I want to let you know that the MS Automation works very slow, and required excel installed on the server. As an alternative you can use some free 3rd party's component.
For example, this <<snip>>

Have you actually got the interop for excel. I did this a while ago for word and access and had to download and install the interop assemblies from MS website to the GAC (Global Assembly Cache).
