We have no idea what file do you mean. It's likely that you don't have to extract a key by yourself and can use the file itself. Without knowing what is it, it makes no sense.

What kind of file? How it's named? Is it XML? something else? *.snk, *.pfx, anything else? Normally, you can use the file itself to use the key it stores...
