How to find all assemblies that reference a specific dll?

I've a directory with a large number of dlls. I need to find all those that reference a specific dll.

I'm thinking about the following solution :

1. Loop the assemblies and invoke each one with ildasm
2. Dump the manifest into a text file
3. Search the text files for the required assembly name.

Yet this solution feels immensely wrong to me. Is there a better way to achieve it?
