.NET / C # - Reflection - System.IO.File ever used

Question

Is there a way to use reflection to completely “scan” the assembly to see if System.IO.File or System.IO.Directory is being used? These are just examples of classes. Just wondering if there is a way to do this through reflection (versus code analysis).

Update : see comments

Answer 1

As Tommy Carlier said, this is very easy to do with Cecil .

using Mono.Cecil;

// ..

var assembly = AssemblyFactory.GetAssembly ("Foo.Bar.dll");
var module = assembly.MainModule;

bool references_file = module.TypeReferences.Contains ("System.IO.File");

The fantastic NDepend tool will provide you with such dependency information.

DLL NDepend , , CQL:

SELECT TYPES WHERE IsDirectlyUsing "System.IO.File"
