Only load managed-load DLLs into the directory

Question

I need to load all assemblies from a DLL into a directory.

My base code is:

var assemblies = from filename in Directory.GetFiles(HttpRuntime.BinDirectory, "*.dll")
                 select Assembly.LoadFrom(filename);

However, if there are unmanaged DLLs in this directory, then Assembly.LoadFrom fails. Is there a way to load only managed DLLs? Capturing a boot exception is an option, but I would like to know if there is a better way.

My code runs on ASP.NET when the application starts. Therefore, I also agree with the specific ASP.NET solution.

Answer 4

Call GetAssemblyName(), and if it throws a BadImageFormatException, then this is not an assembly.
