Need help with .NET Reflection

S

Sanat

I was working with loading .Net Assemblies through reflection to get
the list of all the classes along with their Methods and Properties
from any given module.
I am using native .Net method Assembly.LoadFrom(assemblyPathName) to
open msvcm80.dll (Managed VC runtime library file) and I am getting an
exception thrown that states A dynamic link library (DLL)
initialization routine failed. (Exception from HRESULT: 0x8007045A)

Here is the detailed exception information:
-----------------------------------------
Error : 10/31/2007 2:49:24 PM : FileReaderFactory.ExecuteReader(D:\Test

Can anybody tell how can we load msvcm80.dll file to extract its class
and method information using .NET reflection.

Thanks!

Please try use
public static Assembly LoadFrom (
string assemblyFile,
Evidence securityEvidence
)

This too does not work. First thing is what type evidence we should
pass in it. I created an empty evidence object and passed it to
Assembly.LoadFrom() method but it still throws the Runtime Error!!
popup.
