Newbie question: How to use C++ in .Net Framework

[Fred]

Hi, all:
I'm new to .Net, so don't laugh at my questions if they sound
silly.
Here it comes, I want to utilize classes in .Net framework
namespace, such as system.collections. Things become simple if I'm
coding in C#( just using ... ), however, I'm modifying a C++ program,
and, it's MFC supported. I think what I should do is to import
corresponding libs to introduce classes and namespaces in .Net
framework. Am I right?
That's the first question. The second is, importing libs seems
tricky, there're few examples I could follow, is it better for me to
build a COM/DLL with C# so that I could just call it in C++?
It would be more convenient if some background is supplied. My
object is to use a serializable hash class to store a large amount of
URLs. It must be serializable, so that at the first time, I could
build hash with URLs as keys, then dump the hash into a file. From
then on, when I get a new URL, first I should load the hash from the
file, next, I could check it among the URLs for existance, rebuild
hash could be avoided.
As to my situation, which hash class is suitable? I've got
system.collections.hashtable, and some
System.Security.Policy.hash, ... Thanks a lot for you help.

Can't help you on the first part, but good luck I used to do C++ and from my
understanding at least in pre 3.5 versions of the .net framework it was not
well integrated.
However sa far as the proper namespace for the hashtable you would want
the one under System.Collections. This will give you a hash table that does
not have a specified type so you will hav to cast the objects in it each time
they are accessed. If you look at System.Collections.Generic you will find
Dictionary <TKey, TValue> which allows you to specify the type for the key
and the value that the dictionary will store. If you are simply storing a
list of urls, the List<T> class may be better suited for you.
