Hi,
I'm looking for a generic version of a map container that acts similar like
the multimap known from C++ / STL .
<code>
Dictionary<string, myobjectmap = new Dictionary<string, myobject>();
map.Add("CATEGORY1", new myobject());
map.Add("CATEGORY1", new myobject(); // <-- this is not possible here,
// because the Net 2.0 Dictionary
only supports
// unique keys.
</code>
It should support multiple objects per key.
Does anybody have a good solution / code for this ? And by the way, I heard
of STLNET ? But as I understood, this is only for C++ available ? Or does
this work under C# ( I found no documentation abaout this so far).
Thanks,
Florian 6 6100
I think it's easy to make a custom collection like this yourself based
on the existing ones, or you can use something like this:
Dictionary<string, List<myobject>map = new Dictionary<string,
List<myobject>>();
map.Add("CATEGORY1", new List<myobject>());
map["CATEGORY1"].Add(new myobject());
map["CATEGORY1"].Add(new myobject());

Hi Wiebe,
ouch, looks pretty obvious. Ok, it's worth a try. BTW, anything heard of
this STLNET stuff. Is my intepretation correct ? If it's .Net based, it
should work fine with C# but I've not idea where to look for...

Hi,
I didn't look at the STLNET yet, sorry. I didn't however find much that
isn't done easily with the classes already in C#.
Also take a look at the System.Collections.ObjectModel.KeyedCollection
class (my favorite), because it's like a HashTable but includes an
indexer (Int), and you can add items without having to specify the key.
I really have no idea why they put it in the
System.Collections.ObjectModel namespace.
Regards, Wiebe

It just works with CLI/C++.
