I have a hashtable (h) of class objects keyed by a string (k) - the class
(c) object stored in each hastable entry has two attributes (a1 and a2).
I want to iterate through the entries of the hashtable by ordering by one of
the attributes of the class (a1 or a2).
How can this easily be achieved ? I think I have to copy to an ArrayList
then write an IComparer - but I'm not sure if this is the best way.
Any advice appreciated.

Hello,
Is there any better collection than HashTable in terms of performance, when
the type of the key is integer?

Hi all,
I am using a hashtable for my application. Its similar to word count
application. How can I sort the hashtable w.r.t.
the VALUE and not the KEY. The sample data of the table is given below
which is sorted according the URL as in Dictionary:
www.webroot.com (11)
www.webshots.com (1)
www.weddingprints.com (4)
here, Key = URL (e.g. www.webroot.com)

I have this Hashtable of Hashtables, and I'm accessing this object from
multiple threads, now the Hashtable object is thread safe for reading,
but not for writing, so I lock the object every time I need to write to
it, but now it occurred to me that maybe I could just lock one of the
Hashtables inside without locking the entire object, but then I thought
maybe some thread could instruct the outside Hashtable to remove an
inside Hashtable...

Cannot not seem to make any sense of the order that my key/values end up in
when added to the Hashtable...ideally, I would like to be able to sort the
keys/values...but not thinking it is possible.
For those who are sure going to ask why I am asking this....I use the
Hashtable for conveniently cross-referencing pairs of information...and I am
now trying to populate a combo box based on the hashtable contents using the
key as the combo...

I am running into an issue with a HashTable where it isnt holding data in the order that I am adding it. I am pulling a SqlDataReader out of a table and looping through that to add the items to the HashTable. I have an ID field (autonumber) and a Sort Index field. I want the items to be stored in the hashtable by Sort Index. However, when I add the items into the hashtable they are getting all messed up. For example, when I have the following...
