Library help: a set class needed

Library help: a set class needed

• KP99

  i don't think microsoft added this support for .NET 2.0 but for 1.1 we are using Iesi.Collections from this project (http://www.codeproject.com/csharp/sets.asp).
  
  you might also want to checkout the PowerCollections

  "The C# and Java Hashset share just the name."

  C# doesn't have a Hashset (or any set implementation), it has a Hashtable. One can easily implement their own set class, however, by using a Hashtable internally to track what items have been added to the set and prevent duplicates from being added a second time. This how the Hashset class in java works. The name isn't misleading. Its says exactly what it is. Its a set that is implemented internally using a hashtable or similar hashing scheme. As the other poster suggested, the Power Collections being developed for .NET 2.0 by 3rd parties may have what you're looking for.

  No, it's still not what I'm looking for.
  
  The Java Hashset does not collect it items through a key/value pair, just values that are unique to each other. It bases its unique list by using a hash in some way (I'm not shure about exactly how), but probably not the most efficient implementation.
  
  The meaning behind a Set is described here in the first paragraph of the Java API:
  http://java.sun.com/j2se/1.5.0/docs/api/java/util/Set.html
  
  
  What about something similar to :
  http://java.sun.com/j2se/1.5.0/docs/api/java/util/TreeSet.html ( )
  
  
  The C# and Java Hashset share just the name. (However I think it's a misleading name in the Java API). I aplogize for using hashset as an example, as it might have been confusing.
