Storing Objects

[Hunter]

Hi,

In one of my forms I need hold an array of objects (same class) that is
dynamic at runtime. Instead of using an array I am looking at ArrayList or
Hashtable. Any suggestions?

Re: Storing Objects

If you're using .Net 2.0, try a generic list, such as List<Tor
Dictionary<T>.

Either way, don't expose the collection outside the class (if you're
buidling something as part of a library).

If you are using .NET 2.0, go for a generic collection such as List<T>.
You pass your class name to it when creating the collection, so it's
totally typesafe. You also skip the effort involved in casting back to
the right class when getting data out.

List<MyClasslis t = new List<MyClass>() ;

If you need to store the objects by key and then get an object back
given its key, then use a Hashtable.

If you just want to get at the objects by index, or just need a list
you can iterate over, use an ArrayList or, better yet, List<Tin .NET
2.0.

If you need both a key lookup and to maintain the objects in a
particular order, use a SortedList.
