What is the most suitable container just for strings holding in some array with non-predetermined upper boundary, which length is unknown on it's creation.
For simple code like:
var list = new SomeContainer(); // size is unknown
for()/foreach()/do()/while() // any loop
{
list.Add(string);
}
Is it StringCollection as optimized Collection for string, or just Collection<string> or List<string> or ArrayList ? What is the different between them?
For what you need, List<string> is probably the most versatile. StringCollection was handy in 1.1, when (without generics) you needed specific classes for typed collections. Collection<string> is handy if you want to subclass it to provide validation etc.
Either way, in 3.5, LINQ will provide lots of additional methods for them - but without LINQ, List<T> has more features (Find, Sort, etc)
A List<T> would be the most efficient.
The Collection<T> class is just a wrapper for another type of list, the parameterless constructor initialises the Collection<T> with a List<T>.
An ArrayList is essentially the same as a List<object>, so you would have to cast the items to String when reading from it.
A StringCollection is just a type safe wrapper for an ArrayList.
