Does the 2005 release of Visual Studio provide either STL (the C++ Standard
Template Library) or an equivalent for C#? I am most interested in the 2005 C#
equivalent of std::vector. 6 2506

Look at System.Collecti ons.Generic.Lis t<T>
That's the closest equivalent, I believe.

Peter, Does the 2005 release of Visual Studio provide either STL (the C++ Standard Template Library) or an equivalent for C#? I am most interested in the 2005 C# equivalent of std::vector.
In general, there are several classes in C# that provide the functionality
of std::vector. However, which to use depends on what storage model and
behavior you want to need. If you need fast lookup of random data in the
"vector", you might want to use:
System.Collecti ons.Specialized .HybridDictiona ry
If your application needs a plain vanilla queue-like behavior, you might
start with:
System.Collecti ons.Queue
If your application needs a plain vanilla array-like behavior where you
iterate over the elements, you might use:
System.Collecti ons.ArrayList
If your application needs the list to be sorted, you might use:
System.Collecti ons.SortedList
There are other collection, link-list, etc. classes, but I am sure you get
the idea. The one you pick depends on the characteristics that are most
important to the application. Start in the System.Collecti ons namespace. I
hope that helps.

Yeah, but, they all changed with 2005 to have generics too right?

VS 2005 is .NET 2.0 so it has generics. The closest to std::vector<t>
is System.Collecti ons.Generics.Li st<T> which is contiguous storage,
random acces with an indexer ([]) and easy to add new items at the end
but not in the middle. THere are other containers in
System.Collecti ons.Generics which you might want to look at as well,
depending on your exact requirements.

The ultimate truth is that there is no ultimate truth
Peter, Yeah, but, they all changed with 2005 to have generics too right?
There is a new namespace, System.Collecti ons.Generic. The Generics flavor
of the collection classes mainly provide a higher degree of type safety.
For example, let's say we want to have a dictionary that uses an integer as
the key and a DateTime as the value. The non-Generic version might be coded
as:
System.Collecti ons.Specialized .HybridDictiona ry x = new
System.Collecti ons.Specialized .HybridDictiona ry();
x.Add(1, DateTime.Now);
x.Add("Hello", "World"); // compiles and runs without errors
The non-generic version allows the wrong type of data to be added to the
collection at run-time. Also note that there are no compile-time issues.
The generics version won't allow you to even compile your application:
System.Collecti ons.Generic.Dic tionary<int, DateTime> y = new
System.Collecti ons.Generic.Dic tionary<int, DateTime>();
y.Add(1, DateTime.Now);
y.Add("Hello", "World"); // compiler error 1) can't convert string to int
and 2) can't convert string to DateTime
So one benefit of Generics is the type safety. However, there are simple
ways to guarantee type safety and use the non-generic incantations of the
collections.

Randy

Well, type-safety *and* performance. If you create an ArrayList and
call Add ((byte)10) to it a million times, you'll use up a *lot* more
memory than using List<byte>.
