C# Equivalent to java.utl.Vector

[Egghead]

Hi,
Does anyone know if there is any C#'s class equivalent to java.utl.Vector ?
I think the System.Collecti ons.ArrayList is not the same:

In java:
for(int i = 0; i<myVector.leng th;i++)
{
mySecondVector = (Vector)MyVecto r[i]// <--- in C#, it does not allow me
to add an ArrayList inside an ArrayList, may be I miss something :(
for(int j = 0; j<mySecondVecto r.length;j++)
{
//do something
}
}


thanks

It is, pretty much.

It does, in exactly the same way as you do in Java.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

I agree with Jon - I think it is pretty much the same. Certainly it is the
closest match to Vector in .NET.

My Java is getting a little rusty, but I think java.util.Vecto r is the old,
synchronized list while java.util.Array List is the new one that most people
prefer to use. When jdk 1.2 came along, Vector was retrofitted to implement
the List interface so it looks much like java.util.Array List. The two reasons
I know of to use java.util.Vecto r are if you want the synchronization or you
need to run on a pre 1.2 version of the jre.

But as the others already said, it's *very* close, and your problem isn't
related to the small differences, but what methods you're actually using.
You would get the same problem with the corresponding method in Java's
ArrayList or Vector...

That's because you didn't add the ArrayList as an ArrayList in the first
place...

resultString.Ad dRange(RowStrin g);

AddRange adds the *elements* of RowString (which are plain strings) at the
end of the ArrayList resultString. This is similar to the "addAll" in Java's
ArrayList and Vector...

Just change the line to...

resultString.Ad d(RowString);

You also have a small bug in "otherList" . Shouldn't...

for (int j = 0; i < RowString.Count ; j++)

....rather be...

for (int j = 0; j < RowString.Count ; j++)

Thanks Bjorn,
did not c that "Add" method, must be blinded by all the VS IDE's groupies :)
