Collections

[Cheryl]

Does a VB.NET collection class exist that is:

1. Two-dimensional
2. FIFO (first in, first out)

Thank you!

Does a VB.NET collection class exist that is:

1. Two-dimensional
2. FIFO (first in, first out)

I suggest to check out the classes and namespaces in the
'System.Collections' namespace.

I've been trying this, but I haven't found what I need.

I've been trying this, but I haven't found what I need.

What about the 'Queue' class?

1. Collections are not two dimensional. You have to explain in what
respect you need it to have two dimensions to be able to help you.

2. System.Collections.Queue.

Cheryl,

Queue class

I hope this helps,

I think the Queue class is only one-dimentional

A key and and a value - both strings

Cheryl,

Can not be a problem it holds object, therefore you can make your own class.

Although a it is not a dictionary, simple because of the fact that a
dictionary is not FIFO

I hope this helps,

It looks like making my own class would be my only option.

Thank you!

Mhm... What would a two-dimensional queue look like?

 

[=?ISO-8859-1?Q?G=F6ran_Andersson?=]

You mean that you want a queue where each item has a key and a value?
Not really two dimensional, but rather a double one dimensional list?

If you use framework 2.0 you can use generics to make typed lists. I
believe that you could make a queue that holds KeyValuePair-elements:

Queue<KeyValuePair<string,string>>

Not sure what you want exactly but maybe this simplistic example will work:

Private Structure myStructure
Dim Key as string
Dim Value as string
End Structure

Use that structure to hold your key-value pairs and then a Que or Stack to
hold myStructures. Should be easy to "roll" your own FIFO using this concept.

Cheryl,
How about a one-dimensional array in a Queue?
