How do I "Redim Preserve" in C#

[JCruz063]

Hi All...

I'm new to C# coming from VB.
Visual Basic has a keyword named Redim [Preserve] that allows the programmer to resize an array (making it bigger) while preserving its current values. How can this be done in C#?

Thanks

Jose

AFAIK, you wouldn't.

Instead, you would use one of the built-in collection classes (Hashtable, etc).

Thanks Chip...
I'm already using the ArrayList class. I wonder how efficient it is, though!

Why not add 100000 items to it and time how long it takes?

ArrayList 'redims' less frequently than you would in VB, if you did a redim on every add. If that was your pattern in VB, ArrayList is much more efficient.

It is right, the ArrayList is better than Redim.
One thing more is that ArrayList support multiple readers concurrently.
