dynamic array

[pelican]

i am writing a class with function to add in element to array.

eg.

public class Something
 
   private arrData(0) as string
 
   sub new()
 
   end sub
 
   public function addData(byval strData as string)
 
      redim preserve arrData(ubound(arrData)+1)
 
      arrData(ubound(arrData)) = strData
 
   end function
 
end class

The above will keep on redim the array and add 1 more space to the array.

May i know is there any other way to add an element to an array without keep on redim-ming.

May i know if i keep on using the .addData function many times to add many data, will the "redim preserve", ie keep on redim the array affect the the performance.


Is there any disadvantage to use redim preserve?

Please advise.

Thanks.
