Without Using Redim Or fixing the size at time of declaration Can anyone halp me with the following code which fixes the size at runtime...

VB

Dim arr() As String
For i as Integer=0 to 100
     arr(i)=" "
Next i

But It shows Error at: arr(i)=" "
Is there any method to overcome it without fixing the range of string array at time of declaration ?

Solution 1

with arrays you need to define the number of elements to it before hand

i.e.

dim arr(100) as string

for i as integer = 0 to 100
  arr(i)= i.tostring
next i

With using Redim and without hardcoding the array size and compile time, your only option, using arrays, is:

Dim myArray( i ) As String

where i is a variable that is set somewhere that contains of the size of the array at runtime.

You're other, and more flexible option, would be to use a generic collection of Strings.

Dim myStrings As New List(Of String)

There's no need to define its capacity at all.
