Hi,
How do we increase the size of array on runtime and preserve the previous
data?
I don't want to use ArrayList because the array could be a multi-dimension
array.
Thanks,

You didn't specify what type of array but for a byte array you could use the
following method:
public byte [] ReDim(byte [] array, int newSize)
{
byte [] abytNew = new byte[newSize];
Buffer.BlockCop y(array, 0, abytNew, 0, newSize);
return abytNew;
}
Buffer.BlockCop y can handle any type inherited from Array:
byte []
int []
long []
etc...

It will be a string array.

Buffer.BlockCop y also applies to string arrays:
public string [] ReDim(string [] array, int newSize)
{
string [] astrNew = new string[newSize];
Buffer.BlockCop y(array, 0, astrNew, 0, newSize);
return astrNew;

It gives error:
An unhandled exception of type 'System.Argumen tException' occurred in
WindowsApplicat ion10.exe
Additional information: Object must be an array of primitives.
if I comment out this Buffer.BlockCop y, it will work, but can't preserve the
old value.
Thanks.

My mistake, string [] doesn't inherit from System.Array
Try:
public string [] ReDim(string [] array, int newSize)
{
string [] abytNew = new string[newSize];
for(int iCounter = 0; iCounter < array.Length; iCounter++)
abytNew[iCounter] = array[iCounter];
return abytNew;
}

I got it to work after I change to Buffer.BlockCop y code to:
System.Array.Co py(array, astrNew, array.Length);

Could you give a broader statement of your original problem? What are
you trying to do? ArrayList is quite capable of supporting
multi-dimensional arrays, but it all depends upon what you want to do
with the arrays and how you want them to work.

I have a datagrid that I use in a ASP.net web page that loads customer data

I check the .HasRows property first then if it is false I skip the data bind
like so
If OraReader.HasRows Then
grdCustomerDetails.AutoGenerateColumns = False
grdCustomerDetails.DataSource = OraReader
