C# counterpart to VB.NET Redim

[Guest]

Hi
What is the best way to enlarge an C# array which already have values?
In VB.NET I would do
ReDim Preserve A(10)

You need to reallocate and copy yourself. To can use the array's Copy(To)
method for this purpose.

If you don't want to do this, just use an ArrayList instead of an array and
just Add() elements all you want and let the collection take care of things
for you.

Additionally, in .NET 2.0, you can just use the Generic type List<T>
which will do this as well and give you type safety.

First of all, a .NET collection such as ArrayList might be preferable.
However, if you want to resize an array, then the following is what you need:
(assuming an array of type "SomeType")

SomeType[] temp = new SomeType[11];
if (A != null)
Array.Copy(A, temp, Math.Min(A.Length, temp.Length));
A = temp;

List<T> is dynamic, so you don't even need to redim.
