Solution 2

AFAIK, there is no method in c# which imulate redim preserve of VB.
You can use ArrayList instead.

Why use ArrayList? Unless the OP is using an object, he is much better off using a generic list as this will not require boxing/unboxing.

Solution 1

As you have discovered, an array in C# is immutable which means that you can't extend it. You can solve your problem in one of the following ways:

1. Use a generic list which grows automatically.
2. Copy your array into a temporary array, create a new instance of the original array at a larger size and copy the values back in.

As above mentioned in my question..As per the present situation of the project I can no use Array List or generic list. as 90% code already has been developed.
If there is no other solution then I can go for no. 2. Copy Array.

Thanks!
