You can define array of table like this

C#

DataTable[] tableArray = new DataTable[10]; // define DataTable array of Size 10

for(int i=0;i<10;i++)
 tableArray[i] = new DataTable();//create new data Table

jibesh you are absolutely right but if you use dataset rather that array I think it would me better.

Yes. That's another way of doing it. If I want array of table I usually do not prefer DataSet to avoid the other overheads, unless it requires operations supported by dataset

Exactly :)

Hi
you can use from following code for create dynamic size of Data Table.
in this example you can get size of data table from user by console and create your DataTable and if user enter zero this while loop will be finished.

C#

DataTable[] table;
int n;

while (true)
{
    Console.Write("Please enter size of Data Table: ");
    n = int.Parse(Console.ReadLine());

    if (n == 0)
        break;

    table = new DataTable[n];
}
