How Can I Generate Variables Automatically?

Hi there

I need to generate some variables , like var1, var2, var3 ....

It's determined by how many records in my database.

I want to write a for() to do this. But how?

For example

for(int i=0; i<datatable.rows.count; i++)
{
    String vari = new String;
}

This is not a right way in C#, does anyone know how to?

Thanks!!!
