Which method is agood practise of creating DataColumn?

Question

Hi Friend,

There are several way of  creating and addinf columns to a table:

i typically use two techniques:

1. I create a columb object using datacolumn class then i add that to a columns collection

DataColumn dcCol1 = new DataColumn("Col1", typeof(int));

dt1.Columns.Add(dcCol1);

2.  use the Add() of columns collection of the table to add a Column:

DataTable dt1 = new DataTable("Tale-1");
dt1.Columns.Add("col1", typeof(int));


which method is better in creating data columns?

thanks
