How to retrieve only the structure of a DataTable i.e. all the columns?

Answer:

DataTable Clone() method is used for retrieving all the columns a DataTable have.

It only retrieve structure not rows.

For Example:-

DataTable new_dt = new DataTable();

new_dt = dt_employee.Clone();

So,whatever dt_employee Datatable contains columns will be assigned to new_dt DataTable.

Here dt_employee is another DataTable.
