How to Get the Selected Cells and Rows in the Windows Forms DataGridView Control

Here basically I am showing how to get selected cells/rows in DataGridView Control and use of IEnumerator while accessing them.

                DataGridViewSelectedRowCollection m = dataGrid_ZipList.SelectedRows;

                DataGridViewRow row;

                IEnumerator Enumerator = m.GetEnumerator();

                Enumerator.Reset();

                while (Enumerator.MoveNext())

                {

                    row = (DataGridViewRow)Enumerator.Current;

                    lstPostalCodes.Add(row.Cells["POSTAL_CODE"].Value.ToString());                   

                }
