            DataTable dt = new DataTable();
                       DataColumn dc = null;
                      dc = dt.Columns.Add("A");
                     dc = dt.Columns.Add("B");
                       dc = dt.Columns.Add("C");
                       dc = dt.Columns.Add("D");
           
                       DataRow dr = null;
            dr = dt.NewRow();
            dr[0] = this.textBox1.Text;
            dr[1] = this.textBox2.Text;
            dr[2] = this.textBox3.Text;
