Copying and Pasting cs Code

In cs, like in almost any computer programming language, reading data from a file can be tricky. You add extra lines of code to tell the computer what to do. Sometimes you can copy and paste these lines from other peoples’ code.

For example, you can follow the pattern in this listing:

         private void btndel_Click(object sender, EventArgs e)
         {
             try
             {
                 if (MessageBox.Show("Bạn Có Muốn Xóa Không", "Thông Báo", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
                 {

                     if (db.CRUDThe('x', txtMaThe.Text, String.Empty, String.Empty, String.Empty) == 1)
                     {

                         db.SubmitChanges();
                         MessageBox.Show("Xóa Thành Công", "Thông Báo", MessageBoxButtons.OK, MessageBoxIcon.Information);
                     }
                     else
                     {
                         MessageBox.Show("Xóa Thất Bại", "Thông Báo", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                     }
                 }
             }
             catch (Exception ex)
             {
                 MessageBox.Show(ex.Message, "Quản Lý Thư Viện");
             }
             finally
             {
                 tbTHE.LoadGridView(dataGridViewX1);

             }
         }
