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 btninsert_Click(object sender, EventArgs e)
         {
             try
             {
                 if (db.CRUDPhieuMuon('t', cbxMaSach.Text, cbxMaThe.Text, txtMuon.Text, txtTra.Text) == 1)
                 {
                     db.SubmitChanges();
                     MessageBox.Show("Mượn Thành Công", "Thông Báo", MessageBoxButtons.OK, MessageBoxIcon.Information);

                 }
                 else
                     MessageBox.Show("Mượn Thất Bại", "Thông Báo", MessageBoxButtons.OK, MessageBoxIcon.Warning);
             }
             catch (Exception ex)
             {
                 MessageBox.Show(ex.Message, "Quản Lý Thư Viện");
             }
             finally
             {
                 LoadGridView();
             }
         }
