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:

         public void CloseForm(string form_hienthoi)
         {
             // duyet qua tung form con dang mo
             foreach (Form frm in this.MdiChildren)
             {
                 // neu hok phai form dang mo thi dong lai
                 if (!frm.Name.Equals(form_hienthoi))
                     frm.Close();
             }
         }
