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 frmKetQua(string strten, string strma, string strdiem, string strsocaudung)
         {
             string strCon = "server=.\\SQLEXPRESS;database=QL_Thitracnghiem;integrated security=true";
             ObjCon = new SqlConnection(strCon);
             ObjCon.Open();
             InitializeComponent();


             getvalueformdienten = strten;//ten
             getvalueformdienma = strma;//ma thi sinh
             getvaluediem = strdiem;//diem
             getvaluesocaudung = strsocaudung;//so cau dung
             socausai = 50 - int.Parse(strsocaudung);//so cau sai
             lbsocausai.Text = socausai.ToString();
         }
