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 loadCmb()
{
SqlConnection con = dal.GetConnect();
con.Open();
SqlCommand cm = new SqlCommand("Select *from Lop", con);
SqlDataAdapter da = new SqlDataAdapter(cm);
DataTable dt = new DataTable();
da.Fill(dt);
this.cmbMaLop.DisplayMember = "MaLop";
this.cmbMaLop.ValueMember = "MaLop";
this.cmbMaLop.DataSource = dt;
}
{
SqlConnection con = dal.GetConnect();
con.Open();
SqlCommand cm = new SqlCommand("Select *from Lop", con);
SqlDataAdapter da = new SqlDataAdapter(cm);
DataTable dt = new DataTable();
da.Fill(dt);
this.cmbMaLop.DisplayMember = "MaLop";
this.cmbMaLop.ValueMember = "MaLop";
this.cmbMaLop.DataSource = dt;
}
