How to define ,,count,,?

What I have tried:

SqlCommand cmd = new SqlCommand();
            cmd.CommandText = "SELECT COUNT(*) FROM roba_usluge";
            Int32 count = (Int32)cmd.ExecuteScalar();

            int top = 50;
            int left = 50;
            for (int i = 0; i = count.ToString(); i++)
            {
                Button button = new Button();
                button.Left = left;
                button.Top = top;
                button.Text = (i + 1).ToString();
                this.Controls.Add(button);
                top += button.Height + 2;
            }

Solution 1

Just use:

for (int i = 0; i < count; i++)

Also see: [For loops]

And I would recommend using a using statement like this:

using (SqlConnection conn = new SqlConnection(connString))
    {
        SqlCommand cmd = new SqlCommand(sql, conn);
        ...
    }

SqlConnection con = new SqlConnection("Data Source=.\\SQLEXPRESS;Initial Catalog=bss;Integrated Security=True");
SqlCommand cmd = new SqlCommand();

cmd.CommandText = "SELECT COUNT(*) FROM roba_usluge";
con.Open();
Int32 count = (Int32)cmd.ExecuteScalar();
con.Close();

int top = 50;
int left = 50;
for (int i = 0; i < count; i++)
{
Button button = new Button();
button.Left = left;
button.Top = top;
button.Text = (i + 1).ToString();
this.Controls.Add(button);
top += button.Height + 2;
}

Where I wrong here...

SqlConnection con = new SqlConnection("Data Source=.\\SQLEXPRESS;Initial Catalog=bss;Integrated Security=True");
SqlCommand cmd = new SqlCommand();

cmd.CommandText = "SELECT COUNT(*) FROM roba_usluge";
con.Open();
Int32 count = (Int32)cmd.ExecuteScalar();
con.Close();

What is the error message ?

{"ExecuteScalar: Connection property has not been initialized."}
