Creating CSV file

SqlConnection conn = new SqlConnection();
        SqlCommand com = new SqlCommand();
        conn.ConnectionString = "TYPE CONNECTION STRING HERE";
        string query_str = "WRITE QUERY HERE";
        com.CommandText = query_str;
        com.CommandType = CommandType.Text;
        com.Connection = conn;

        SqlDataAdapter da = new SqlDataAdapter();
        da.SelectCommand = com;
        DataSet ds = new DataSet();
        da.Fill(ds);

        DataTable dt = ds.Tables[0];

        HttpContext context = HttpContext.Current;

        context.Response.Clear();
        context.Response.ContentType = "text/csv";
        context.Response.AddHeader("Content-Disposition","attachment; Filename = FILE.csv");

        for (int i = 0; i < dt.Columns.Count - 1 ; i++)
        {
            if (i > 0) context.Response.Write(",");

            context.Response.Write(dt.Columns[i].ColumnName);
        }
        context.Response.Write(Environment.NewLine);

        foreach (DataRow dr in dt.Rows)
        {
            for (int i = 0; i < dt.Columns.Count - 1; i++)
            {
                if (i > 0) context.Response.Write(",");

                context.Response.Write(dr.ItemArray[i].ToString());
            }
            context.Response.Write(Environment.NewLine);
        }

        context.Response.End();
