CREATING CSV FILE IN ASP.NET



        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();
