Hello,

I'm trying to export data to a csv file, as there are chinese characters in the data i had to use unicode.. but after adding the preamble for unicode, the commas are not recognized as delimiters and all data are now written to the first column. I'm not sure what is wrong. Below is my code which i wrote in a .ashx file.

    DataView priceQuery = (DataView)context.Session["priceQuery"];
    String fundName = priceQuery.Table.Rows[0][0].ToString().Trim().Replace(' ', '_');

    context.Response.Clear();
    context.Response.ClearContent();
    context.Response.ClearHeaders();

    context.Response.ContentType = "text/csv";
    context.Response.ContentEncoding = System.Text.Encoding.Unicode;        
    context.Response.AddHeader("Content-Disposition", "attachment; filename=" + fundName + ".csv");
    context.Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());                

    String output = fundName + "\n";        
    output += "Price, Date" + "\n";

    foreach (DataRow row in priceQuery.Table.Rows)
    {
        string price = row[2].ToString();
        string date = ((DateTime)row[1]).ToString("dd-MMM-yy");

        output += price + "," + date + "\n";
    }

    context.Response.Write(output);
