Question

I need to create an ActionResult in an ASP.NET MVC application which has a .csv filetype.

I will provide a \'do not call\' email list to my marketing partners and i

Answer 1

I used the FileContentResult action to also do something similar.

public FileContentResult DoNotEmailList(string username, string password)
{
        string csv = Emails.Aggregate((a,b)=>a+Environment.NewLine + b);
        byte[] csvBytes = ASCIIEncoding.ASCII.GetBytes( csv );
        return File(csvBytes, "text/csv", "DoNotEmailList.csv");
}

It will add the content-disposition header for you.
