How do I best generate a CSV (comma-delimited text file) for download with ASP.NET?

Question

This is what I\'ve got. It works. But, is there a simpler or better way?

One an ASPX page, I\'ve got the download link...

Answer 1

I pass all my CSV data through a function like this:

Function PrepForCSV(ByVal value As String) As String
    return String.Format("""{0}""", Value.Replace("""", """"""))
End Function

Also, if you're not serving up html you probably want an http handler (.ashx file) rather than a full web page. If you create a new handler in Visual Studio, odds are you could just copy past your existing code into the main method and it will just work, with a small performance boost for your efforts.
