MVC Action returning a CSV File

Question

I have an Action which is responsible for pulling some data out from the database and returning it as a CSV file.

I know I could do it by returning a massive string but I was thinking if there is a clean and efficient way that could be used to return a CSV file through an MVC controller action.

Answer 1

The FileResult is what you are looking for:

http://msdn.microsoft.com/en-us/library/system.web.mvc.fileresult.aspx

public ActionResult GetFile()
{
    var stream = new StreamReader("thefilepath.txt");
    return File(stream.ReadToEnd(), "text/plain");
}

Best regards
