Does File() In asp.net mvc close the stream?

Question

Hi

I am wondering if you do something like

public FileResult result()
{
   Stream stream = new Stream();
   return File(stream,"text/html","bob.html");
}

if File() would close the stream for you? Since I tried to put the "stream" in a using statement but it always gave me a error saying the stream was closed.

public FileResult result()
{
    using(Stream stream = new Stream())
    {
       return File(stream,"text/html","bob.html");
    }
}

Answer 1

This might help.

Using Statement

Answer 2

If you are using the File object to send the resulting file for download as bob.html then yes.

I believe that all standard Streams (OutputStream, FileStream, CryptoStream) will attempt to flush when closed or disposed.

There are a number of classes within the MVC framework that implement the base FileResult class.

System.Web.Mvc.FileResult
System.Web.Mvc.FileContentResult
System.Web.Mvc.FilePathResult
System.Web.Mvc.FileStreamResult
