Why Console.WriteLine in ASP.NET application not writing to file?

Question

I was doing some trials on the basis of the following Q&A: Where does Console.WriteLine go in ASP.NET?.

The code I tried goes like below:

    var fs = new System.IO.FileStream(@"D:\log.txt", System.IO.FileMode.Append);
    var tr = new System.IO.StreamWriter(fs);
    Console.SetOut(tr);
    Console.WriteLine("My Default Debugging");
    fs.Close();

Here I am setting the FileStream fs to StreamWriter tr and in turn setting it as Console.Out by calling Console.SetOut(). So, by that I am expecting it to write to the file by Console.WriteLine(). Though my file gets created, it is empty.

What can be the thing I am missing here?

is the same code working fine in a console application ? and i'll also close write object — donstack, Sep 19 '13 at 10:35
I tried it in a web application. it works if i add `tr.close` before `fs.close` as sekky told. — RinoTom, Sep 19 '13 at 10:55

try tr.WriteLine("string"); instead.

It is a good alternative, but my intention was here to make use of `Console.WriteLine` as mentioned in the Q&A http://stackoverflow.com/questions/137660/where-does-console-writeline-go-in-asp-net – RinoTom Sep 19 '13 at 11:30

Becuase Console.WriteLine() doesn't do that?

Writes the specified data, followed by the current line terminator, to the standard output stream.

Console.WriteLine() does that and FileStream is a standard output stream. – RinoTom Sep 19 '13 at 11:29

var fs = new System.IO.FileStream(@"D:\log.txt", System.IO.FileMode.Append);
var tr = new System.IO.StreamWriter(fs);
Console.SetOut(tr);
Console.WriteLine("My Default Debugging");
tr.Close();
fs.Close();

Maybe it's because you didn't close the StreamWriter before you closed the FileStream?
