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

I tried it in a web application. it works if i add tr.close before fs.close as sekky told. — RinoTom

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 stackoverflow.com/questions/137660/…

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?

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.
