How to write to a StreamWriter without flush or close

Question

I am trying to redirect the standard output to a file for logging purpose.

Dim tmp As TextWriter = Console.Out  
Dim sw As StreamWriter = File.AppendText("log.txt"))
Console.SetOut(sw)
Console.Write("Test")

but it looks like nothing get written until I call Flush() or Close() on the StreamWriter. Since the stream is going to stay open for a long time (Until the application closes), I would like the buffer to write directly to the file, otherwise it might become really big. How can I do that ?

Use a [Using Statement](https://msdn.microsoft.com/en-us/library/htd05whh.aspx) — IronAces, Apr 05 '17 at 15:53
As for now I create the StreamWriter in a constructor and I close it in its destructor so I can't wrap it in a Using block. Is there a better way ? — TSpark, Apr 05 '17 at 16:00

You can set your StreamWriter.AutoFlush property to true:

AutoFlush to true means that data will be flushed from the buffer to the stream after each write operation, but the encoder state will not be flushed
