What is different between FileStream and StreamWriter in dotnet?
FileStream is a
Stream. Like all Streams it only deals with
StreamWriter is a
TextWriter, a Stream-decorator. A TextWriter converts or encodes Text data like string or char to
byte and then writes it to the linked
What context are you supposed to use it? What is their advantage and disadvantage?
You use a bare FileStream when you have
byte data. You add a
StreamWriter when you want to write text.
Is it possible to combine these two into one?
Yes. You always need a Stream to create a StreamWriter.
System.IO.File.CreateText("path") will create them in combination and then you only have to Dispose() the outer writer.
