Is it possible for StreamWriter to open different files?

I has initialized the StreamWriter instance and associated it with "MyFile.txt"

System.IO.StreamWriter sw = new StreamWriter("MyFile.txt");

So now I can write data into this file

sw.Write("Hello, world!");

Is it possible to open another file with the same StreamWriter (sw) instance some way like:

sw.Reopen("MySecondFile");

Or not/it's senseless?

Simply create a new StreamWriter instance:

StreamWriter sw = new StreamWriter("MyFile.txt");
sw.Write("Hello world!");
sw.Close();
sw = new StreamWriter("SecondFile");
sw.Write("Goodbye world!");

So, in a way it's senseless, since you can create new instances cheaply. The old instance will eventually get garbage collected automatically, so you don't have to worry about memory leaks.

Using StreamWriter you need to create a new instance to write to another file.

Looking at the documentation on StreamWriter. The only way to associate the StreamWriter with a file is in the constructor.

So, no, it's not possible to re-use an instance with a second file
