NP120 understanding instance

Hi Guys

NP120 understanding instance

FileStream fs = new FileStream ("aFile.txt", FileMode.Create, FileAccess.ReadWrite,FileShare.None);

StreamWriter sw = new StreamWriter(fs);

I have had a problem in understanding the above one. I wish to know whether it is correct to say instance of a StreamWriter which is sw is equal to instance of a FileStream which is fs. That means sw = fs.

Please help me.

Thank you

No, it's not correct to say that an instance of a StreamWriter is equal to an instance of a FileStream, because they are different (and unrelated) classes.

When you execute this line:

StreamWriter sw = new StreamWriter(fs);

you are constructing an instance of StreamWriter and associating it with a FileStream object to write to. In other words, StreamWriter writes to streams, it is not a stream itself.
