what is stream.please tell me the difference between file and stream class.

Ok, FileStream class is a base class for FILEIO operations
ok, this is a pretty low level class...

For example,

Dim f as New FileStream ("C:\t.vb",FileMode.OpenOrCreate)

ok, now, this class has a write function for example,
that takes in an array of bytes, an offset and
a count.

This might be a little harder to do direct writing of strings
for example.... well anyway, it is defenitly  a usable class but
the StreamWriter class however is a helper class(an even
higher level implementation)

So you could do...

Dim WriterFriendly as new StreamWriter(f) ' f would be the earlier filestream

WriterFriendly.Write("Hello")
WriterFriendly.Close


Hope this helps!
