Write a set of bytes into a 'so-called' binary file. The point is that we use BinaryWriter here and we have a byte array as input.

So... this is a simple and great 
way for validate email address using regular expressions. happy programming!
9
Copy a file to a new location, optionally marking the file as a temporary file (to be deleted on application exit).
Note there are issues for temporary files - not all the parent directories that might be created are guaranteed to be deleted - only the immediate parent directory will be deleted on exit if created. Other higher-level directories will not be deleted, even if the file is marked as temporary.

Introduction
This function is a function that returns a function. You pass it a function, and it returns a function that takes a collection as a parameter and applies your function to it. The difference between this and map is that this returns a function that you can use again which takes a collection as a parameter.
For Example
If I had a collection c, and a function p that prints its argument, I can create a visitor function using the following:
printVisitor=createVisitor(p)
Then any time I want to print a collection I just type:
printVisitor(c)
A Better Example
If you were writing an IRC server you would probably have many functions that operated on a list of users, such as ban,makeop, etc. You could create those functions in a manor similar to the following:
banUsers=createVisitor(ban)
makeOperators=createVisitor(makeop)
Then in a seperate file you could use these functions as if they were regular functions.
you would type banUsers(users) to ban, or makeOperators(users) to promote those users.
