What is the most efficient way to save a byte array as a file on disk in C#?

Question

Pretty simple scenario. I have a web service that receives a byte array that is to be saved as a particular file type on disk. What is the most efficient way to do this in C#?

Answer 1

Perhaps the System.IO.BinaryWriter and BinaryReader classes would help.

http://msdn.microsoft.com/en-us/library/system.io.binarywriter.aspx

"Writes primitive types in binary to a stream and supports writing strings in a specific encoding."

http://msdn.microsoft.com/en-us/library/system.io.binaryreader.aspx

"Reads primitive data types as binary values in a specific encoding."
