There is no encoding for WriteAllBytes. Encoding relates to how strings are turned into bytes if you already have a byte array then the encoding has already been applied elsewhere.

If you look at the definition for File.WriteAllBytes http://msdn.microsoft.com/en-us/library/system.io.file.writeallbytes.aspx[^] you will see that it has only the single signature: it takes an array of bytes as a parameter and outputs it to a new file.

Since an array of bytes is defined as a sequence of 8 bit unsigned binary data http://msdn.microsoft.com/en-us/library/e2ayt412(VS.71)[^] it has no encoding, nor does it need one.

Any encoding change is performed when you convert a string to an array of bytes.
