C# WPF Convert a byte array into video file?

Question

I have a MPEG file which I have converted into a byte array. The intention is for a client to retrieve this byte array then save the MPEG file locally where it will be used in an WPF application.

I can convert the MPEG file to a byte array, but I don't know how to convert the byte array back to MPEG or save the byte array as an MPEG file.

How do I do this?

BTW any infomation about converting a byte array to any video format which WPF supports would be helpful.

So, "I can convert the MPEG file to a byte array" - maybe show us how you do that. — Henk Holterman

Thats a very good point! I didn't test my code which converts from mpeg to byte array. And it isnt working! So how do I read the mpeg file into my own byte array within my function? Is this even possible? — endorphin

The code which I have to convert any file to byte array isnt working when I give the function the path for the mpeg file. I am using the FileToByteArray function found here - digitalcoding.com/Code-Snippets/C-Sharp/… . I receive an IOException when I try to use FileStream to open the mpeg file for reading. — endorphin

"Configuration information could not be read from the domain controller, either because the machine is unavailable, or access has been denied.\r\n" --- Its my local machine, so should definately be available -- on the other hand, I have no idea why access to the file would be denied?! — endorphin

You can call File.WriteAllBytes to write a byte array to a file.

If the byte array contains a different format (eg, DivX), you'll need to transcode the file to MPEG, perhaps using ffmpeg.

What about System.IO.File.WriteAllBytes(myFileName, mpegDataByteArray)?
