How to Save the byte array to mp4 file in c#

Question

I Have converted the mp4 file to byte array or (stream), Now i want to convert that byte array or (stream) to Mp4 file, i have searched in web regarding this concept but my problem not yet solved please give me guidence.

This is my code i have stream and byte[], i want to convert to mp4 file NetworkStream stream = client.GetStream(); int i; i = stream.Read(bytes, 0, bytes.Length);File.WriteAllBytes(@"C:\Foo.mp4", bytes);

if it is a byte array, then surely you can use new FileStream() and write it to disk... — Callum Linington

If you "converted" an existing mp4 file to a byte array, and now want a way to write the byte array out to an mp4 file, what did this program really do? Just make a copy of an existing file? What's in the byte array? The complete mp4 file or only the digitized sound? — Lasse V. Karlsen

There is nothing about it being MP4 or anything else, if it's a byte array you can save it to the file by using File.WriteAllBytes as such

 File.WriteAllBytes(myfilepath,mybytearray);

Thanks you for your response, i have used same thing, it is creating file with only 2 kb data it is not playing. my actual file size is 290kb

Then the issue is with your data not with how you're saving it. If it saves 2kb it's because your byte array is 2kb in size. It's impossible to know where you went wrong without seeing your code

NetworkStream stream = client.GetStream(); int i; i = stream.Read(bytes, 0, bytes.Length); File.WriteAllBytes(@"C:\Foo.mp4", bytes);

Don't give us small bits, show us the whole function and not in a comment but in your question. If you want help we need some context and just those few lines don't help
