It's not clear what you mean by "in base64" in this case. Please give more details.

When you've got a byte array, you'd usually just call:

File.WriteAllBytes(filename, data);

Now if you've got base64 encoded data, that's usually in the form of a string - so you'd use

byte[] binaryData = Convert.FromBase64String(base64String);
File.WriteAllBytes(filename, binaryData);
