Converting file into Base64String and back again

by

If you want for some reason to convert your file to base-64 string. Like if you want to pass it via internet, etc… you can do this 

Byte[] bytes = File.ReadAllBytes("path");
String file = Convert.ToBase64String(bytes);

And correspondingly, read back to file:

Byte[] bytes = Convert.FromBase64String(b64Str);
File.WriteAllBytes(path, bytes);
