How to convert string to base64 byte array, would this be valid?


c# .net string bytearray base64

You can use:

From byte[] to string:

byte[] array = somebytearray;

string result = Convert.ToBase64String(array);

From string to byte[]:

array = Convert.FromBase64String(result);

c# .net string bytearray base64

Looks okay, although the approach is strange. But use Encoding.ASCII.GetBytes() to convert the base64 string to byte[]. Base64 encoding only contains ASCII characters. Using Unicode gets you an extra 0 byte for each character.

c# .net string bytearray base64

Representing a string as a blob represented as a string is odd... any reason you can't just use the string directly?

The string is always unicode; it is the encoded bytes that change. Since base-64 is always <128, using unicode in the last part seems overkill (unless that is what the wire-format demands). Personally, I'd use UTF8 or ASCII for the last GetBytes so that each base-64 character only takes one byte.
