C＃中的byte [] encodeBase64（byte [] binaryData）等效

Question

In Java, Apache provides a encoding library namely apache-commons and there is a method that's signiture is

byte[] encodeBase64(byte[] binaryData)

In C#, we try to do the same thing. however, we couldn't find any library or method like this. How we can encode our byte array to Base64 byte array?

Answer 1

You can leverage the Convert.ToBase64String method. This will however not return a byte[] but a string type. To get it in bytes, you will have to perform a text encoding.

string base64 = Convert.ToBase64String(binaryData);
byte[] base64bytes = System.Text.Encoding.ASCII.GetBytes(base64);
