WebJan 16, 2014 · BitConverter seems fairy efficient, but still about 3x to slower than ToBase64String. Furthermore, BitConverter.ToString () by itself has dashes, which have to then be removed. Once you add the Replace (), which is heavy, it drops significantly to about 8x slower. So clearly I need my own algorithm which doesn't include the dashes. http://duoduokou.com/csharp/33767822532036742008.html
