When overridden in a derived class, encodes the specified binary bytes as Base64 and writes out the resulting text.
Assembly: System.Xml (in System.Xml.dll)
For example, the byte buffer may contain the binary contents of a GIF image. This clearly would not be valid XML. The Base64 encoding is designed to represent arbitrary byte sequences in a text form comprised of the 65 US-ASCII characters ([A-Za-z0-9+/=]) where each character encodes 6 bits of the binary data.
