Constructors

Base64(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Fields

Crlf
Obsolete.

Encoder flag bit to indicate lines should be terminated with a CRLF pair instead of just an LF.

Default
Obsolete.

Default values for encoder/decoder flags.

NoClose
Obsolete.

Flag to pass to Base64OutputStream to indicate that it should not close the output stream it is wrapping when it itself is closed.

NoPadding
Obsolete.

Encoder flag bit to omit the padding '=' characters at the end of the output (if any).

NoWrap
Obsolete.

Encoder flag bit to omit all line terminators (i.

UrlSafe
Obsolete.

Encoder/decoder flag bit to indicate using the "URL and filename safe" variant of Base64 (see RFC 3548 section 4) where - and _ are used in place of + and /.
