Reads and decodes the Base64 encoded contents of an element and stores the result in a byte buffer.
Parameters
- buffer
- Documentation for this section has not yet been entered.
- offset
- A int specifying the zero-based index into array where the method should begin to write.
- length
- Documentation for this section has not yet been entered.
- offset
- Documentation for this section has not yet been entered.
Returns
A int containing the number of bytes written to array, or zero if the current instance is not positioned on an element.
Exceptions
Type Reason ArgumentNullException array is null. ArgumentOutOfRangeException offset < 0, or len < 0.
- or -
len > array.Length - offset.
System.Xml.XmlException The Base64 sequence is not valid.
Remarks
Note:This method can be called successively to read large streams of embedded text.
Base64 encoding represents byte sequences in a text form comprised of the 65 US-ASCII characters (A-Z, a-z, 0-9, +, /, =) where each character encodes 6 bits of the binary data.
For more information on Base64 encoding, see RFC 2045 (http://www.ietf.org/rfc/2045).
