Reads the content and returns the Base64 decoded binary bytes.
Assembly: System.Xml (in System.Xml.dll)
- Type: System.Byte
The buffer into which to copy the resulting text. This value cannot be null.
- Type: System.Int32
The offset into the buffer where to start copying the result.
- Type: System.Int32
The maximum number of bytes to copy into the buffer. The actual number of bytes copied is returned from this method.
Return ValueType: System.Int32
The number of bytes written to the buffer.
The XmlValidatingReader class is obsolete in .NET Framework 2.0. You can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see the Remarks section of the XmlReader reference page..
This method streams the content, decodes the Base64 content, and returns the decoded binary bytes (for example, an inline Base64 encoded GIF image) into the buffer. This method can be called successively to read large streams of embedded text. For more information, see RFC 1521, "MIME (Multipurpose Internet Mail Extensions) Part One: Mechanisms for Specifying and Describing the Format of Internet Message Bodies". You can obtain RFCs from the Request for Comments Web site at http://www.rfc-editor.org.
You should not access any of the reader properties between calls to the method until the method returns the value 0.
This method has the following behavior:
returns the value 0 when it has reached the end of the byte stream it was operating on. The reader is positioned on the first non-content node.
If you ask for fewer, or the exact number, of bytes than are left in the stream, the reader remains in its current position.
is not supported on the following XML node types: Element, XmlDeclaration, None, Document, DocumentType, Notation, Entity, and DocumentFragment.
