This method reads the element content, decodes it using Base64 encoding, and returns the decoded binary bytes (for example, an inline Base64 encoded GIF image) into the buffer. 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.

This method can read only simple-content elements. The element can contain text, white space, significant white space, CDATA sections, comments, and processing instructions. It can also contain entity references, which are automatically expanded. The element cannot have child elements.

This method is very similar to the XmlValidatingReader.ReadContentAsBase64(Byte[], int, int) method except that it can be called only on element node types.

If the count value is higher than the number of bytes in the document, or if it is equal to the number of bytes in the document, the System.Xml.XmlValidatingReader reads all the remaining bytes in the document and returns the number of bytes read. The next System.Xml.XmlValidatingReader method call returns a zero and moves the reader to the node following the XmlNodeType.EndElement.

If you call XmlValidatingReader.Read before all of the element content is consumed, the reader may behave as if the first content was consumed and then the XmlValidatingReader.Read method was called. This means that the reader will read all the text until the end element is encountered. It will then read the end tag node, read the next node, and then position itself on the next subsequent node.
