XmlReader.ReadAttributeValue Method ()


When overridden in a derived class, parses the attribute value into one or more Text, EntityReference, or EndEntity nodes.

Namespace:   System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public abstract bool ReadAttributeValue()

Return Value

Type: System.Boolean

true if there are nodes to return.

false if the reader is not positioned on an attribute node when the initial call is made or if all the attribute values have been read.

An empty attribute, such as, misc="", returns true with a single node with a value of String.Empty.

Exception Condition

An XmlReader method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message “An asynchronous operation is already in progress.”

Use this method after calling MoveToAttribute to read through the text or entity reference nodes that make up the attribute value. The Depth of the attribute value nodes is one plus the depth of the attribute node; it increments and decrements by one when you step into and out of general entity references.
