When overridden in a derived class, closes the previous WriteStartAttribute call.
Assemblies: System.Xml (in System.Xml.dll)
System.Xml.ReaderWriter (in System.Xml.ReaderWriter.dll)
If you call WriteStartAttribute, you can close the attribute with this method.
When you use the XmlWriter methods to output XML, the elements and attributes will not be written until you call the Close method. For example, if you are using the XmlWriter to populate an XmlDocument, until you close the XmlWriter, you will not be able to observe the written elements and attributes in the target document.
For the asynchronous version of this method, see WriteEndAttributeAsync.
