Return Value

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.”


An XmlReader asynchronous method was called without setting the Async flag to true. In this case, InvalidOperationException is thrown with the message “Set XmlReaderSettings.Async to true if you want to use Async Methods.”

This is the asynchronous version of Read, with the same functionality. To use this method, you must set the Async flag to true.
