XmlReader.ReadInnerXmlAsync Method

Definition

Asynchronously reads all the content, including markup, as a string.

public:
 virtual System::Threading::Tasks::Task<System::String ^> ^ ReadInnerXmlAsync();
public virtual System.Threading.Tasks.Task<string> ReadInnerXmlAsync ();
abstract member ReadInnerXmlAsync : unit -> System.Threading.Tasks.Task<string>
override this.ReadInnerXmlAsync : unit -> System.Threading.Tasks.Task<string>
Public Overridable Function ReadInnerXmlAsync () As Task(Of String)

Returns

All the XML content, including markup, in the current node. If the current node has no children, an empty string is returned.

Exceptions

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."

-or-

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."

Remarks

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

This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by ReadInnerXml().
