public virtual System.Threading.Tasks.Task WriteStringAsync (string? text);

abstract member WriteStringAsync : string -> System.Threading.Tasks.Task
override this.WriteStringAsync : string -> System.Threading.Tasks.Task

Public Overridable Function WriteStringAsync (text As String) As Task

Parameters

text

String

The text to write.

Returns

Task

The task that represents the asynchronous WriteString operation.

Exceptions

InvalidOperationException

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

Remarks

This is the asynchronous version of WriteString, 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 WriteString(String).
