XmlWriter.WriteStringAsync(String) 方法

定義

以非同步的方式寫入指定的文字內容。Asynchronously writes the given text content.

public:
 virtual System::Threading::Tasks::Task ^ WriteStringAsync(System::String ^ text);
public virtual System.Threading.Tasks.Task WriteStringAsync (string text);
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

參數

text
String

要寫入的文字。The text to write.

傳回

Task

表示非同步 WriteString 作業的工作。The task that represents the asynchronous WriteString operation.

例外狀況

在先前的非同步作業完成前呼叫了 XmlWriter 方法。An XmlWriter method was called before a previous asynchronous operation finished. 在此情況下,會擲回 InvalidOperationException 與「非同步作業已經在進行中」的訊息。In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

-或--or-

在未將 Async 旗標設為 true的情況下呼叫了 XmlWriter 非同步方法。An XmlWriter asynchronous method was called without setting the Async flag to true. 在此情況下,就會擲回 InvalidOperationException 並顯示訊息「如果您要使用非同步方法,請將 XmlWriterSettings.Async 設為 true」。In this case, InvalidOperationException is thrown with the message "Set XmlWriterSettings.Async to true if you want to use Async Methods."

備註

這是的非同步版本 WriteString ,具有相同的功能。This is the asynchronous version of WriteString, with the same functionality. 若要使用這個方法,您必須將 Async 旗標設為 trueTo use this method, you must set the Async flag to true.
