XmlWriter.WriteWhitespaceAsync(String) XmlWriter.WriteWhitespaceAsync(String) XmlWriter.WriteWhitespaceAsync(String) XmlWriter.WriteWhitespaceAsync(String) Method

定義

以非同步的方式寫出指定的空白字元。Asynchronously writes out the given white space.

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

參數

ws
String String String String

空白字元的字串。The string of white space characters.

傳回

表示非同步 WriteWhitespace 作業的工作。The task that represents the asynchronous WriteWhitespace 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

這是非同步的WriteWhitespace,使用相同的功能。This is the asynchronous version of WriteWhitespace, with the same functionality. 若要使用此方法,您必須設定Async旗標設為trueTo use this method, you must set the Async flag to true.
