XmlWriter.Flush 方法

定义

命名空间:
System.Xml
程序集:
System.Xml.dll, System.Xml.ReaderWriter.dll
程序集:
netstandard.dll, System.Xml.ReaderWriter.dll

在派生类中重写时，将缓冲区中的内容刷新到基础流，并刷新基础流。

public:
 abstract void Flush();
public abstract void Flush();
abstract member Flush : unit -> unit
Public MustOverride Sub Flush ()

例外

InvalidOperationException

在上一个异步操作完成之前调用了一个 XmlWriter 方法。 在这种情况下， InvalidOperationException 会引发消息“正在进行异步操作”。

示例

以下示例写入两个 XML 片段。

using System;
using System.IO;
using System.Xml;

public class Sample {

  public static void Main() {

     // Create an XmlWriter to write XML fragments.
     XmlWriterSettings settings = new XmlWriterSettings();
     settings.ConformanceLevel = ConformanceLevel.Fragment;
     settings.Indent = true;
     XmlWriter writer = XmlWriter.Create(Console.Out, settings);

     // Write an XML fragment.
     writer.WriteStartElement("book");
     writer.WriteElementString("title", "Pride And Prejudice");
     writer.WriteEndElement();
     writer.Flush();

     // Write another XML fragment.
     writer.WriteStartElement("cd");
     writer.WriteElementString("title", "Americana");
     writer.WriteEndElement();
     writer.Flush();

     // Close the writer.
     writer.Close();
  }
}

Imports System.IO
Imports System.Xml

Public Class Sample

  Public Shared Sub Main()

     ' Create an XmlWriter to write XML fragments.
     Dim settings As XmlWriterSettings = new XmlWriterSettings()
     settings.ConformanceLevel = ConformanceLevel.Fragment
     settings.Indent = true
     Dim writer As XmlWriter = XmlWriter.Create(Console.Out, settings)
    
     ' Write an XML fragment.
     writer.WriteStartElement("book")
     writer.WriteElementString("title", "Pride And Prejudice")
     writer.WriteEndElement()
     writer.Flush()

     ' Write another XML fragment.
     writer.WriteStartElement("cd")
     writer.WriteElementString("title", "Americana")
     writer.WriteEndElement()
     writer.Flush()  

     'Close the writer.
     writer.Close()

  End Sub
End Class

注解

这是调用的，而不是 Close 当你想要向基础流写入更多内容而不丢失缓冲区中的内容时。
