XmlTextWriter.XmlSpace 属性

定义

命名空间:

System.Xml

程序集:

System.Xml.ReaderWriter.dll

程序集:

System.Xml.dll

程序集:

netstandard.dll

获取表示当前 xml:space 范围的 XmlSpace。

public:
 virtual property System::Xml::XmlSpace XmlSpace { System::Xml::XmlSpace get(); };

public override System.Xml.XmlSpace XmlSpace { get; }

member this.XmlSpace : System.Xml.XmlSpace

Public Overrides ReadOnly Property XmlSpace As XmlSpace

属性值

XmlSpace

一个表示当前 XmlSpace 范围的 xml:space。

值	含义
无	如果不存在 xml:space 范围，则此为默认值。
默认	当前范围为 xml:space="default"。
保留	当前范围为 xml:space="preserve"。

示例

下面的示例使用 WriteWhitespace 该方法控制文件格式的方式。

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   
   // Create the writer.
   XmlTextWriter^ writer = nullptr;
   writer = gcnew XmlTextWriter( "ws.html", nullptr );
   
   // Write an element (this one is the root).
   writer->WriteStartElement( "p" );
   
   // Write the xml:space attribute.
   writer->WriteAttributeString( "xml", "space", nullptr, "preserve" );
   
   // Verify that xml:space is set properly.
   if ( writer->XmlSpace == XmlSpace::Preserve )
      Console::WriteLine( "xmlspace is correct!" );

   
   // Write out the HTML elements.  Insert white space
   // between 'something' and 'Big'
   writer->WriteString( "something" );
   writer->WriteWhitespace( "  " );
   writer->WriteElementString( "b", "B" );
   writer->WriteString( "ig" );
   
   // Write the root end element.
   writer->WriteEndElement();
   
   // Write the XML to file and close the writer.
   writer->Close();
}

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

public class Sample
{
  public static void Main()
  {
    // Create the writer.
    XmlTextWriter writer = null;
    writer = new XmlTextWriter ("ws.html", null);

    // Write an element (this one is the root).
    writer.WriteStartElement("p");

    // Write the xml:space attribute.
    writer.WriteAttributeString("xml", "space", null, "preserve");

    // Verify that xml:space is set properly.
    if (writer.XmlSpace == XmlSpace.Preserve)
      Console.WriteLine("xmlspace is correct!");

    // Write out the HTML elements.  Insert white space
    // between 'something' and 'Big'
    writer.WriteString("something");
    writer.WriteWhitespace("  ");
    writer.WriteElementString("b", "B");
    writer.WriteString("ig");

    // Write the root end element.
    writer.WriteEndElement();

    // Write the XML to file and close the writer.
    writer.Close();
  }
}

备注

从 .NET Framework 2.0 开始，我们建议使用XmlWriter.Create方法和XmlWriterSettings类创建XmlWriter实例，以利用新功能。

此属性允许一个组件找出另一个组件离开编写器的状态。
