获取或设置仅表示该节点的子节点的标记。

public:
 virtual property System::String ^ InnerXml { System::String ^ get(); void set(System::String ^ value); };

public virtual string InnerXml { get; set; }

member this.InnerXml : string with get, set

Public Overridable Property InnerXml As String

属性值

String

此节点的子节点的标记，不包括默认属性。

例外

InvalidOperationException

在不能具有子节点的节点上设置该属性。

XmlException

设置此属性时指定的 XML 格式不正确。

示例

以下示例比较了属性InnerTextInnerXml。

#using <System.Xml.dll>

using namespace System;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<root>"
   "<elem>some text<child/>more text</elem>"
   "</root>" );
   XmlNode^ elem = doc->DocumentElement->FirstChild;
   
   // Note that InnerText does not include the markup.
   Console::WriteLine( "Display the InnerText of the element..." );
   Console::WriteLine( elem->InnerText );
   
   // InnerXml includes the markup of the element.
   Console::WriteLine( "Display the InnerXml of the element..." );
   Console::WriteLine( elem->InnerXml );
   
   // Set InnerText to a string that includes markup.  
   // The markup is escaped.
   elem->InnerText = "Text containing <markup/> will have char(<) and char(>) escaped.";
   Console::WriteLine( elem->OuterXml );
   
   // Set InnerXml to a string that includes markup.  
   // The markup is not escaped.
   elem->InnerXml = "Text containing <markup/>.";
   Console::WriteLine( elem->OuterXml );
}

using System;
using System.Xml;
public class Test {

  public static void Main() {
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<root>"+
                "<elem>some text<child/>more text</elem>" +
                "</root>");

    XmlNode elem = doc.DocumentElement.FirstChild;

    // Note that InnerText does not include the markup.
    Console.WriteLine("Display the InnerText of the element...");
    Console.WriteLine( elem.InnerText );

    // InnerXml includes the markup of the element.
    Console.WriteLine("Display the InnerXml of the element...");
    Console.WriteLine(elem.InnerXml);

    // Set InnerText to a string that includes markup.
    // The markup is escaped.
    elem.InnerText = "Text containing <markup/> will have char(<) and char(>) escaped.";
    Console.WriteLine( elem.OuterXml );

    // Set InnerXml to a string that includes markup.
    // The markup is not escaped.
    elem.InnerXml = "Text containing <markup/>.";
    Console.WriteLine( elem.OuterXml );
  }
}

Imports System.Xml

public class Test

  public shared sub Main()

    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<root>"& _
                "<elem>some text<child/>more text</elem>" & _
                "</root>")

    Dim elem as XmlNode = doc.DocumentElement.FirstChild

    ' Note that InnerText does not include the markup.
    Console.WriteLine("Display the InnerText of the element...")
    Console.WriteLine( elem.InnerText )

    ' InnerXml includes the markup of the element.
    Console.WriteLine("Display the InnerXml of the element...")
    Console.WriteLine(elem.InnerXml)

    ' Set InnerText to a string that includes markup.  
    ' The markup is escaped.
    elem.InnerText = "Text containing <markup/> will have char(<) and char(>) escaped."
    Console.WriteLine( elem.OuterXml )

    ' Set InnerXml to a string that includes markup.  
    ' The markup is not escaped.
    elem.InnerXml = "Text containing <markup/>."
    Console.WriteLine( elem.OuterXml )
    
  end sub
end class

注解

尝试从不能有子节点（例如 Text 节点）的节点设置此属性会引发异常。 否则，设置 InnerXml 会将节点的子节点替换为给定字符串的已分析内容。 分析在当前命名空间上下文中完成。

此属性是文档对象模型 (DOM) 的 Microsoft 扩展。

备注

InnerXml 不是修改 DOM 的有效方法。 替换复杂节点时可能会出现性能问题。 构造节点和使用方法（例如InsertBefore，InsertAfter``AppendChild以及）修改 RemoveChild Xml 文档更为高效。
