XmlNodeReader.Name 属性

定义

命名空间:

System.Xml

程序集:

System.Xml.ReaderWriter.dll

Source:

XmlNodeReader.cs

获取当前节点的限定名称。

public:
 virtual property System::String ^ Name { System::String ^ get(); };

public override string Name { get; }

member this.Name : string

Public Overrides ReadOnly Property Name As String

属性值

String

当前节点的限定名称。 例如， Namebk:book 用于元素 <bk:book>。

返回的名称取决于节点的 NodeType。 下列节点类型返回所列的值。 所有其他节点类型返回空字符串。

节点类型	名称
Attribute	属性名。
DocumentType	文档类型名称。
Element	标记名称。
EntityReference	引用的实体的名称。
ProcessingInstruction	处理指令的目标。
XmlDeclaration	字符串 xml。

示例

以下示例读取 XML 并显示每个节点。

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;

int main()

      doc->Load( filename );
      reader = gcnew XmlNodeReader( doc );
      
      //Parse the file and display each of the nodes.
      while ( reader->Read() )

  <Item>Test with a char entity: A</Item>
  <!-- Fourteen chars in this element.-->
  <Item>1234567890ABCD</Item>

注意

在 .NET Framework 2.0 中，建议的做法是使用 XmlReaderSettings 类和 Create 方法创建XmlReader实例。 这使你可以充分利用.NET Framework中引入的所有新功能。 有关详细信息，请参阅参考页中的 XmlReader “备注”部分。
