XDocumentType.NodeType 属性

定义

获取此节点的节点类型。Gets the node type for this node.

public:
 virtual property System::Xml::XmlNodeType NodeType { System::Xml::XmlNodeType get(); };
public override System.Xml.XmlNodeType NodeType { get; }
member this.NodeType : System.Xml.XmlNodeType
Public Overrides ReadOnly Property NodeType As XmlNodeType

属性值

XmlNodeType

节点类型。The node type. 对于 XDocumentType 对象,此值为 DocumentTypeFor XDocumentType objects, this value is DocumentType.

示例

下面的示例演示如何使用此属性检索对象的节点类型 XDocumentTypeThe following example shows the use of this property to retrieve the node type for an XDocumentType object.

string internalSubset = @"<!ELEMENT Pubs (Book+)>  
<!ELEMENT Book (Title, Author)>  
<!ELEMENT Title (#PCDATA)>  
<!ELEMENT Author (#PCDATA)>";  

string target = "xml-stylesheet";  
string data = "href=\"mystyle.css\" title=\"Compact\" type=\"text/css\"";  

XDocument doc = new XDocument(  
    new XComment("This is a comment."),  
    new XProcessingInstruction(target, data),  
    new XDocumentType("Pubs", null, null, internalSubset),  
    new XElement("Pubs",   
        new XElement("Book",  
            new XElement("Title", "Artifacts of Roman Civilization"),  
            new XElement("Author", "Moreno, Jordao")  
        ),  
        new XElement("Book",  
            new XElement("Title", "Midieval Tools and Implements"),  
            new XElement("Author", "Gazit, Inbar")  
        )  
    ),  
    new XComment("This is another comment.")  
);  
doc.Declaration = new XDeclaration("1.0", "utf-8", "true");  

Console.WriteLine(doc.DocumentType.NodeType);  
Dim internalSubset = _  
    "<!ELEMENT Pubs (Book+)>" & Environment.NewLine & _  
    "<!ELEMENT Book (Title, Author)>" & Environment.NewLine & _  
    "<!ELEMENT Title (#PCDATA)>" & Environment.NewLine & _  
    "<!ELEMENT Author (#PCDATA)>"  

Dim doc As XDocument = _   
    <?xml version="1.0" encoding="utf-8" standalone="yes"?>  
    <!--This is a comment.-->  
    <?xml-stylesheet href='mystyle.css' title='Compact' type='text/css'?>  
    <Pubs>  
        <Book>  
            <Title>Artifacts of Roman Civilization</Title>  
            <Author>Moreno, Jordao</Author>  
        </Book>  
        <Book>  
            <Title>Midieval Tools and Implements</Title>  
            <Author>Gazit, Inbar</Author>  
        </Book>  
    </Pubs>  
    <!--This is another comment.-->  

doc.FirstNode.AddAfterSelf(new XDocumentType("Pubs", Nothing, Nothing, internalSubset))  

Console.WriteLine(doc.DocumentType.NodeType.ToString())  

该示例产生下面的输出:This example produces the following output:

DocumentType  

注解

由于派生自的所有类都 XObject 包含一个 NodeType 属性,因此你可以编写对的具体子类的集合进行操作的代码 XObjectBecause all classes that derive from XObject contain a NodeType property, you can write code that operates on collections of concrete subclass of XObject. 然后,你的代码可以测试集合中每个节点的节点类型。Your code can then test for the node type of each node in the collection.
