Valor da propriedade

XNodeEqualityComparer

Um XNodeEqualityComparer que pode comparar dois nós quanto à igualdade de valor.

Exemplos

O exemplo a seguir usa essa propriedade para recuperar um XNodeEqualityComparer, que implementa e System.Collections.IEqualityComparer System.Collections.Generic.IEqualityComparer<T> interfaces. Ele cria um dicionário que usa essa propriedade.

XElement xmlTree = new XElement("Root",  
    new XElement("Child1", 1),  
    new XElement("Child2", 2),  
    new XElement("Child3", 3),  
    new XElement("Child4", 4),  
    new XElement("Child5", 5)  
);  

Dictionary<XNode, string> nodeDictionary = new Dictionary<XNode, string>(XNode.EqualityComparer);  
nodeDictionary.Add(xmlTree.Element("Child5"), "Child 5 Information");  
nodeDictionary.Add(xmlTree.Element("Child3"), "Child 3 Information");  
nodeDictionary.Add(xmlTree.Element("Child1"), "Child 1 Information");  

string str = nodeDictionary[xmlTree.Element("Child3")];  
Console.WriteLine(str);  

Dim xmlTree As XElement = _   
        <Root>  
            <Child1>1</Child1>  
            <Child2>2</Child2>  
            <Child3>3</Child3>  
            <Child4>4</Child4>  
            <Child5>5</Child5>  
        </Root>  

Dim nodeDictionary As Dictionary(Of XNode, String) = New Dictionary(Of XNode, String)(XNode.EqualityComparer)  
nodeDictionary.Add(xmlTree.Element("Child5"), "Child 5 Information")  
nodeDictionary.Add(xmlTree.Element("Child3"), "Child 3 Information")  
nodeDictionary.Add(xmlTree.Element("Child1"), "Child 1 Information")  

Dim str As String = nodeDictionary(xmlTree.Element("Child3"))  
Console.WriteLine(str)

Esse exemplo gera a saída a seguir:

Child 3 Information
