A XNodeEqualityComparer that can compare two nodes for value equality.
Examples
The following example uses this property to retrieve an XNodeEqualityComparer, which implements the System.Collections.IEqualityComparer and System.Collections.Generic.IEqualityComparer<T> interfaces. It creates a dictionary that uses this property.
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)
This example produces the following output:
Child 3 Information
