XNode.EqualityComparer Property

.NET Framework 4.5

Gets a comparer that can compare two nodes for value equality.

Namespace: System.Xml.Linq
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)

public static XNodeEqualityComparer EqualityComparer { get; }

Property Value

Type: System.Xml.Linq.XNodeEqualityComparer
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);

This example produces the following output:

Child 3 Information
