Definition

Namespace:

System.Xml.Linq

Assembly:

System.Xml.XDocument.dll

Source:

XNodeEqualityComparer.cs

Compares the values of two nodes.

 virtual bool System.Collections.IEqualityComparer.Equals(System::Object ^ x, System::Object ^ y) = System::Collections::IEqualityComparer::Equals;

bool IEqualityComparer.Equals (object x, object y);

abstract member System.Collections.IEqualityComparer.Equals : obj * obj -> bool
override this.System.Collections.IEqualityComparer.Equals : obj * obj -> bool

Function Equals (x As Object, y As Object) As Boolean Implements IEqualityComparer.Equals

Parameters

x

Object

The first XNode to compare.

y

Object

The second XNode to compare.

Returns

Boolean

true if the nodes are equal; otherwise false.

Implements

Equals(Object, Object)

Remarks

The following criteria determine whether two nodes are equal:

• A null node is equal to another null node but unequal to a non-null node.

• Two XNode objects of different types are never equal.

• Two XText nodes are equal if they contain the same text.

• Two XElement nodes are equal if they have the same tag name, the same set of attributes with the same values, and (ignoring comments and processing instructions), contain two equa-length sequences of pairwise equal content nodes.

• Two XDocument objects are equal if their root nodes are equal.

• Two XComment nodes are equal if they contain the same comment text.

• Two XProcessingInstruction nodes are equal if they have the same target and data.

• Two XDocumentType nodes are equal if the have the same name, public ID, system ID, and internal subset.
