Returns a value indicating whether two instances of XName are equal.

public:
 static bool operator ==(System::Xml::Linq::XName ^ left, System::Xml::Linq::XName ^ right);

public static bool operator ==(System.Xml.Linq.XName left, System.Xml.Linq.XName right);

public static bool operator ==(System.Xml.Linq.XName? left, System.Xml.Linq.XName? right);

static member ( = ) : System.Xml.Linq.XName * System.Xml.Linq.XName -> bool

Public Shared Operator == (left As XName, right As XName) As Boolean

Parameters

left: XName

The first XName to compare.

right: XName

The second XName to compare.

Returns

Boolean

true if left and right are equal; otherwise false.

Examples

The following example shows some comparisons between XName objects and strings.

XName xn;
xn = XName.Get("Root");
Console.WriteLine(xn == "Root");

xn = XName.Get("Root", "http://www.adventure-works.com");
Console.WriteLine(xn == "{http://www.adventure-works.com}Root");

XElement root = new XElement("Root", "content");
Console.WriteLine(root.Name == "Root");

Dim xn As XName
xn = XName.Get("Root")
Console.WriteLine(xn = "Root")

xn = XName.Get("Root", "http://www.adventure-works.com")
Console.WriteLine(xn = "{http://www.adventure-works.com}Root")

Dim root As XElement = New XElement("Root", "content")
Console.WriteLine(root.Name = "Root")

This example produces the following output:

True
True
True

Remarks

The operator overloads == and != are included to enable comparisons between XName and a string, such aselement.Name == "SomeElementName". The predefined reference equality operators in C# require one operand to be convertible to the type of the other through reference conversions only. These operators do not consider the implicit conversion from string to XName.
