This API is not CLS-compliant. 

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

public static explicit operator bool (
	XElement element
)

Parameters

element
Type: System.Xml.Linq.XElement

The XElement to cast to Boolean.

Return Value

Type: System.Boolean
A Boolean that contains the content of this XElement.

ExceptionCondition
FormatException

The element does not contain a valid Boolean value.

ArgumentNullException

The element parameter is null.

When converting to Boolean from an attribute or element, allowed values are "0", "1", and any string that produces "true" or "false" after trimming and conversion to lower case.

The following example creates some elements with boolean values. It then casts them to Boolean.

XElement root = new XElement("Root", 
    new XElement("BoolValue1", true),
    new XElement("BoolValue2", false)
);
bool bool1 = (bool)root.Element("BoolValue1");
bool bool2 = (bool)root.Element("BoolValue2");
Console.WriteLine("(bool)BoolValue1={0}", bool1);
Console.WriteLine("(bool)BoolValue2={0}", bool2);

This example produces the following output:

(bool)BoolValue1=True
(bool)BoolValue2=False
