Cast the value of this XElement to a Boolean.

This API is not CLS-compliant.

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

Public Shared Narrowing Operator CType (
	element As XElement
) As Boolean

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.

Exception Condition
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.


                Dim root As XElement = _ 
        <Root>
            <BoolValue1>true</BoolValue1>
            <BoolValue2>false</BoolValue2>
        </Root>
Dim bool1 As Boolean = CBool(root.Element("BoolValue1"))
Dim bool2 As Boolean = CBool(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
