public static explicit operator bool (
	XAttribute attribute
)

The XAttribute to cast to Boolean.

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 an attribute with a Boolean value, then casts it to Boolean.


                XElement root = new XElement("Root", 
    new XAttribute("BoolValue", true)
);
bool bv = (bool)root.Attribute("BoolValue");
Console.WriteLine("(bool)BoolValue={0}", bv);

This example produces the following output:


(bool)BoolValue=True
