The XElement 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 some elements with boolean values. It then casts them to Boolean.
StringBuilder output = new StringBuilder(); 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"); output.Append("(bool)BoolValue1=" + bool1 + Environment.NewLine); output.Append("(bool)BoolValue2=" + bool2 + Environment.NewLine); OutputTextBlock.Text = output.ToString();
