The following example creates an attribute with a Boolean value, then casts it to Boolean.


StringBuilder output = new StringBuilder();
XElement root = new XElement("Root",
    new XAttribute("BoolValue", true)
);
bool bv = (bool)root.Attribute("BoolValue");
output.Append("(bool)BoolValue=" + bv + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
