public static explicit operator Nullable<uint> (
	XAttribute attribute


Type: System.Xml.Linq.XAttribute

The XAttribute to cast to a Nullable<T> of UInt32.

Return Value

Type: System.Nullable<UInt32>

A Nullable<T> of UInt32 that contains the content of this XAttribute.

Exception Condition

The attribute does not contain a valid UInt32 value.

The following example creates an attribute with unsigned integer content. It then retrieves the value by casting to Nullable<T> of UInt32.

                XElement root = new XElement("Root", 
    new XAttribute("Att", 4294967295)
uint? value = (uint?)root.Attribute("Att");
Console.WriteLine("Nullable uint: value={0}", value == null ? "null" : value.ToString());

This example produces the following output:

Nullable uint: value=4294967295
