Cast the value of this XElement to a Nullable<T> of UInt32.

This API is not CLS-compliant.

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

public static explicit operator Nullable<uint> (
	XElement element
)

Parameters

element
Type: System.Xml.Linq.XElement

The XElement to cast to Nullable<T> of UInt32.

Return Value

Type: System.Nullable<UInt32>

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

Exception Condition
FormatException

The element does not contain a valid UInt32 value.

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


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

This example produces the following output:

Nullable uint: value=4294967295
